数字经济与城乡融合发展:理论机制与实证检验

Digital economy and integrated urban-rural development:Theoretical mechanism and empirical test

构建新型城乡关系、促进城乡融合发展是推进乡村振兴的必要选择与主要路径。通过构建城乡融合发展与数字经济发展指标评价体系,基于2010-2021年省级面板数据,考察了数字经济对城乡融合发展的影响效应与作用机制。研究发现:数字经济对城乡融合发展存在显著的促进作用,该结论在经过一系列稳健性检验后依然成立;异质性分析表明,数字经济对东部地区城乡融合发展的促进作用强于西部地区,对中部地区不存在促进作用;机制分析表明,农村金融发展与财政分权在数字经济影响城乡融合发展中发挥中介效应;基于空间杜宾模型的分析表明,数字经济与城乡融合均存在空间集聚特征,数字经济对城乡融合发展具有空间溢出效应。

Building a new urban-rural relationship and promoting the integrated development of urban and rural areas are the necessary choice and the main path to promote rural revitalization.By constructing an index system for evaluating integrated urban-rural development and digital economy development,based on provincial panel data from 2010 to 2021,this paper investigates the impact and mechanism of digital economy on integrated urban-rural development.It is found that digital economy plays a significant role in promoting integrated urban-rural development,and the conclusion is still valid after a series of robustness tests.Heterogeneity analysis shows that the promotion effect of digital economy on integrated urban-rural development in the eastern region is stronger than that in the western region,but has no promotion effect in the central region.Mechanism analysis shows that rural financial development and fiscal decentralization play an intermediary role in the digital economy affecting integrated urban-rural development.The analysis based on spatial Durbin model shows that digital economy and urban-rural integration both has spatial agglomeration characteristics,and digital economy has spatial spillover effect on integrated urban-rural development.
