This paper constructs the public service satisfaction index，and analyzes the public service satisfaction in seven cities based on the index. The results show that the overall satisfaction of public service in seven cities has not reached a satisfactory level. Among them，Chongqing and Hangzhou share the first place，with the four first-tier cities ranked lower. In terms of fields，developmental public services，such as public safety，ecological environment and social services，are ranked at the top，while social security services，such as housing services，medical and health services and old-age services，are ranked at the bottom. In this paper，hierarchical linear model is used to analyze the influence of individual and city factors on public service satisfaction. At the city level，the high level of city economy，the large financial investment in public service and the good effect of public service are positively correlated with the satisfaction of public service. At the individual level，the elderly，rural residents，people with houses，party and government organs and institutions，and groups with high incomes have higher satisfaction with public services. Based on the above analysis，this paper puts forward five countermeasures and Suggestions to improve public service satisfaction.
