数字经济对城乡融合高质量发展的影响——基于长三角地区的实证
The Impact of Digital Economy on the High-Quality Development of Urban-Rural Integration—Based on the Empirical Evidence of Yangtze River Delta

本文以长三角地区2011~2021年41个城市数据作为研究样本，使用熵值法测度数字经济发展和城乡融合高质量发展指数，通过时间和城市双重固定效应模型实证检验长三角地区数字经济对城乡融合高质量发展的促进作用以及中介效应。研究结果发现：长三角地区数字经济能显著推动城乡融合高质量发展，乡村产业振兴起到中介作用。基于区域异质性分析发现，数字经济对中心城市和非中心城市城乡融合高质量发展水平的提升均为促进作用，且对中心城市的作用效果更明显。
This paper selects the data of 41 cities in the Yangtze River Delta region from 2011 to 2021 as research samples, and uses the entropy method to measure the digital economy development and the high-quality development index of urban-rural integration, and empirically tests the promoting role and intermediary effect of the digital economy on the high-quality development of urban-rural integration in the Yangtze River Delta region through the double fixed-effects model of time and city. The results show that the digital economy in the Yangtze River Delta can significantly promote the high-quality development of urban-rural integration, and the revitalization of rural industries plays an intermediary role. Regional heterogeneity analysis reveals that the digital economy promotes the improvement of the high-quality development level of urban-rural integration in both central cities and non-central cities, and the effect of digital economy on central cities is more obvious.
