Social service organizations have developed quickly as a result of the Chinese government outsourcing services in recent years. The policy of government outsourcing services has been successful in developed countries and is transferred to China mainland. However, there are critical differences between China and these areas. The precondition for success in outsourcing services in Western countries is that the nonprofit organizations are relatively independent and strong. In China, however, the relationship between the government and social organizations is fuzzy, and social organizations are still quite weak. Thus, the effectiveness of social service in the West depends on collaboration between the government and nonprofit organizations (NPOs), during which the boundaries are eliminated and partnership is built. The preexistent boundaries make sure that the government and NPOs could cooperate independently and equally. In China, boundaries should be produced first to assure the effectiveness of the government purchases of social services. This paper focuses on the family integrated service centers in Guangzhou and analyzes the production of boundaries in the process of service delivery strategies. It aims to respond to the partnership theory and theoretical issues regarding the development of social organizations in China.
