With the accelerated approaching of the aging society in China, the role of Community Home Care model for the elderly has become increasingly prominent. According to the principle of multi-welfareism on the function-sharing among subjects, this paper analyzes the status of functional conflicts among the multi-subjects concerned (government-society-market-family) in the Chinese community-based aged care services. Based on this, from the perspective of multi-subject responsibility sharing, the development path of the four subjects is interdependent: the government is required to achieve decentralization in the guidance of the community home care service market, and give full play to the professional expertise of social organizations, and adhere to the market in service configuration, cultivating the active consumption consciousness of the elderly and their families.In short, the cultivation of the four-part benign interaction and shared home-based care service market depends on the classification and management of service demand and the cultivation of a fully competitive aged-service market.
