中文摘要：

本文基于2010—2014年中国286个城市公共服务支出数据，采用空间面板模型，就人口流动规模、财政自主权等关键因素，对各城市公共服务支出的影响进行了识别和相应政策讨论。结果表明：（1）流动人口规模越大越会显著降低人均普通教育经费支出、社会保障和就业支出、医疗卫生支出，地区层面的影响呈现出明显的异质性。（2）财政自主性的提高并非会促进人均公共服务支出水平的增加，对超大城市、特大城市、大城市的影响主要是通过提升公共服务支出的使用效率来实现，而中小城市公共服务建设主要依靠转移支付，地方政府更偏好于基础设施等“硬公共品”的支出。

英文摘要：

Based on the data of 286 urban public service expenditure in China from 2010 to 2014, this paper employs spatial panel model to estimate the impact of the key factors such as the scale of migrant, financial autonomy etc. on urban public service expenditure , and discuss pertinent policies. The results find ： （ 1 ） the increasing scale of the migrant will significantly reduce the per capita expenditure on general education, social security and employment and medical health,this impacts existing a significant regional heterogeneity;（ 2 ）The increase of financial autonomy isn＇t equal to improve the level of per capita public service expenditure, and the above impact on the megacities, large cities and big cities mainly rely on the efficiency of public service expenditure using, but the construction of public services in small and medium-sized cities basically depends on transfer payments, moreover, local governments prefer to the expenditure of infrastructure and other ＂hard public goods＂.
