Description

As the most developed urban agglomeration in China, the core area of the Yangtze River Delta has an overall urban - rural integration level far exceeding that of other urban agglomerations in the country and is the most urbanized one. Traditionally, people have often focused on the accessibility of public service facilities in urban areas, while paying less attention to that in rural areas. As a disadvantaged area, the accessibility of public service facilities in rural areas is crucial for regional equity, especially in terms of spatial equity.
This study focuses on exploring the spatial equity characteristics of three types of social infrastructure in the rural areas of the core area of the Yangtze River Delta, namely public service facilities such as bus stops, primary schools, and healthcare. By using POI data from Amap in 2014，2018 and 2022, WorldPop population distribution data, and Open Street Map road network data, we conduct an in - depth research on the fairness differences in the spatial and population accessibility of these three types of basic public service facilities at different times.
The research findings indicate that with the advancement of China's new urbanization and integration strategies, significant differences still exist in the accessibility of public service facilities in rural areas of different regions within the core area of the Yangtze River Delta, ranging from 20 minutes to 2 hours. Multiple infrastructures show greater regional disparities. Approximately 20% of rural residents cannot access any infrastructure within 15 minutes, while over 60% of rural residents can access all infrastructure within 15 minutes. The accessibility of most public service facilities is narrowing, but the accessibility of primary schools is expanding. Among the three types of public service facilities, the accessibility of healthcare facilities is higher than that of bus stops and primary schools. Our results clearly disclose the quantified accessibility gap of public service facilities among different rural areas within the urban agglomeration, highlighting the spatial equity issues, and emphasize the necessity of social infrastructure planning to address such gaps.
