Abstract：Drawing on the coupling theory，this study takes the senior care facilities in China from 2017 to
2023 as the research object. The entropy method and the coupling coordination degree model are used to
analyze the spatial ⁃ temporal evolution characteristics of the supply and demand for senior care facilities in
China. The results show that both the comprehensive evaluation index of supply and demand of senior care
facilities in all provinces have been steadily increasing，yet with an obvious trend of regional differentiation.
The coupling degree between supply and demand of senior care facilities in most provinces has reached a high
level coupling，indicating a strong correlation between the supply and demand systems. However，the coupling
coordination degree between supply and demand still remains at a relatively low coupling coordination level. The
spatial⁃temporal evolution of the coupling coordination degree of senior care facilities is evident，showing an
overall decreasing spatial distribution pattern from the eastern region to the inland area. Based on this，

governments should allocate and plan senior care facilities reasonably. All regions should formulate development
strategies for senior care facilities tailored to local socio ⁃ economic characteristics and the demographic
characteristics of older adults，so as to promote the coordinated coupling development of supply and demand for
senior care facilities.
Key words：senior care service facilities；supply；demand；coupling coordination degree
