With the deepening trend of population aging and the increasing diversification of elderly care models, enhancing the well-being of older adults has become a central focus in both research and practice within the social care sector, building upon the foundation of ensuring their material livelihood and spiritual experience. This paper systematically analyzes the core healthy elderly care needs of different types of older adults, constructs a multi-level integrated medical and elderly care service system, and optimizes the multi-level, multi-format community-based care service model from the perspective of well-being enhancement. This research not only contributes to the systematization and standardization of elderly care services but also holds significant importance for driving the development of related industries, absorbing more social employment, and further implementing the national strategy for actively addressing population aging.
