As the income increasing and acceleration of urban integration，floating population is paying more and more attention on urban public service. Education，medical care，traffic condition and other urban public service are becoming critical features that affect floating population’s decision on staying or leaving urban areas. This section summarized and clarified relative studies on urban public service and floating population’s urban integration. Then，on base of prefectural panel data during 2001 to 2016，using SYS GMM method，we proved that public service such as medical care，traffic condition and internet is significant positive for the growth of urban floating population. Thus，urban public service should be effectively strengthened and provided to all residents if urban governments want to attract more population.
