The "Community Inclusion" project in S City P District is the result of government and social cooperation which built on the basis of demand fit. Remarkable results achieved in pre-project confirmed the initial success of "government and social cooperation" in the United Front field. However, with the gradual progress of the project, the project gradually appeared operation dilemma, a phenomenon called "involution": purchasing form is not uniform; project objectives bold aesthetic; accountability relationship is not clear; social workers in the United Front field are left in an ambiguous position; the project is undertaken by the lack of professional space; the wastage rate of social workers in the United Front field is higher and a stable professional team is difficult to maintain. Through further analysis, we find that the dilemma of government and social cooperation stems from the "three deficiencies": lack of knowledge of grassroots government departments; lack of credibility of social organization; lack of social work personnel and professional space. Government and community organizations need to make joint efforts in order to build a healthy, positive cooperative interaction.
