Under the background of the two-way integration of information technology and elderly care services, the development of community-based smart elderly care services is in the ascendant. Optimizing the supply of community-based smart elderly care services is a key link in building an overall smart elderly care service layout, which is of great value in improving the elderly care service system with Chinese characteristics. Using the multi-case study method, the typical community-based smart elderly care service examples in Beijing, Tianjin and other places in China were investigated. It is found that the community-based smart elderly care service model is an organic system with an organic system of infrastructure layer, data layer, application service layer, and presentation layer, where each layer contains specific structure and function. Its service process includes six closed links: work order circulation, work order generation, supervision and evaluation, charge accounting, statistical analysis and service adjustment. Based on the service process deduction, the responsibility network of the main body of community smart elderly care service providers are proposed, which consists of the interaction of the elderly, information technology systems, household systems, public sector systems and social systems. This responsibility network is equipped with the functional integration of community-based smart elderly care services, which contributes to the realization of family elderly care function, government elderly care function and socialized elderly care function. At present, there are difficulties in development of community smart elderly care services, including multiple realistic constraints such as the immaturity of the responsibility network from the supplying body, limited resource links of information platform as the hub of the responsibility network, and insufficient multi-dimensional extension of the smart services. Based on the three-dimensional analysis framework of “supply target—supply subject—supply tool”, the systematic construction of the supply mechanism of community smart elderly care services was discussed. The supply objective dimension focuses on reducing transaction costs, the supply subject dimension focuses on multiple collaborative empowerments, and the supply tool dimension focuses on realizing multiple tools to boost.
