摘要

Equalizing basic public services (BPS) is essential to achieve common prosperity. In the context of new urbanization, there has been less discussion on how urban spatial structure affects the BPS equalization. This study analyzes the theoretical mechanisms by which urban polycentric structure affects the BPS equalization from agglomeration economies and urban amenity perspectives. Based on LandScan data, exploratory spatial data analysis is applied to measure the polycentric structure of urban population, and the BPS equalization within the city is measured using district and county data. The study results show that the urban polycentric structure significantly promotes the BPS equalization. Mechanism tests show that the urban polycentric structure promotes equalizing BPS by strengthening the effect of agglomeration economies and improving urban amenities. Furthermore, the polycentric distribution dominated by a main center, the expansion of the urban scale, and the improvement of transportation facilities are conducive to strengthening the BPS equalization effect in the urban polycentric structure. Moreover, there is an inverted U-shaped nonlinear relationship between the number of urban subcenters and the BPS equalization. A smaller dispersion and a higher degree of balance among urban subcenters will lead to a higher level of BPS equalization. In the future, the government should maintain the leading position of the urban main center and strive to establish a compact, balanced, and appropriate urban polycentric development model.
