Types, Differences, and Optimization of the Spatial Match of Supply and Demand of Elderly Canteens in Guangzhou
Abstract
The mismatch between the supply and demand of community-service-oriented home care facilities severely restricts the effective promotion of elderly care services in communities. This study sought to accurately measure the mismatch between supply and demand in terms of accessibility and feasibility. The spatial relationship between the supply and demand of Guangzhou's elderly canteens was evaluated by a new two-step floating catchment area method—exchanging results with process variables, and based on multi-source data, including Baidu Map API and residential POI. The study found that: 1) The spatial matching score between supply and demand of Guangzhou's elderly canteens is qualified (60%) under the promotion of administrative-units-overall-coverage, identified as a "631" type structure of the balanced surplus and shortage. 2) A bias exists in terms of superiority, in that the acquisition advantage for the demand side is superior to the supply condition, and also in terms of spatial distribution, with a single-core supply structure of "depression center toward high margin" and a multi-level-core demand structure of "strong in south, weak in north". 3) Since competitive extrusion acts on the urban center, both centers in central districts and sub-centers in outer districts with travel advantage are polarized into surplus and shortage, which is mainly caused by different degrees of crowdedness. The inner-city core loses its advantage of resources and location, changing into an inner-city depression, while the Huangpu core benefiting from the rapid development of urban construction and fewer people, keeps itself at a peak. Regarding sub-centers, the central streets of Panyu and Huadu face severe insufficiency, but the situation in Conghua and Zengcheng is the opposite. For the precise allocation intervention and overall coverage of community elderly care and facilities, ideas such as stock promotion, integration in pairs of spatial correlation, and stock downsizing toward the mismatch are proposed. Priority should be given to the matching integration of surplus and shortage areas with a strong spatial correlation. Further, direct, active, and passive paths were provided for the promotion of the matched items, which provide a reference for the accurate and efficient allocation to other elderly care facilities.
