Description
The escalation of urban social spatial polarization heightened demands for public resource planning, particularly in achieving a balance both on social equity and justice performance. The evaluation of social performance within the realm of urban planning has undergone a progression from regional equality to social equality, and ultimately to social justice. The principle of social equity is predicated on the assumption that all social groups possess identical abilities and needs, thereby advocating for the equitable distribution of public resources. Conversely, the principle of social justice emphasizes the disparities in capabilities and needs among diverse groups, asserting that public resources should be preferentially allocated to disadvantaged populations to realize substantive equality.
This study employs the distribution of streets’ Green View Index (GVI) in the central urban area of Shanghai in 2022 as a case study to construct a framework for evaluating the social performance of street greening distribution. In assessing social equity performance, the Gini coefficient is utilized to gauge overall fairness, while the Lorenz curve facilitates an analysis of the congruence between population distribution and GVI. Additionally, location entropy is employed to elucidate the spatial configuration. In evaluating social justice performance, a share index is introduced to ascertain whether the green visibility rates accessible to specific age and income groups meet or exceed the average level of the resident population, supplemented by location entropy analysis to examine spatial distribution characteristics.
The findings reveal that the social equity performance of street GVI in Shanghai's central urban area resides within a relatively acceptable range, reflecting the positive outcomes of recent urban greening initiatives. However, while social justice performance is generally reasonable, it does not adequately favor disadvantaged groups. Furthermore, the spatial analysis of social equity and justice performance uncovers a notable degree of "spatial mismatch" between green visibility rates and population distribution, indicating that public resource allocation necessitates further optimization to effectively achieve the dual objectives of social equity and social justice. Consequently, this study advocates for the strategic optimization of greening resource distribution in planning, with a focus on areas predominantly inhabited by disadvantaged groups, while also emphasizing the importance of dynamic monitoring and adjustment of spatial alignment to systematically address issues of fairness and justice in public resource allocation.
