Urban shrinkage is an issue that cannot be ignored in economic development. Population is the foundation of economic and social activities and an important labor force factor in economic growth. Based on the data of urban shrinkage in 2011 and 2020, using ArcGIS software to draw urban shrinkage maps, it was found that the problem of urban shrinkage in China intensified in 2020, especially in the central and western regions and the Yangtze River Economic Belt. On the basis of analyzing the mechanism of urban contraction on urban economy, 271 prefecture level cities in China from 2011 to 2020 were selected as research objects to empirically verify the impact of urban contraction on urban economy. Research has found that urban contraction significantly reduces the level of urban economic development. With the further use of the instrumental variable method to address endogeneity issues and a series of robustness tests, this conclusion still holds. Urban contraction may affect urban economic development through channels such as negative impacts on economic and industrial agglomeration. The digital economy has weakened the negative impact of urban contraction on urban economic development. The results of heterogeneity analysis indicate that urban shrinkage has a more significant negative impact on the economy of the northeast, northern coastal areas, the middle reaches of the Yellow River, the middle reaches of the Yangtze River, and the northwest region. This enriches the research scope of urban shrinkage and provides a certain theoretical and empirical basis for the suppression of urban economic development by urban shrinkage. %K 城市收缩， %K 经济高质量发展， %K 数字经济
