Abstract: The analysis of existing mixed community integration cannot only start from the inside of the community, because the supply of community public services will also affect the community integration. According to the connotation of community integration, the mixed community integration is divided into four dimensions:community interaction, community norms, community role models and community attachment. Then the theoretical assumptions and relationship models of the four dimensions of public service content, public service efficiency and public service subject influence are put forward based on literature research. Based on the data analysis of four communities in Chengdu, it is concluded that community interaction, community norms, community role models and community attachment are all affected by public service content. The efficiency of public service and the main body of public service also have obvious influence on community interaction and community norms. However, the efficiency of public service has no obvious influence on community role models and community attachment, and the public service body has no obvious influence on community attachment. Finally, relevant recommendations on integration of existing mixed communities were made.

Key words: existing mixed communities, provision of public services, integration, influence factors
