Abstract: In this paper,the author reflected the inclination of overprofessionalization in the development of social work and brought about the idea of conducting social work in a multicooperation context. Then, taking the SD Center case as an example, this article illustrates “Conducting Social Work in a Multicooperation Context” from such four aspects as the definition, the involved party, the type and the structure of the mechanism. After indepth research, the author drew four conclusions. First, the definition of cooperation is various. Cooperation is not only a cooperative action towards a specific goal, but also a series of work, including resource integration and service network establishment. Second, the involved party of cooperation is varied. It consists of individual, organization, institution and corporation. Third, the type of cooperation is diversified. We have cooperation between different parties in one discipline and have transdisciplinary cooperation. We have formal and informal cooperation. We have cooperation inside and outside the community. Fourth, the structure of the mechanism of cooperation is intricate. While we can build a formal cooperative relationship, the formal cooperation and informal cooperation can be converted to one another. Also, we can construct a longterm and stable interactive relationship.

Key words: Multicooperation, the Involved Party of Cooperation, the Type of Cooperation, Constructing Cooperative Relationship
