This study examined regional disparities and spatiotemporal dynamics in the allocation of Practicing (Assistant) Physicians across northern versus southern China, using data from 31 provincial-level administrative regions from 2012 to 2022 and assessing total supply, per-capita availability, and spatial accessibility. It found that physician numbers and growth were higher in southern China between 2012 and 2022, and HRDI favored the south, but southern China remained disadvantaged when measured as physicians per 1,000 population, with interregional inequity worsening over time (Gini increased from 0.350 to 0.373). Within-region inequality showed divergent patterns and spatial autocorrelation analyses identified north–south clustering for physicians per 1,000 population and an east–west pattern for HRDI. The paper is a preprint and was not peer reviewed, limiting the strength of conclusions. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract Objective: This study aims to examine regional disparities and spatiotemporal dynamics in the allocation of Practicing (Assistant) Physicians between northern and southern China, using a north–south division that captures pronounced geographic and population heterogeneity. Methods: Based on data on Practicing (Assistant) Physicians from 31 provincial-level administrative regions in China from 2012 to 2022, this study analyzes regional differences and their dynamic evolution from three dimensions: total supply, per capita availability, and spatial accessibility. The number of Practicing (Assistant) Physicians per 1,000 population and the Health Resource Density Index (HRDI) were employed as key indicators. Results: From 2012 to 2022, the number of Practicing (Assistant) Physicians in southern China increased from 1.424 million (54.4%, 1.80 physicians per 1,000 population) to 2.511 million (56.6%, 2.99 physicians per 1,000 population), while the corresponding figures in northern China rose from 1.191 million (45.6%, 2.11 physicians per 1,000 population) to 1.924 million (43.4%, 3.39 physicians per 1,000 population). The growth rate of Practicing (Assistant) Physicians was notably higher in the southern region than in the northern region. In terms of allocation equity, the Gini coefficient between the northern and southern regions increased from 0.350 in 2012 to 0.373 in 2021. Within-region inequality exhibited divergent trends: the Gini coefficient in the northern region rose from 0.358 to 0.391, whereas that in the southern region declined from 0.327 to 0.311. Moreover, the Theil T index was significantly higher in the southern region, while the Theil L index was slightly higher in the northern region. Spatial autocorrelation analysis further revealed distinct spatial patterns across indicators. The distribution of Practicing (Assistant) Physicians per 1,000 population showed pronounced north–south clustering, with hotspot areas mainly located in northern China and cold spots concentrated in southern China. In contrast, the HRDI exhibited a clear east–west pattern, with hotspots clustered in eastern China and cold spots in western China. Conclusion: Southern China outperformed northern China in terms of the total number, growth rate, and HRDI of Practicing (Assistant) Physicians, with the interregional gap showing a widening trend over time; however, the southern region remained disadvantaged in terms of physicians per 1,000 population. Allocation disparities in southern China were more pronounced across provinces with different levels of economic development, whereas in northern China, inequities were primarily associated with variations in population density. The spatial distribution of Practicing (Assistant) Physicians in China showed distinct agglomeration patterns across different indicators. Both population equity and spatial accessibility must be considered, as a single indicator cannot fully reflect resource allocation situation. Targeted resource regulation strategies should be developed to address these varying dimensions.
