In the context of population ageing, this study utilizes data from the China Longitudinal Aging Social Survey (CLASS) and the China Health and Retirement Longitudinal Study (CHARLS) to construct a measurement indicator system and demarcate alert-boundary zones. From national, regional, and urban-rural perspectives, we systematically investigate supply-demand matching levels and trends of China's healthy ageing services. The results show that the supply-demand matching levels of healthy ageing services in China have gradually improved yet remain predominantly within alert-boundary zones. High demand that exceeds insufficient supply constitutes the primary mismatch driver. The imbalances primarily manifest in long-term care, free physical examinations, home-based medical visits/medication delivery, and health management services. Moreover, there is significant regional and urban-rural heterogeneity in the supply-demand imbalances of healthy ageing services, which faces the dual challenges of high-level imbalances and low-level matching. Less developed regions exhibit marked deviations between actual and potential demands among older people. Therefore, the supply of healthy ageing services should be strengthened through targeted interventions addressing supply-demand imbalances, and initiatives should be taken to promote regionally balanced development of healthy ageing services.
