The continuous expansion of the scale of the elderly population and the continuous acceleration of elderly population ageing have had a profound impact on China's economy, society and family, especially for the development of China's pension indusby, in this paper, taking Ganzhou City as an example, the population size, population ageing rate, urbanization rate and residential area were analyzed using Z-Scores standardized data processing model from three aspects: the population development level, the real estate market maturity degree and the service development level. The proportion of the tertiary industry and other indicators were used to explore the suitability of the development of eldedy care real estate, and cluster analysis was used to classify the sample areas according to the suitability. The results show that the 18 counties and cities in Ganzhou City could be divided into three categories, areas with poor suitability, areas with development potential, key development areas. Finally, suggestions were put forward that the target market of the development of old-age real estate could be comprehensively analyzed by combining the population development trend of the region with its thoughts and concepts, social and economic development, the maturity of the real estate market and the development of the service industry to ensure the sustainable operation of the old-age real estate. 展开更多
