This study uses nighttime satellite light data to examine the impact and mechanism of the digitalization of listed companies on employees' amount of overtime work and further discusses the issue of income compensation for such work. The results show that digitalization increases employees' amount of overtime work through the market expansion mechanism and the technological innovation mechanism. In addition, digitalization can increase the total revenue and average wage of enterprises; that is, there is an income compensation effect for overtime work. This study also reveals that listed companies' more positive attitudes toward digitalization can effectively weaken the overtime work problem caused by digitalization. This study advocates optimizing the operational efficiency of digitalization while safeguarding employee rights, thus fostering sustainable synergy between organizations and workforces during digital transformation. Business and commerce/Business and management Social science/Business and management Business and commerce/Economics Social science/Economics Earth and environmental sciences/Environmental social sciences Introduction In the contemporary global economic landscape, overtime work has emerged as a prevalent and concerning issue across various countries and industries (Autor, et al., 2024 , Grigsby, et al., 2021 ). A multitude of factors, including intensifying global competition, the rapid pace of technological innovation, and ever-changing market demands, have contributed to the widespread occurrence of overtime work (Qin, et al., 2022 , Wang, et al., 2025 , Yu, et al., 2025 ). With the continuous promotion of high-quality development in China, in recent years, work systems such as "007" (working around the clock, seven days a week) and "996" (working from 9 am to 9 pm, six days a week) have emerged. The phenomenon of overtime work is gradually becoming more prominent and serious and has already become a core issue of wide focused among all sectors of society. Overtime work has become a widely adopted work model in enterprises. Such a model involves not only the physical and mental health and rights protection of many workers but also the promotion of China's high-quality development strategy (Wang and Zhao, 2024 ). Moreover, as an important aspect influencing human social life, digitalization has received widespread attention from all sectors of society (Brynjolfsson, et al., 2025 , Gornick, 2016 , Hu, 2025 ). Digitalization usually brings about changes in business models and the application of new technologies (Norton and Shapiro, 2023 , Xu, et al., 2024 ). Employees need to adapt to these changes and continuously learn and become accustomed to new technologies and tools, thus strengthening their work burden (Du and Li, 2025 ). Therefore, it is necessary to organically combine research on the digitalization of listed companies and employees' amount of overtime work to open the "black box" of the rights and interests of enterprise workers under digitalization. Will the digitalization of enterprises increase employees' amount of overtime work? If so, what is the underlying mechanism of this impact? Can this overtime work be effectively compensated? To answer the above questions, this article uses the matching data of listed companies and nighttime lights. Through microeconometric analysis, this study examines the impact mechanisms and compensation effects of digitalization on employees' amount of overtime work. Clarifying these issues can help enterprises better balance the efficiency of transformation and the protection of employees' rights and interests and contribute to the construction of a more reasonable pattern of labor relations during the digitalization period. This study has several innovative aspects. Methodologically, instead of relying on conventional research data, nighttime satellite light data are used to measure employees' overtime work, which overcomes the limitations of subjective biases in questionnaires. Moreover, this work combines Python-based text recognition technology with annual report data to measure the level of enterprise digitalization. This data measurement approach, paired with microeconometric models, ensures more objective and accurate research results. In terms of research content, existing studies focus mostly on the influence of enterprise digitalization on performance and technology. In contrast, this work explores its influence on employees' number of working hours, delving into the scale expansion and technological innovation mechanisms behind the increase in the amount of overtime work. Furthermore, this study takes a new approach to the moderating function of corporate executives' digital attitudes, offering a more complete understanding of the interaction among digitalization, management, and employees. The remainder of this article are organized as follows. Section 2 defines enterprise digitalization and proposes hypotheses about its impact on employees' amount of overtime work. Section 3 designs the research by constructing an econometric model and selecting relevant variables, with data sourced from multiple channels. Section 4 presents empirical estimations, including benchmark analysis, endogeneity analysis, and mechanism analysis. Section 5 further discusses wage compensation for overtime work and the influence of corporate executives' digital attitudes. The final section draws conclusions and presents policy implications. Theoretical analysis and hypotheses Enterprise digitalization refers to the use of digital technologies to break down data barriers between different levels and industries, thereby creating new businesses, business forms, and business models (Chen, et al., 2024 , Shao, et al., 2024 ). Enterprises rely on digital technology for modernization, with data as the core element and data empowerment as the main line, with the goal of increasing production volume and efficiency (Li, et al., 2025 , Li, et al., 2025 , Yu, et al., 2024 ). Enterprise digitalization has a continuous and profound effect on the enterprise’s organizational structure (Mustafa, et al., 2022 , Zhang, et al., 2025 ), business scope (Kohtamäki, et al., 2024 ), and employment model (Cirillo, et al., 2021 ). All these changes in factors are likely to lead to overtime work among enterprise employees (Fang, et al., 2025 , Norden and Ribeiro, 2025 ). Digitalization can increase employees' number of working hours by facilitating the expansion of enterprise scale (Franco and Suppressa, 2025 , Zhang, et al., 2025 ). Digital technology provides firms with more efficient management tools and greater market reach (Du, et al., 2025 , Liu, et al., 2025 ). Through big data analysis, companies can better understand market demand, optimize production processes, and thus make more informed decisions about business expansion (Boerner, et al., 2025 , Wu, et al., 2025 ). This expansion often leads to increased workloads. Moreover, digitalization also heightens competition (Yan, et al., 2024 , Zhang, et al., 2025 ). To maintain a competitive edge in the digitally driven market, enterprises may push employees to work longer hours to ensure faster product development, more responsive customer service, and more efficient operations (He and Yi, 2023 , Liu, et al., 2025 , Shen, et al., 2025 ). This competitive pressure further contributes to the increase in employees' number of working hours as an enterprise expands under the influence of digitalization (Aránega, et al., 2025 , Martindale and Lehdonvirta, 2023 ). Digitalization can lead to an increase in employees' number of working hours by promoting corporate technological innovation. Digitalization offers enterprises abundant resources and tools for technological innovation (Andres, et al., 2025 , Chen, et al., 2024 , Yan, et al., 2025 ). Advanced digital research and development (R&D) platforms allow companies to conduct in-depth R&D more quickly (Wang and Wei, 2025 , Zheng, et al., 2025 ). Big data analytics helps in identifying market trends and customer needs precisely, which in turn guides targeted innovation (Magistretti, et al., 2025 ). When enterprises are engaged in technological innovation spurred by digitalization, they often face several situations that drive up employees' number of working hours (Mao, et al., 2025 , Neumann, 2025 ). During the process of technological innovation, new product or service development requires a high degree of concentration and continuous effort (Affandi, et al., 2024 , Ma and Lin, 2025 ). Employees in R&D departments, in particular, need to spend extra time testing, debugging, and optimizing new technologies. Furthermore, after the successful implementation of technological innovation, enterprises usually need to rapidly integrate new technologies into their operations (Çela, et al., 2024 , Zhang, et al., 2025 ). This integration phase also demands considerable time and effort from employees (Maione, et al., 2024 ). As digitalization accelerates the pace of technological innovation, the frequency and intensity of these situations increase, ultimately resulting in more overtime for employees. Therefore, two hypotheses are presented as follows: Hypotheses 1: The digitalization of enterprises increases the amount of overtime work among enterprise workers. Hypotheses 2: The scale expansion effect and technological innovation effect are the internal mechanisms through which digitalization leads to employees' overtime. Research design Econometric model. To investigate the influence of digitalization on overtime work, this benchmark study adopts the following panel two-way fixed effects model: $$O{W_{it}}=\alpha +\beta D{T_{it}}+\gamma {X_{it}}+{\eta _i}+{\nu _t}+{\varepsilon _{it}}$$ 1 where i denotes individual enterprises and t represents periods. OW it is the dependent variable, operationalized by quantifying the brightness of corporate nighttime lighting data from listed companies. DT it serves as the core explanatory variable, measured through the automated text analysis of annual reports to calculate digitalization-related word frequencies. X it consists of control variables that incorporate key production/operation characteristics. η i captures unobserved time-invariant firm-specific fixed effects, and ν t accounts for macroeconomic and policy-related year fixed effects. ε it represents the idiosyncratic error term with standard assumptions. The explained variable is the overtime work variable OW it of listed companies. In the literature (Barentine, 2022 , Xuan and Wu, 2023 ), the criterion for determining whether an enterprise is in a state of overtime work is based on comparison standards in terms of time and space dimensions. The reason for this is due to, unlike questionnaires, which are easily interfered with by factors such as subjective cognitive biases and personal willingness tendencies, satellite nighttime light data are obtained via remote sensing technology. Such technology can continuously collect information over a long time span and covers a vast geographical area. These characteristics are more in line with the needs of empirical research on large samples than are those of other approaches. The building method is as follows: on the one hand, the nighttime light brightness of listed company i during legal holidays is taken as the comparison benchmark in the time dimension. When the nighttime light brightness of listed company i is greater than that during legal holidays, the high light brightness may not be an inherent characteristic of the grid where the listed company is located but rather caused by the company's nighttime overtime work. On the other hand, the nighttime light brightness of the district or county where listed firm i is located is used as the comparison benchmark in the spatial dimension. When the nighttime light brightness of listed company i is greater than that of the district or county where it is located, it may also reflect the company's nighttime overtime work situation rather than the spillover effect generated by the surrounding infrastructure construction. In summary, when listed company i meets both the time and spatial dimension criteria simultaneously, it is defined as being in a state of overtime work. The overtime work variable OW it of the listed company then counts the number of overtime work days of listed firm i in year t . The explanatory variable is digitalization DT it . In the literature (Bao, et al., 2023 , Wu, et al., 2021 ), which is based on the text recognition function of Python crawlers, and taking the annual reports of listed firms in the Shanghai and Shenzhen stock markets as the basis, a specific keyword set for digitalization is selected, and keywords with negative words and those that do not belong to the company itself are excluded. The method of searching, matching, and summing keywords is adopted to depict the level of digitalization of enterprises. The control variable is X it , which incorporates key enterprise-level production and operation characteristics to account for potential confounding effects. These variables are selected on the basis of their theoretical relevance to both overtime work patterns and digitalization adoption. Specifically, the firm scale variable Scale is operationalized as the natural logarithm of total assets, which captures economies of scale and resource endowment effects; the capital structure variable CS is measured by the total debt-to-assets ratio, reflecting financial leverage and risk management strategies; the capital intensity variable CI is calculated as fixed assets per employee, representing the technology-intensive nature of production processes; the profitability variable Profit is operationalized as return on assets, capturing the efficiency of asset utilization and overall financial performance; and the ownership concentration variable OC is measured by the percentage of shares held by the largest shareholder, reflecting governance structures and agency costs. Data sources. Overtime work indicators for listed firms are derived mostly from nighttime light data provided by the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor on the National Polar-orbiting Partnership (NPP) satellite in the United States. This data product has provided daily frequency nighttime light data since January 19, 2012. The Python programming language is used to analyze and process the relevant data. Specifically, through the longitude and latitude coordinate information of the office address disclosed in the annual report of the listed company, the company is mapped to the corresponding grid position with the help of a specific positioning algorithm, and then, the operation of reading the nighttime light brightness data of the grid where the enterprise is located is realized, providing data support for subsequent research and analysis. Digitalization data for listed companies are derived from annual reports of all A-share firms listed on the Shanghai and Shenzhen Stock Exchanges. A Python-based web crawler is employed to systematically collect and organize these reports, which are then processed using the Java-based PDFbox library to extract full-text content. This forms the textual database for subsequent text mining analysis to identify digitalization-related keywords. Firm characteristic data are obtained from three primary sources—the China Stock Market & Accounting Research (CSMAR) database, which is a core dataset for financial and operational metrics; the Wind Database, which includes supplementary data on market indices and corporate governance; and the China Research Data Service Platform (CNRDS), which includes additional macroeconomic and industry-level variables. The final sample spans an 11-year period (2012–2022) with annual observations. The descriptive statistics for key variables are presented in Table 1 , providing a foundational overview of the dataset characteristics. Table 1 Descriptive statistics of key variables.

