With the accelerated arrival of an aging society, the role of Internet technology in promoting community elderly care services has become increasingly prominent. The coupling coordination model was used to analyze the relationship between Internet development and community elderly care services in 31 provinces（due to the lack of data, the statistical data mentioned here do not include the Hong Kong Special Administrative Region, the Macao Special Administrative Region and Taiwan Province）, and calculate the gray correlation degree to explore its driving factors. The empirical results show that there are significant regional differences and incomplete synchronization between Internet development and community elderly care service capabilities. The regional development of coupling coordination presents a pattern of “highest in the eastern region, followed by the central region, relatively low in the northeast region, and lowest in the western region”. Infrastructure and talent resources are the core elements driving the degree of coupling and coordination. Finally, suggestions are put forward to optimize resource allocation, strengthen infrastructure and talent team construction.
