China's Shrinkage Varieties: Addressing Long-Term and Recent Population Loss in Eastern and Northeastern Regions

China is facing an increasingly serious problem of urban shrinkage, which is embodied in the long-term massive population loss in the northeast and the short-term small population loss in the East. By comparing the characteristics of cities from several dimensions and referring to some successful cases of preventing urban shrinkage, this paper explores urban shrinkage in two different regions and development models within China. Two typical shrinkage cities, Wenzhou and Jixi, are selected as samples for this study, while statistical analyses are conducted with the help of public government information data. The result of this research is that due to varying city development patterns, Wenzhou and Jixi exhibit distinct types of shrinkage. There are different solutions for different types of urban shrinkage. Both cities should actively explore new industries and upgrade existing ones to enhance livability and community vitality, meeting residents' needs for better lives and achieving a win-win outcome.
