With the aggravation of the aging problem and the decline of family care, community-provided care service came into being driven by multiple factors. The key elements to promote the setting of the policy agenda are the importance attached by the state to national habits, the concern of the policy community, the prominence of social pension issues and the issuance of national guidance. The top-down government policy guidance and the positive response of the local government are the two driving forces to promote the implementation of the policy. Insufficient supply, low quality, and contradiction between supply and demand are prominent problems in the current community elderly care service policy. Deeply digging into the causes, it is found that the large gap between the current charging level of community elderly care service and the ability to pay is the key to the problem. By constructing a policy-driven model in three dimensions, including policy agenda, policy action and policy evaluation, this paper explores the generation logic and operating status of community pension service supply policies. Based on this, it is proposed that the provision of community elderly care service for the disabled elderly should continue to play the role of the government to provide high-quality and professional community elderly care service, and improve the consumption conditions of disabled elderly people.
