The index system includes three parts：the level of investment and development，the level of service and people’s livelihood，and the level of equity and security，involving many public investment in the social sector，such as social services，people’s livelihood，social equity，social security，there are altogether 14 specific indicators. The results of comprehensive evaluation and annual comparison of the social management level in key cities show that the level of social management is not synchronized with its economic development level，and the level of people’s livelihood services is also not synchronized with its economic development level. Although urban investment in social services and people’s livelihood is increasing，it still cannot fully meet the needs of urban development. Despite the continuous improvement of living standards of urban and rural residents，the development gap between different cities，urban and rural areas is still large，the relationship between supply and demand of public services remains strained，and the allocation of resources is unbalanced. The problem of social equity is still prominent，and the level of social assistance and security needs to be continuously improved. In a word，the evaluation results of urban social management level fully reflect that the development of social investment and development，social services and people’s livelihood，social equity and security are not only underdeveloped，but also unbalanced between regions，urban and rural areas. In the course of development，must continue to improve the ability and level of people’s livelihood services，constantly optimize the structure and deepen reform to promote equitable and balanced development，encourage innovative practices in social governance and build a community of social governance. Continually，continue to advance the modernization of social governance capacity and system，improve the quality and efficiency of social development，and eliminate the inequities and imbalances in social development，so as to provide a sound social foundation and guarantee for improving people’s well-being and promoting all-round human development.
