数字基础设施建设促进城乡融合发展的路径研究

Research on the Path of Digital Infrastructure Construction to Promote Urban-Rural Integrated Development

作为数字经济发展的核心动能,数字基础设施凭借着其广泛性和渗透性,深刻改变了传统经济与城乡发展模式。本文选取2011~2022年我国30个省市的面板数据,在使用熵值法测度数字基础设施建设水平与城乡融合发展水平的基础上,借助双固定效应模型实证检验二者的内在联系和作用路径,结果表明:数字基础设施建设对城乡融合发展具有显著的正向促进作用,这一结论在经过稳健性检验后依旧成立;数字基础设施建设能够通过固定资产投资效率、研发投入强度和环境规制的路径正向显著促进城乡融合发展;数字基础设施建设对城乡融合发展的影响依据地理区位异质性会呈现出不同的特征。As the core driving force of the development of the digital economy, digital infrastructure has profoundly changed the traditional economy and urban-rural development model by virtue of its breadth and permeability. Based on the panel data of 30 provinces and cities in China from 2011 to 2022, this paper uses the entropy method to measure the level of digital infrastructure construction and the level of urban-rural integration development, and empirically tests the internal relationship and action path of the two with the help of the double fixed-effect model, and the results show that digital infrastructure construction has a significant positive effect on urban-rural integration development, and this conclusion is still valid after the robustness test. The impact of digital infrastructure construction can significantly promote the integrated development of urban and rural areas through the path of fixed asset investment efficiency, R&D investment intensity and environmental regulation. The impact of digital infrastructure construction on urban-rural integration development will show different characteristics according to geographical location heterogeneity.
