Analysis and optimization of 15-minute community life circle based on supply and demand matching: A case study of Shanghai.

The 15-minute community life circle (15min-CLC) strategy is one of Shanghai's important methods for building a global city and facing a society with a more diverse population structure in the future. In the existing research, the balance between the construction of the life circle and the needs...