On the basis of the benchmark equation, a panel two-way fixed effects model is employed to control for individual and year fixed effects. In addition, considering the possible problem of heteroscedasticity, during the regression process, logarithmic transformation is carried out on variables with relatively large data fluctuations. The findings are reported in Table 2 . In Column (1) of Table 2 , the overtime work variable of listed companies is used as the dependent variable, and only the digitalization variable is introduced as the explanatory variable. Column (2) further introduces the production, operation, and management characteristics at the company level. Moreover, Columns (3) and (4) use overtime work on working days and overtime work on weekends, respectively, as the dependent variables to further examine the influence of digitalization on the overtime work of firms. The findings in Columns (1) and (2) of Table 2 reveal that the coefficient of the digitalization variable is positive, indicating that the increased digitalization of listed companies increases employees' overtime work. A possible explanation for this is that digitalization usually brings about changes in business models and applications of new technologies. Moreover, digitalization may lead to adjustments in the company's organizational structure and the optimization of business processes. Employees need to adapt to these changes and continuously learn and become accustomed to new technologies and tools, thus resulting in an increase in employees' work burden and the need to work overtime to complete corresponding tasks. A comparison of the digital variables of listed companies in Columns (1) and (2) reveals that if the production and management characteristics of a company are not considered, then the impact of digitalization on employees' amount of overtime work will be overestimated. In addition, the findings in Columns (3) and (4) show that the digitalization variable is also positive, indicating that the digitalization of the company increases employees' amount of overtime work both on weekends and nonweekends. The control variables produce outcomes that are consistent with expectations. The regression coefficients for the firm scale are all significantly negative, showing that the larger the company scale is, the less overtime work. Large-scale companies usually have more complete management systems and resource allocations, enabling them to arrange work more reasonably, than do small-scale companies. The regression coefficients of capital intensity are all significantly positive, suggesting that the stronger the capital intensity is, the more serious the overtime work situation. Capital-intensive enterprises require more human input and technical support during the production or operation process, leading to increased levels of work pressure on employees and longer overtime hours. The regression coefficient for ownership concentration is negative, implying that a higher level of ownership concentration may diminish the likelihood of overtime work. The regression coefficients of capital structure and profitability are not significant in all columns, indicating that the impacts of capital structure and profitability on overtime work are not obvious within the sample interval.

