英文摘要：

The development of megacities is faced with many risks and pressure. The community has functions of providing public services,coordinating social relations,promoting social integration and coping with social risks. According to the investigation of 10 communities in Tianjin,it is found that community governance functions have not been fully realized due to the restriction of the administrative,financial and some technical factors. Therefore,the megacities need to innovate in conceptions of community construction,improve the urban governance structure,expand the sources of financial investment,and strengthen the system supply.
