Abstract: In the current social background of accelerating aging growth in China, the article conducts in-depth research on the balance of supply and demand in the field of elderly care services, hoping to provide a reference for further reforming the supply side of elderly care services and improving the level of elderly care services. On the basis of defining the main body of the elderly care supply and demand, the intermediary variable of the elderly care service policy is introduced to build a framework and model for matching the supply and demand of elderly care services, and then through the collection of citizens’elderly care needs in Baidu Knows, Zhihu and other online platforms and the review of China's pension policy from 2005-2019, an empirical research was conducted on the matching between the demand for pension services and policy supply. The results show that the matching model can better measure the level of supply and demand of elderly care services, and unearth the problems of insufficient policy supply in the elderly care service field, emphasizing material over spirit, and single service supply. Measures such as adopting precise classification of services, strengthening communication between supplier and demand side, and diversifying the service systems, are proposed to improve the supply of elderly care services.