Robust standard errors appear in parentheses. Endogeneity analysis. Because the two-way causal link between variables and omitted factors can cause endogeneity difficulties, we adjust for endogeneity bias by identifying relevant instrumental variables. Columns (1) and (2) of Table 3 introduce the digital attention of the government and the public in the cities where listed firms are situated as instrumental variables. The government's digital attention is assessed using official work reports and the frequency of digital-related terms, whereas the Baidu search index is used to measure the public's digital attention. On the one hand, when the government in the region where a listed business is based is more concerned with digital concerns, the firm is more likely to gain government backing and advantageous policies if it actively participates in digitalization. On the other hand, when the public in the region where a listed business is based is more concerned with digital concerns and the firm actively pursues digitalization, then its corporate reputation and product impacts are more likely to be recognized and preferred by customers. As a result, if the government and the general public in the region where a listed firm is based pay more attention to digitalization, then the listed company is more likely to improve its digitalization efforts, achieving the correlation criterion. Furthermore, macroeconomic variables are less likely to be influenced by company overtime work, hence satisfying the condition of instrumental variable exogeneity. Columns (3) and (4) of Table 3 introduce digitalization at the regional and industry levels, respectively, as instrumental variables. On the basis of the digitalization situations of listed companies in the respective cities and industries, the digitalization situations of the cities and industries where the listed companies are located are aggregated, and the digitalization situation of the company itself is deducted. The results in Table 3 reveal that when endogeneity is controlled for, all of the coefficients of digitalization are considerably positive, implying that digitalization will increase the amount of enterprise employee overtime. In addition, weak instrumental variable tests and overidentification tests are used for the instrumental variables. The test findings reject the null hypothesis, demonstrating the efficiency of the instrumental variables. Table 3 Endogeneity analysis.

The p values for the statistics are indicated in parentheses. Mechanism analysis. It has been verified earlier that digitalization leads to employees' overtime work, and further exploration of its mechanisms is necessary. First, digital development leads to the expansion of the enterprise's business scale and business transformation, thereby generating a greater workload. The scale expansion effect prompts employees to work overtime. Second, with the implementation of the enterprise's digitalization strategy, the enterprise's R&D and innovation activities tend to increase. Moreover, R&D investment has obvious characteristics of skill bias, which generate greater demand for highly skilled labor in the enterprise. Through the technological innovation effect, this situation prompts employees to work overtime. On this basis, the market expansion mechanism and technological innovation mechanism are tested. The market expansion mechanism is assessed according to the rate of increase in operating revenue and inventory turnover, whereas the technical innovation mechanism is measured by the number of digital patent applications and R&D workers. The findings are shown in Table 4 . Columns (1) and (2) show the market expansion mechanism. The impacts of digitalization on a company's revenue growth and inventory turnover are significantly positive. That is, digitalization usually leads to the expansion of the market scale. Employees need to continuously learn and adapt to new businesses, which increases their work burden and makes them need to work overtime to complete corresponding tasks. Columns (3) and (4) report the technological innovation mechanism. The impacts of digitalization on the numbers of patent applications and R&D personnel of enterprises are significantly positive. That is, intelligent development can promote innovative collaboration and knowledge sharing and generate greater demand for highly skilled labor. Compared with routine and repetitive low-skilled jobs, highly skilled jobs are more likely to involve overtime work. Table 4 Mechanism analysis.

