The coordination of elderly care services is an important part of the coordinated development of Beijing-Tianjin-Hebei region. From the perspective of matching supply and demand, this paper analyzes the achievements, problems, and development paths of the coordinated development of elderly care services in the Beijing-Tianjin-Hebei region. The results of the research indicate that the coordination of elderly care services in the Beijing-Tianjin-Hebei region has been continuously strengthened, the level of coordination in medical and elderly care services has been continuously improved, the smart elderly care services have been accelerated, and the supply of elderly care services has been significantly increased. Further analysis reveals that, at present, the coordinated development of elderly care services of Beijing-Tianjin-Hebei still faces problems such as the overall weak demand of living in different places, unmet demand for heterogeneous elderly care, unbalanced allocation of medical resources, and the ability of digital collaboration and policy synergy that needs to be improved. Therefore, it is recommended to establish a regional smart elderly care information system, deepen the coordination of medical and health services, build a diversified elderly care service supply system, and improve the elderly care service coordination mechanism, in order to make the regional elderly care service supply and demand accurately linked, and accelerate the building of a Chinese path to modernization oriented elderly care service coordination demonstration area of Beijing-Tianjin-Hebei region.
