构建了衡量城市公共服务供给水平与空间格局的指标体系，并借助空间杜宾模型，分析城市公共服务供给水平的空间效应以及影响因素。研究发现：（1）在时间维度上，城市公共服务供给水平总体上呈现出稳定增长态势；在空间格局上，多数城市公共服务供给水平的区间都处于较低和最低水平，且存在差异性。（2）城市公共服务供给水平呈现出明显的全局与局部空间自相关，且空间俱乐部的趋同特征明显。（3）空间杜宾模型回归结果表明，城市公共服务供给水平在空间上存在正向溢出效应；城市政府治理、人口密度、人口城镇化率、经济发展水平和产业结构对本地区城市公共服务供给水平产生正向作用，其中人口密度产生的影响最大，可以使本地区城市公共服务供给水平上升11.5%。而人口密度和人口城镇化率对周围城市公共服务供给水平具有显著的负向作用，会造成周围城市公共服务供给水平分别下降25.1%和9.44%。
The level of urban public service supply is an important factor affecting the healthy and stable development of a city, and its good spatial pattern helps to rationally allocate public resources and promote win-win development of urban cooperation. However, at present, the research on the spatial pattern and influencing factors of China's urban public service supply level is still insufficient. Therefore, this paper attempts to construct an index system to measure the level and spatial pattern of urban public service supply, and analyzes the spatial effect and influencing factors of urban public service supply level with the help of the spatial Durbin model. The research shows that: (1) From the perspective of time, the level of public service supply in Chinese cities generally shows a steady growth trend; from the perspective of spatial pattern, the level range of public service supply in most cities is at the lower and lowest levels, and there are differences. (2) The level of public service supply in Chinese cities shows obvious global and local spatial autocorrelation, and the convergence characteristics of spatial clubs are obvious. (3) The regression results of the spatial Durbin model show that the level of urban public service supply has a positive spillover effect in space; urban government governance capacity, population density, population urbanization rate, economic development level and industrial structure have a positive effect on cities in the region The level of public service supply, of which population density has the greatest impact, can increase the level of urban public service supply in the region by 11.5%. The population density and population urbanization rate have a significant negative effect on the supply level of public services in surrounding cities, which will cause the supply level of public services in surrounding cities to drop by 25.1% and 9.44%, respectively.