Digitalization leads to the expansion of enterprise scale and technological innovation. Employees need to continuously learn and adapt to new technologies and tools, which increases their work burden and requires them to work overtime to complete corresponding tasks. Thus, whether the overtime work brought about by digitalization is compensated through income is a question that still needs further verification. In Columns (1) and (3) of Table 5 , the employee compensation payable by listed companies and the average wage are introduced as the explained variables, respectively. The results show that the coefficients of the digitalization variables are all significantly positive, indicating that the digitalization of listed companies can increase the overall income and average wage of employees, resulting in an increase in employees' income. In addition, although digitalization can increase the employee compensation payable and the average wage of listed companies, is it compensation for overtime work? Columns (2) and (4) introduce the interaction terms between digitalization and overtime work, respectively. The findings show that the interaction terms are positive and significant and that the coefficients of the digitalization variables are no longer significant. This finding indicates that overtime work is an important reason for the increase in employee compensation payable and the average wage of listed companies due to digitalization. That is, digitalization leads to employees' overtime work, but it also provides certain income compensation to employees for such work.

As the microsubjects of economic activities, the digital attitude of a firm's managers directly affects the effectiveness of its digitalization. The annual report texts of the management issued by the company contain incremental information and can reflect the details, logic, and evidence that cannot be reflected in quantitative information. When the digital attitude of the company's management is more positive, it presents positive expectations for the firm's digitalization in the annual report. Therefore, this article takes the annual report texts of the management of listed firms as the carrier. The sentiment analysis dictionary of CNKI HowNet differentiates positive and negative emotion words, automatically segments texts using Python's Chinese word segmentation package, and counts word frequencies. Then, the indicators of the proportion of digital positive word frequencies and the proportion of digital negative word frequencies of listed companies are constructed. The findings are reported in Table 6 . When the degree of digitalization of listed companies is fixed, if the management of a company holds a more positive attitude toward digitalization, then the extent to which digitalization leads to an increase in employees' amount of overtime work in listed companies will be weakened. When management holds a positive digital attitude, during the digitalization process, the enterprise pays more attention to improving efficiency through reasonable planning and efficient process design rather than simply relying on increasing employees' number of working hours. For listed companies whose management holds a negative attitude toward digitalization, the extent to which digitalization leads to an increase in employees' amount of overtime work in listed companies will be strengthened. A negative digital attitude may manifest as a company's lack of clear strategies and plans during the digitalization process, resulting in chaos and inefficiency. As a result, employees need to spend more time solving these problems, thus increasing their number of overtime hours. Table 6 Digitalization, attitudes of upper management and overtime work.

The results show that with the digitalization of listed companies, employees' amount of overtime work will increase to a certain extent, and this conclusion still holds after controlling for the endogeneity problem. The analysis of the mechanism shows that digitalization affects employees' amount of overtime work through the market expansion mechanism and the technological innovation mechanism. Further discussion shows that the digitalization of listed companies can increase the total income and average salary of employees and that overtime work is an important reason for the increase in income compensation brought about by digitalization. In addition, when the degree of digitalization of listed companies is certain, if the management of the company holds a positive attitude toward digitalization, then it can reduce the amount of employees' overtime work caused by digitalization. If the management of a company holds a negative attitude toward digitalization, then it can increase the amount of employees' overtime work caused by digitalization. On the basis of the research findings, this study proposes the below policy suggestions. First, governments advancing enterprise digitalization must enact regulatory frameworks for monitoring labor practices. While acknowledging the productivity benefits of digitalization, mandatory measures should prevent exploitative overtime as a digitalization driver. Legislative initiatives must define the maximum number of working hours during digital transitions, curbing corporate tendencies to prioritize transformation velocity over workforce well-being. Second, governments must implement sector-specific regulations that steer corporate strategies through industrial policies. This curbs innovation arbitrage, where market share competition drives exploitative overtime practices. Legislative frameworks should establish legally binding overtime thresholds with premium compensation during R&D cycles, mandating phased innovation roadmaps aligned with workforce sustainability metrics. Enterprises are obligated to synchronize project timelines with human resource capacities and implement task distribution algorithms to prevent workload clustering. Finally, the issue of excessive overtime in digital transformation requires structural adjustment through organizational culture building. Governments should employ policy incentives and public advocacy to guide enterprises in integrating humanistic considerations into digitalization strategies. Enterprises must cultivate digital organizational cultures that emphasize bidirectional empowerment. This stratified governance model enhances organizational resilience, achieving synergistic evolution between technological adoption and labor rights protection.

