Description
The quality of urban public service facilities is of utmost importance for the quality of citizens' social life and the economic development of Shanghai. However, most existing research has been centered on the layout and accessibility analysis of a single type of facility, lacking a comprehensive exploration of the overall equity of various convenience and public service facilities within the 15 - minute living circle. Additionally, few studies have delved into the spatial determinants behind the unequal distribution of facilities.
To address these research gaps, this study innovatively conducts a systematic assessment of the equity of diverse convenience and public service facilities within the 15 - minute living circle in Shanghai, and analyzes their intricate non - linear associations with the built environment.
In terms of research methods, the gridded Gaussian two - step floating catchment area method is adopted to analyze the 15 - minute accessibility of both single - type and multiple - type facilities. Subsequently, the Moran's Index and geographical detector are utilized to unveil the spatial differentiation patterns and the spatial factors influencing the accessibility of different facilities.
The research results reveal significant disparities in the accessibility of public facilities within the living circles in Shanghai, presenting a core - periphery pattern and multi - center spatial characteristics, which reflects remarkable spatial heterogeneity. Meanwhile, housing prices, functional mix, and public transportation accessibility have a substantial positive impact on the equity of facilities. The influence of the distance from the urban CBD and road connectivity shows alternating positive and negative trends within different threshold ranges.
These findings imply that spatial deprivation in Shanghai may occur across different types of facilities and be affected by various spatial factors. This study constructs an equity evaluation system for the 15 - minute living circle of multiple facility types, exposes the spatial deprivation phenomenon underlying the unequal distribution of facilities, provides empirical evidence for promoting urban spatial justice and social equity in Shanghai, and contributes to enhancing the overall quality of life and well - being of Shanghai's residents.
