However, current research predominantly focuses on the quantitative distribution of spatial resources, paying inadequate attention to its effects on service facility quality and community empowerment. Key findings reveal distinct patterns in green space accessibility and quality between Portland and Chengdu. In Portland, green space access is unequal between classes. This inequality is connected to racial segregation. Conversely, Chengdu’s city growth has caused less green space in its old urban centers. Regarding service quality, Portland exhibits maintenance investment disparities between old and new districts, with an emphasis on standardized eco-technologies. In contrast, Chengdu prioritizes smart city initiatives and the integration of cultural elements into its green spaces. On the dimension of entitlement, Portland implicitly establishes participation thresholds that lead to exclusionary outcomes. By comparison, Chengdu requires stronger regulatory enforcement and accountability for non-compliance. This study proposes an innovative three-dimensional assessment model. It extends the application of spatial justice theory to inclusive urban regeneration and provides empirical support for optimizing green space in high-density urban areas. Moreover, the model also offers international insights and methodological references for eco-city construction and related policy formulation.