A multitude of factors, including intensifying global competition, the rapid pace of technological innovation, and ever-changing market demands, have contributed to the widespread occurrence of overtime work (Qin, et al., \u003cspan citationid=\"CR35\" class=\"CitationRef\"\u003e2022\u003c/span\u003e, Wang, et al., \u003cspan citationid=\"CR39\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Yu, et al., \u003cspan citationid=\"CR47\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). With the continuous promotion of high-quality development in China, in recent years, work systems such as \"007\" (working around the clock, seven days a week) and \"996\" (working from 9 am to 9 pm, six days a week) have emerged. The phenomenon of overtime work is gradually becoming more prominent and serious and has already become a core issue of wide focused among all sectors of society. Overtime work has become a widely adopted work model in enterprises. Such a model involves not only the physical and mental health and rights protection of many workers but also the promotion of China's high-quality development strategy (Wang and Zhao, \u003cspan citationid=\"CR38\" class=\"CitationRef\"\u003e2024\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eMoreover, as an important aspect influencing human social life, digitalization has received widespread attention from all sectors of society (Brynjolfsson, et al., \u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Gornick, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e2016\u003c/span\u003e, Hu, \u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). Digitalization usually brings about changes in business models and the application of new technologies (Norton and Shapiro, \u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e2023\u003c/span\u003e, Xu, et al., \u003cspan citationid=\"CR43\" class=\"CitationRef\"\u003e2024\u003c/span\u003e). Employees need to adapt to these changes and continuously learn and become accustomed to new technologies and tools, thus strengthening their work burden (Du and Li, \u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). Therefore, it is necessary to organically combine research on the digitalization of listed companies and employees' amount of overtime work to open the \"black box\" of the rights and interests of enterprise workers under digitalization. Will the digitalization of enterprises increase employees' amount of overtime work? If so, what is the underlying mechanism of this impact? Can this overtime work be effectively compensated? To answer the above questions, this article uses the matching data of listed companies and nighttime lights. Through microeconometric analysis, this study examines the impact mechanisms and compensation effects of digitalization on employees' amount of overtime work. Clarifying these issues can help enterprises better balance the efficiency of transformation and the protection of employees' rights and interests and contribute to the construction of a more reasonable pattern of labor relations during the digitalization period.\u003c/p\u003e \u003cp\u003eThis study has several innovative aspects. Methodologically, instead of relying on conventional research data, nighttime satellite light data are used to measure employees' overtime work, which overcomes the limitations of subjective biases in questionnaires. Moreover, this work combines Python-based text recognition technology with annual report data to measure the level of enterprise digitalization. This data measurement approach, paired with microeconometric models, ensures more objective and accurate research results. In terms of research content, existing studies focus mostly on the influence of enterprise digitalization on performance and technology. In contrast, this work explores its influence on employees' number of working hours, delving into the scale expansion and technological innovation mechanisms behind the increase in the amount of overtime work. Furthermore, this study takes a new approach to the moderating function of corporate executives' digital attitudes, offering a more complete understanding of the interaction among digitalization, management, and employees.\u003c/p\u003e \u003cp\u003eThe remainder of this article are organized as follows. Section 2 defines enterprise digitalization and proposes hypotheses about its impact on employees' amount of overtime work. Section 3 designs the research by constructing an econometric model and selecting relevant variables, with data sourced from multiple channels. Section 4 presents empirical estimations, including benchmark analysis, endogeneity analysis, and mechanism analysis. Section 5 further discusses wage compensation for overtime work and the influence of corporate executives' digital attitudes. The final section draws conclusions and presents policy implications.\u003c/p\u003e"},{"header":"Theoretical analysis and hypotheses","content":"\u003cp\u003eEnterprise digitalization refers to the use of digital technologies to break down data barriers between different levels and industries, thereby creating new businesses, business forms, and business models (Chen, et al., \u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e2024\u003c/span\u003e, Shao, et al., \u003cspan citationid=\"CR36\" class=\"CitationRef\"\u003e2024\u003c/span\u003e). Enterprises rely on digital technology for modernization, with data as the core element and data empowerment as the main line, with the goal of increasing production volume and efficiency (Li, et al., \u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Li, et al., \u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Yu, et al., \u003cspan citationid=\"CR48\" class=\"CitationRef\"\u003e2024\u003c/span\u003e). Enterprise digitalization has a continuous and profound effect on the enterprise\u0026rsquo;s organizational structure (Mustafa, et al., \u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e2022\u003c/span\u003e, Zhang, et al., \u003cspan citationid=\"CR49\" class=\"CitationRef\"\u003e2025\u003c/span\u003e), business scope (Kohtam\u0026auml;ki, et al., \u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e2024\u003c/span\u003e), and employment model (Cirillo, et al., \u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e2021\u003c/span\u003e). All these changes in factors are likely to lead to overtime work among enterprise employees (Fang, et al., \u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Norden and Ribeiro, \u003cspan citationid=\"CR33\" class=\"CitationRef\"\u003e2025\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eDigitalization can increase employees' number of working hours by facilitating the expansion of enterprise scale (Franco and Suppressa, \u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Zhang, et al., \u003cspan citationid=\"CR49\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). Digital technology provides firms with more efficient management tools and greater market reach (Du, et al., \u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Liu, et al., \u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). Through big data analysis, companies can better understand market demand, optimize production processes, and thus make more informed decisions about business expansion (Boerner, et al., \u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Wu, et al., \u003cspan citationid=\"CR42\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). This expansion often leads to increased workloads. Moreover, digitalization also heightens competition (Yan, et al., \u003cspan citationid=\"CR46\" class=\"CitationRef\"\u003e2024\u003c/span\u003e, Zhang, et al., \u003cspan citationid=\"CR49\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). To maintain a competitive edge in the digitally driven market, enterprises may push employees to work longer hours to ensure faster product development, more responsive customer service, and more efficient operations (He and Yi, \u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e2023\u003c/span\u003e, Liu, et al., \u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Shen, et al., \u003cspan citationid=\"CR37\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). This competitive pressure further contributes to the increase in employees' number of working hours as an enterprise expands under the influence of digitalization (Ar\u0026aacute;nega, et al., \u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Martindale and Lehdonvirta, \u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e2023\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eDigitalization can lead to an increase in employees' number of working hours by promoting corporate technological innovation. Digitalization offers enterprises abundant resources and tools for technological innovation (Andres, et al., \u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Chen, et al., \u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e2024\u003c/span\u003e, Yan, et al., \u003cspan citationid=\"CR45\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). Advanced digital research and development (R\u0026amp;D) platforms allow companies to conduct in-depth R\u0026amp;D more quickly (Wang and Wei, \u003cspan citationid=\"CR40\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Zheng, et al., \u003cspan citationid=\"CR53\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). Big data analytics helps in identifying market trends and customer needs precisely, which in turn guides targeted innovation (Magistretti, et al., \u003cspan citationid=\"CR27\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). When enterprises are engaged in technological innovation spurred by digitalization, they often face several situations that drive up employees' number of working hours (Mao, et al., \u003cspan citationid=\"CR29\" class=\"CitationRef\"\u003e2025\u003c/span\u003e, Neumann, \u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). During the process of technological innovation, new product or service development requires a high degree of concentration and continuous effort (Affandi, et al., \u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e2024\u003c/span\u003e, Ma and Lin, \u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). Employees in R\u0026amp;D departments, in particular, need to spend extra time testing, debugging, and optimizing new technologies. Furthermore, after the successful implementation of technological innovation, enterprises usually need to rapidly integrate new technologies into their operations (\u0026Ccedil;ela, et al., \u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e2024\u003c/span\u003e, Zhang, et al., \u003cspan citationid=\"CR49\" class=\"CitationRef\"\u003e2025\u003c/span\u003e). This integration phase also demands considerable time and effort from employees (Maione, et al., \u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e2024\u003c/span\u003e).

