Abstract: The development of China’s social work, pushed by the government, has become a strong measure for the innovation of government management system. The rural migrant workers, the key social group involved in China’s urbanization, have come to be an important group of clients to whom social workers extend services. Any social worker serving the rural migrant workers needs to respond to two basic questions: how to conduct social work services and attain the best results when working with rural migrant workers, and how to clarify the position and orientation for the professional development of social workers in the process of conducting social work services. However, the current traditional, static and direct service of social workers—case, group and communitybased—cannot offer a satisfactory answer within the service system. From a dynamic perspective, social work is a profession to modify and improve the rural migrant workers’ supportive relationship. The realization of this new dynamic relationship service depends upon utilization of a new technique called social work project, aiming at digging and utilizing the resources of the rural migrant workers’ supportive network and attaining the best results.

Key words: rural migrant workers; social work; direct service; dynamic relationship service
