Research on Planning and Layout of Elderly Care Service Facilities based on Supply- Demand Matching

Population aging is one of the key issues concerned by the current society. Whether the allocation of elderly care facilities is reasonable or not is very important for the improvement of urban quality and the realization of social equity. At present, there are quite a few studies on elderly care facilities, but they mostly conduct analyses from a single perspective of elderly care institutions or community elderly care facilities, and the evaluation content is also limited to the rationality of the number and spatial distribution of facilities, resulting in one-sided research results. This paper utilizes multiple data sources including the data of community level elderly permanent residents in Wuhan in 2018, the data of elderly care facilities in Wuhan in 2020, road traffic, and other big data. We first integrates community elderly care facilities into the urban elderly care service system, and then comprehensively evaluates the relationship between supply and demand of facilities from the perspectives of elderly care facilities and elderly care services. The results show that: (1) At the regional level, the elderly care facilities in Wuhan show the characteristics of "core edge" of agglomeration in the central urban area and dispersion in the periphery. There are still some problems in the supply level, such as unreasonable quantity hierarchy and large gap in regional allocation level; (2) At the community level, using the two- step mobile search method, this paper finds the matching degree of supply and demand of elderly care facilities in Wuhan: Urban Development Area > Central Urban Area > far urban area; (3) In terms of elderly care services, the supply-demand relationship between medical care and spiritual comfort services in Wuhan is poor, and the facilities generally lack professional service supply, so it is difficult to meet the high- quality and diversified elderly care needs. In view of the existing problems of the matching degree between the supply and demand of old-age facilities and the elderly population, this paper puts forward optimization suggestions from the aspects of system construction, spatial layout, and implementation management, and uses the minimum facility point model to implement the suggestions to the spatial level in order to provide effective reference for the planning of elderly care facilities in similar areas. © 2022, Science Press.