In the literature (Barentine, \u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e2022\u003c/span\u003e, Xuan and Wu, \u003cspan citationid=\"CR44\" class=\"CitationRef\"\u003e2023\u003c/span\u003e), the criterion for determining whether an enterprise is in a state of overtime work is based on comparison standards in terms of time and space dimensions. The reason for this is due to, unlike questionnaires, which are easily interfered with by factors such as subjective cognitive biases and personal willingness tendencies, satellite nighttime light data are obtained via remote sensing technology. Such technology can continuously collect information over a long time span and covers a vast geographical area. These characteristics are more in line with the needs of empirical research on large samples than are those of other approaches. The building method is as follows: on the one hand, the nighttime light brightness of listed company \u003cem\u003ei\u003c/em\u003e during legal holidays is taken as the comparison benchmark in the time dimension. When the nighttime light brightness of listed company \u003cem\u003ei\u003c/em\u003e is greater than that during legal holidays, the high light brightness may not be an inherent characteristic of the grid where the listed company is located but rather caused by the company's nighttime overtime work. On the other hand, the nighttime light brightness of the district or county where listed firm \u003cem\u003ei\u003c/em\u003e is located is used as the comparison benchmark in the spatial dimension. When the nighttime light brightness of listed company \u003cem\u003ei\u003c/em\u003e is greater than that of the district or county where it is located, it may also reflect the company's nighttime overtime work situation rather than the spillover effect generated by the surrounding infrastructure construction. In summary, when listed company \u003cem\u003ei\u003c/em\u003e meets both the time and spatial dimension criteria simultaneously, it is defined as being in a state of overtime work. The overtime work variable \u003cem\u003eOW\u003c/em\u003e\u003csub\u003e\u003cem\u003eit\u003c/em\u003e\u003c/sub\u003e of the listed company then counts the number of overtime work days of listed firm \u003cem\u003ei\u003c/em\u003e in year \u003cem\u003et\u003c/em\u003e.\u003c/p\u003e \u003cp\u003eThe explanatory variable is digitalization \u003cem\u003eDT\u003c/em\u003e\u003csub\u003e\u003cem\u003eit\u003c/em\u003e\u003c/sub\u003e.

The method of searching, matching, and summing keywords is adopted to depict the level of digitalization of enterprises.\u003c/p\u003e \u003cp\u003eThe control variable is \u003cem\u003eX\u003c/em\u003e\u003csub\u003e\u003cem\u003eit\u003c/em\u003e\u003c/sub\u003e, which incorporates key enterprise-level production and operation characteristics to account for potential confounding effects. These variables are selected on the basis of their theoretical relevance to both overtime work patterns and digitalization adoption. Specifically, the firm scale variable \u003cem\u003eScale\u003c/em\u003e is operationalized as the natural logarithm of total assets, which captures economies of scale and resource endowment effects; the capital structure variable \u003cem\u003eCS\u003c/em\u003e is measured by the total debt-to-assets ratio, reflecting financial leverage and risk management strategies; the capital intensity variable \u003cem\u003eCI\u003c/em\u003e is calculated as fixed assets per employee, representing the technology-intensive nature of production processes; the profitability variable \u003cem\u003eProfit\u003c/em\u003e is operationalized as return on assets, capturing the efficiency of asset utilization and overall financial performance; and the ownership concentration variable \u003cem\u003eOC\u003c/em\u003e is measured by the percentage of shares held by the largest shareholder, reflecting governance structures and agency costs.\u003c/p\u003e \u003cp\u003e \u003cb\u003eData sources.\u003c/b\u003e Overtime work indicators for listed firms are derived mostly from nighttime light data provided by the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor on the National Polar-orbiting Partnership (NPP) satellite in the United States. This data product has provided daily frequency nighttime light data since January 19, 2012. The Python programming language is used to analyze and process the relevant data. Specifically, through the longitude and latitude coordinate information of the office address disclosed in the annual report of the listed company, the company is mapped to the corresponding grid position with the help of a specific positioning algorithm, and then, the operation of reading the nighttime light brightness data of the grid where the enterprise is located is realized, providing data support for subsequent research and analysis. Digitalization data for listed companies are derived from annual reports of all A-share firms listed on the Shanghai and Shenzhen Stock Exchanges. A Python-based web crawler is employed to systematically collect and organize these reports, which are then processed using the Java-based \u003cem\u003ePDFbox\u003c/em\u003e library to extract full-text content. This forms the textual database for subsequent text mining analysis to identify digitalization-related keywords. Firm characteristic data are obtained from three primary sources\u0026mdash;the China Stock Market \u0026amp; Accounting Research (CSMAR) database, which is a core dataset for financial and operational metrics; the Wind Database, which includes supplementary data on market indices and corporate governance; and the China Research Data Service Platform (CNRDS), which includes additional macroeconomic and industry-level variables.

