【摘要】 以我国246个地级及以上城市为研究对象，采用城市标度律评价城市人口规模与基本公共服务支出的适配程度及其地区差异。研究发现：我国基本公共服务支出规模与结构均与城市人口规模呈现显著的非线性标度关系，且基本公共服务支出增加率小于人口规模增加率。从基本公共服务支出结构来看，除科学技术支出与城乡社区支出外，其他支出的增加率均小于人口规模增加率。总体来看，基本公共服务支出规模修正指标存在空间异质性，组内差异是其主要来源。大城市基本公共服务支出能较好地适配人口规模，超大特大城市及中小城市基本公共服务投入相较于其人口规模存在一定程度的不经济性。研究结论可为优化不同人口规模城市基本公共服务供给提供新的思路。更多还原

【Abstract】 Using data of 246 cities in China, this paper evaluated the degree of adaptation and regional differences between urban population size and basic public service expenditure according to the urban scale law. Research found that the scale and structure of basic public service expenditure in China had a significant nonlinear scaling relationship with urban population size, with the growth rate of basic public service expenditure being lower than that of population size. Based on the structure of basic public service expenditure, the growth rate of other expenditures was lower than that of populations, except for growth rate of science and technology and that of urban and rural community expenditures. There was spatial heterogeneity in the scale correction indicators of basic public service expenditure in China, with intra group differences being the main source. The expenditure on basic public services in large cities could better adapt to the population size, and there was a certain degree of diseconomy in the investment in basic public services of super large and small cities for population size. This paper could provide new ideas for optimizing the supply of basic public services in cities with different population sizes.更多还原
