The demonstration of the establishment of age-friendly communities in China has been fully completed, and the demonstration promotion work is under way. At this point, it is very necessary and meaningful to sum up and find out the difficulties and deficiencies in the work, and give scientific feedback to the policy from practical experience. Taking community construction in Jiangxi Province as an example, this study conducted coding analysis and cluster analysis with reference to the “Detailed Grading Rules for National Demonstrative Age-friendly Communities (for Trial Implementation)”, and found the difficulties and deficiencies in improving travel facilities, providing services for older people, and improving management and security capabilities of urban and rural communities in China. The huge gap between urban and rural communities in the construction of infrastructure and construction status is clarified, and it is suggested to optimize policies from the construction of public infrastructure, the attention of special older groups, and the strengthening of talent-capital-technology security.