\u003cb\u003eBenchmark analysis.\u003c/b\u003e On the basis of the benchmark equation, a panel two-way fixed effects model is employed to control for individual and year fixed effects. In addition, considering the possible problem of heteroscedasticity, during the regression process, logarithmic transformation is carried out on variables with relatively large data fluctuations. The findings are reported in Table\u0026nbsp;\u003cspan refid=\"Tab2\" class=\"InternalRef\"\u003e2\u003c/span\u003e. In Column (1) of Table\u0026nbsp;\u003cspan refid=\"Tab2\" class=\"InternalRef\"\u003e2\u003c/span\u003e, the overtime work variable of listed companies is used as the dependent variable, and only the digitalization variable is introduced as the explanatory variable. Column (2) further introduces the production, operation, and management characteristics at the company level. Moreover, Columns (3) and (4) use overtime work on working days and overtime work on weekends, respectively, as the dependent variables to further examine the influence of digitalization on the overtime work of firms.\u003c/p\u003e \u003cp\u003eThe findings in Columns (1) and (2) of Table\u0026nbsp;\u003cspan refid=\"Tab2\" class=\"InternalRef\"\u003e2\u003c/span\u003e reveal that the coefficient of the digitalization variable is positive, indicating that the increased digitalization of listed companies increases employees' overtime work. A possible explanation for this is that digitalization usually brings about changes in business models and applications of new technologies. Moreover, digitalization may lead to adjustments in the company's organizational structure and the optimization of business processes. Employees need to adapt to these changes and continuously learn and become accustomed to new technologies and tools, thus resulting in an increase in employees' work burden and the need to work overtime to complete corresponding tasks. A comparison of the digital variables of listed companies in Columns (1) and (2) reveals that if the production and management characteristics of a company are not considered, then the impact of digitalization on employees' amount of overtime work will be overestimated. In addition, the findings in Columns (3) and (4) show that the digitalization variable is also positive, indicating that the digitalization of the company increases employees' amount of overtime work both on weekends and nonweekends.\u003c/p\u003e \u003cp\u003eThe control variables produce outcomes that are consistent with expectations. The regression coefficients for the firm scale are all significantly negative, showing that the larger the company scale is, the less overtime work. Large-scale companies usually have more complete management systems and resource allocations, enabling them to arrange work more reasonably, than do small-scale companies. The regression coefficients of capital intensity are all significantly positive, suggesting that the stronger the capital intensity is, the more serious the overtime work situation. Capital-intensive enterprises require more human input and technical support during the production or operation process, leading to increased levels of work pressure on employees and longer overtime hours. The regression coefficient for ownership concentration is negative, implying that a higher level of ownership concentration may diminish the likelihood of overtime work. The regression coefficients of capital structure and profitability are not significant in all columns, indicating that the impacts of capital structure and profitability on overtime work are not obvious within the sample interval.\u003c/p\u003e \u003cp\u003e \u003cdiv class=\"gridtable\"\u003e\u003ctable float=\"Yes\" id=\"Tab2\" border=\"1\"\u003e \u003ccaption language=\"En\"\u003e

Columns (1) and (2) of Table\u0026nbsp;\u003cspan refid=\"Tab3\" class=\"InternalRef\"\u003e3\u003c/span\u003e introduce the digital attention of the government and the public in the cities where listed firms are situated as instrumental variables. The government's digital attention is assessed using official work reports and the frequency of digital-related terms, whereas the Baidu search index is used to measure the public's digital attention. On the one hand, when the government in the region where a listed business is based is more concerned with digital concerns, the firm is more likely to gain government backing and advantageous policies if it actively participates in digitalization. On the other hand, when the public in the region where a listed business is based is more concerned with digital concerns and the firm actively pursues digitalization, then its corporate reputation and product impacts are more likely to be recognized and preferred by customers. As a result, if the government and the general public in the region where a listed firm is based pay more attention to digitalization, then the listed company is more likely to improve its digitalization efforts, achieving the correlation criterion. Furthermore, macroeconomic variables are less likely to be influenced by company overtime work, hence satisfying the condition of instrumental variable exogeneity. Columns (3) and (4) of Table\u0026nbsp;\u003cspan refid=\"Tab3\" class=\"InternalRef\"\u003e3\u003c/span\u003e introduce digitalization at the regional and industry levels, respectively, as instrumental variables. On the basis of the digitalization situations of listed companies in the respective cities and industries, the digitalization situations of the cities and industries where the listed companies are located are aggregated, and the digitalization situation of the company itself is deducted. The results in Table\u0026nbsp;\u003cspan refid=\"Tab3\" class=\"InternalRef\"\u003e3\u003c/span\u003e reveal that when endogeneity is controlled for, all of the coefficients of digitalization are considerably positive, implying that digitalization will increase the amount of enterprise employee overtime. In addition, weak instrumental variable tests and overidentification tests are used for the instrumental variables. The test findings reject the null hypothesis, demonstrating the efficiency of the instrumental variables.\u003c/p\u003e \u003cp\u003e \u003cdiv class=\"gridtable\"\u003e\u003ctable float=\"Yes\"

First, digital development leads to the expansion of the enterprise's business scale and business transformation, thereby generating a greater workload. The scale expansion effect prompts employees to work overtime. Second, with the implementation of the enterprise's digitalization strategy, the enterprise's R\u0026amp;D and innovation activities tend to increase. Moreover, R\u0026amp;D investment has obvious characteristics of skill bias, which generate greater demand for highly skilled labor in the enterprise. Through the technological innovation effect, this situation prompts employees to work overtime. On this basis, the market expansion mechanism and technological innovation mechanism are tested. The market expansion mechanism is assessed according to the rate of increase in operating revenue and inventory turnover, whereas the technical innovation mechanism is measured by the number of digital patent applications and R\u0026amp;D workers.\u003c/p\u003e \u003cp\u003eThe findings are shown in Table\u0026nbsp;\u003cspan refid=\"Tab4\" class=\"InternalRef\"\u003e4\u003c/span\u003e. Columns (1) and (2) show the market expansion mechanism. The impacts of digitalization on a company's revenue growth and inventory turnover are significantly positive. That is, digitalization usually leads to the expansion of the market scale. Employees need to continuously learn and adapt to new businesses, which increases their work burden and makes them need to work overtime to complete corresponding tasks. Columns (3) and (4) report the technological innovation mechanism. The impacts of digitalization on the numbers of patent applications and R\u0026amp;D personnel of enterprises are significantly positive. That is, intelligent development can promote innovative collaboration and knowledge sharing and generate greater demand for highly skilled labor. Compared with routine and repetitive low-skilled jobs, highly skilled jobs are more likely to involve overtime work.\u003c/p\u003e \u003cp\u003e \u003cdiv class=\"gridtable\"\u003e\u003ctable

