Abstract: With the intensification of China's aging society, the demand for elderly care services is growing, especially in mega-cities like Shanghai. This study takes the Caoyangxincun neighborhood in Putuo district, Shanghai, as a case study to explore how to optimize the spatial layout of elderly care facilities to meet the needs of the community's elderly population under the guidance of the“15-minute community life circle”concept. Based on the principle of supply and demand matching, the study analyzes elderly population data, the distribution of elderly care facilities, and their service coverage radii to assess the accessibility and supply-demand matching of community elderly care facilities. The results show that although the distribution of elderly care facilities in Caoyangxincun neighborhood is generally uniform and relatively accessible, there are still issues of unbalanced supply and demand. This paper proposes targeted suggestions for the optimization of elderly care facility layout and points out the room for improvement in research methods and future research directions.

Key words: community elderly care services, 15-minute community life circle, spatial layout optimization, Caoyangxincun neighborhood
