With the development of China's urbanization process, in recent years, the development of cities has shifted from the incremental expansion mode of high-speed growth to the development strategy of stock renewal. At the same time, with the accelerated pace of aging and social problems, the urban community renewal represented by “Dual-aged communities”, i.e., old communities with seriously aging residents, has become a prominent challenge for sustainable urban development.
