Ageing China, as one of the most significant and profound social topics, has sparked tremendous discussions in the academic field. Facing the surging and irreversible ageing trend, China is promoting community-based eldercare nationwide, which is widely named ‘the last one kilometre’. Beijing has also made its own attempts under national guidance. This dissertation is to evaluate Beijing’s practice through a mixed methodology: horizontal comparative review of Italy, the United States and Japan’s relatively mature eldercare system from a macro view and focus group interviews of two chosen communities in Beijing from a micro view to generate a comprehensive analysis. As a result, Beijing’s design can be concluded as a three-levels eldercare network with public-private partnership (PPP) cooperation as the main pattern under the leadership of the government. Regarding the elderly people’s perceptions, although price and family as the most sensitive and valued aspects of elderly people have been satisfied, and most of them expressed positive attitudes towards Beijing’s practice, some of their demands present diverse and non-uniform characteristics and are hard-to-meet through unified design. In the end, this dissertation suggests that 2 sustainable eldercare and higher prosperity for elderly people can be achieved through grass-roots empowerment and rent-seeking behavior prevention. The contribution of this dissertation is that it innovatively combines macro theoretical analysis with micro interviews, ensuring the systematic, comprehensive and practical value of the research, f illing the academic gap and providing valuable theoretical and methodological references for future research.