economic activities, the digital attitude of a firm's managers directly affects the effectiveness of its digitalization. The annual report texts of the management issued by the company contain incremental information and can reflect the details, logic, and evidence that cannot be reflected in quantitative information. When the digital attitude of the company's management is more positive, it presents positive expectations for the firm's digitalization in the annual report. Therefore, this article takes the annual report texts of the management of listed firms as the carrier. The sentiment analysis dictionary of \u003cem\u003eCNKI HowNet\u003c/em\u003e differentiates positive and negative emotion words, automatically segments texts using Python's Chinese word segmentation package, and counts word frequencies. Then, the indicators of the proportion of digital positive word frequencies and the proportion of digital negative word frequencies of listed companies are constructed.\u003c/p\u003e \u003cp\u003eThe findings are reported in Table\u0026nbsp;\u003cspan refid=\"Tab6\" class=\"InternalRef\"\u003e6\u003c/span\u003e. When the degree of digitalization of listed companies is fixed, if the management of a company holds a more positive attitude toward digitalization, then the extent to which digitalization leads to an increase in employees' amount of overtime work in listed companies will be weakened. When management holds a positive digital attitude, during the digitalization process, the enterprise pays more attention to improving efficiency through reasonable planning and efficient process design rather than simply relying on increasing employees' number of working hours. For listed companies whose management holds a negative attitude toward digitalization, the extent to which digitalization leads to an increase in employees' amount of overtime work in listed companies will be strengthened. A negative digital attitude may manifest as a company's lack of clear strategies and plans during the digitalization process, resulting in chaos and inefficiency. As a result, employees need to spend more time solving these problems, thus increasing their number of overtime hours.\u003c/p\u003e \u003cp\u003e \u003cdiv class=\"gridtable\"\u003e\u003ctable

mechanism of the impact of digitalization on the amount of overtime work of listed companies by using a microeconometric model and further discusses whether the resulting overtime work can be compensated with income. The results show that with the digitalization of listed companies, employees' amount of overtime work will increase to a certain extent, and this conclusion still holds after controlling for the endogeneity problem. The analysis of the mechanism shows that digitalization affects employees' amount of overtime work through the market expansion mechanism and the technological innovation mechanism. Further discussion shows that the digitalization of listed companies can increase the total income and average salary of employees and that overtime work is an important reason for the increase in income compensation brought about by digitalization. In addition, when the degree of digitalization of listed companies is certain, if the management of the company holds a positive attitude toward digitalization, then it can reduce the amount of employees' overtime work caused by digitalization. If the management of a company holds a negative attitude toward digitalization, then it can increase the amount of employees' overtime work caused by digitalization. On the basis of the research findings, this study proposes the below policy suggestions.\u003c/p\u003e \u003cp\u003eFirst, governments advancing enterprise digitalization must enact regulatory frameworks for monitoring labor practices. While acknowledging the productivity benefits of digitalization, mandatory measures should prevent exploitative overtime as a digitalization driver. Legislative initiatives must define the maximum number of working hours during digital transitions, curbing corporate tendencies to prioritize transformation velocity over workforce well-being. Second, governments must implement sector-specific regulations that steer corporate strategies through industrial policies. This curbs innovation arbitrage, where market share competition drives exploitative overtime practices. Legislative frameworks should establish legally binding overtime thresholds with premium compensation during R\u0026amp;D cycles, mandating phased innovation roadmaps aligned with workforce sustainability metrics. Enterprises are obligated to synchronize project timelines with human resource capacities and implement task distribution algorithms to prevent workload clustering. Finally, the issue of excessive overtime in digital transformation requires structural adjustment through organizational culture building. Governments should employ policy incentives and public advocacy to guide enterprises in integrating humanistic considerations into digitalization strategies. Enterprises must cultivate digital organizational cultures that emphasize bidirectional empowerment. This stratified governance model enhances organizational resilience, achieving synergistic evolution between technological adoption and labor rights protection.\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eData availability\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThe data that support the findings of this study are available within the supplementary files of this article.

This study uses nighttime satellite light data to examine the impact and mechanism of the digitalization of listed companies on employees' amount of overtime work and further discusses the issue of income compensation for such work. The results show that digitalization increases employees' amount of overtime work through the market expansion mechanism and the technological innovation mechanism. In addition, digitalization can increase the total revenue and average wage of enterprises; that is, there is an income compensation effect for overtime work. This study also reveals that listed companies' more positive attitudes toward digitalization can effectively weaken the overtime work problem caused by digitalization. This study advocates optimizing the operational efficiency of digitalization while safeguarding employee rights, thus fostering sustainable synergy between organizations and workforces during digital transformation.","manuscriptTitle":"A double-edged sword: Digitalization of listed companies and employee overtime","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2026-04-03 00:27:23","doi":"10.21203/rs.3.rs-9036465/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"editorInvitedReview","content":"","date":"2026-04-27T12:14:23+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"194374138381925472685865243539925678298","date":"2026-04-02T07:43:42+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"189776814490398474458696491515122575373","date":"2026-03-31T07:51:28+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2026-03-31T07:21:49+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2026-03-31T07:20:19+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2026-03-31T06:57:05+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2026-03-11T12:53:03+00:00","index":"","fulltext":""},{"type":"submitted","content":"Humanities and Social Sciences Communications","date":"2026-03-11T08:40:32+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
