摘　　要：城乡融合是破解社会主要矛盾、实现高质量发展的必由之路,蓬勃发展的数字经济为城乡融合提供了新动能。本文测度了2011—2020年中国30个省市(因数据缺失,不包括西藏和港澳台地区)的城乡融合和数字经济发展指数,在分析数字经济对城乡融合影响机理基础上运用中介效应模型和空间杜宾固定效应模型来检验数字经济对城乡融合的影响。结果表明:数字经济对城乡融合产生显著的正向影响,并通过改善资本要素错配和数据要素错配对城乡融合形成间接促进效应。最后,空间杜宾固定效应模型发现数字经济对城乡融合的积极影响存在空间溢出和区域异质性的特点。因此,应推动数字技术在农业、医疗、教育、电商等领域的应用,加强资源共享,构建数字经济普惠格局,打破城乡分割的“藩篱”,助推区域协调,最终实现城乡融合。Urban rural integration is the only way to solve the major social contradictions and achieve high-quality development.The booming digital economy has provided new impetus for urban-rural integration.From 2011 to 2020,the urban and rural integration and digital economy development index of 30 provinces and cities in China(Due to the lack of data,the statistical data mentioned here do not include Hong Kong Special Administrative Region,Macao Special Administrative Region and Taiwan Province.)were measured.On the basis of analyzing the impact mechanism of digital economy on urban-rural integration,the intermediary effect model and spatial Dubin fixed effect model were used to test the impact of digital economy on urban-rural integration.The results show that the digital economy has a significant positive impact on urban-rural integration.The digital economy forms an indirect promoting effect by improving the misallocation of capital elements and data elements.Finally,the spatial Dubin fixed effect model finds that the positive impact of digital economy on urban-rural integration is characterized by spatial spillover and regional heterogeneity.Therefore,the application of digital technology in agriculture,medical care,education,e-commerce and other fields needs to be promoted.Strengthening resource sharing,building a digital economy inclusive pattern,and breaking the“barriers”between urban and rural areas are also important paths to ultimately achieve urban-rural integration.
