摘　　要：重塑新型城乡关系、推动城乡融合发展是实现共同富裕的必由之路。文章采用主成分分析方法对2011~2019年中国285个地级市的城乡融合水平进行测算与评价,并对数字经济如何影响城乡融合进行实证分析。结果表明:数字经济对城乡融合发展具有正向影响,该结果在一系列稳健性检验和内生性讨论中仍然成立;数字经济在不同的空间地理位置、政策环境背景及城市规模等级下对城乡融合存在异质性影响;产业结构升级在数字经济促进城乡融合过程中发挥着部分中介效应;门槛模型显示数字经济对城乡融合发展的正向影响呈现边际效应递增的非线性特征。文章为丰富数字经济研究、促进城乡协调发展提供了重要参考。Reshaping the new urban-rural relationship and promoting urban-rural integration is the only way to achieve common prosperity.This paper uses the principal component analysis method to measure and evaluate urban-rural integration of 285 prefectural cities in China from 2011 to 2019,and conducts an empirical analysis of how the digital economy affects urban-rural integration.The results verify that the digital economy has a positive impact on urban-rural integration,which holds true in a series of robustness tests and endogenous discussions.The digital economy has a heterogeneous impact on urban-rural integration under different spatial geographic locations,policy environment backgrounds,and city scales.Industrial structural upgrading plays a partial intermediary role in the process of the digital economy promoting urban-rural integration.The threshold model demonstrates that the positive impact of the digital economy on urban-rural integration has a nonlinear characteristic of marginal increase.This paper provides important reference for enriching digital economy research and promoting the coordinated development of urban and rural areas.
