数字经济驱动乡村振兴的内在机理与实证研究——基于农村产业融合发展的中介效应

The Internal Mechanism and Empirical Study of Rural Revitalization Driven by Digital Economy-Based on the Intermediary Effect of Rural Industrial Integration Development

文章基于2015—2020年长江经济带11个省市的面板数据,采用熵值法测度乡村振兴发展指数、数字经济发展指数以及农村产业融合指数,就长江经济带数字经济发展对乡村振兴的影响效应进行分析,同时引入农村产业融合发展的中介效应,验证以“数字经济发展—农村产业融合发展—乡村振兴”为关联的传导路径。研究结果表明:第一,数字经济能够显著促进乡村产业振兴,通过处理内生性问题和替换核心解释变量等稳健性检验,结论仍然成立,而且农村产业融合在两者之间存在部分中介效应。第二,数字经济对乡村振兴的驱动作用在数字经济发展水平不同的区域之间存在显著差异,各区域数字经济驱动乡村振兴的各个维度也存在显著差异,应在采取具体措施时各有侧重。

Drawing on the panel data of 11 provinces and direct-administrated municipalities in the Yangtze River Economic Belt from 2015 to 2020,and using the entropy method to measure the Rural Revitalization Development Index,the Digital Economy Development Index and the Rural Industrial Integration Index,this paper analyzes the impact of digital economy development on rural revitalization in the Yangtze River Economic Belt.At the same time,the paper introduces the intermediary effect of rural industrial integration development,verifying the transmission path of“digital economy development—rural industrial integration development—rural revitalization”.The results show that:First,digital economy can significantly promote revitalization of rural industry,and the conclusion is still valid by dealing with endogenous problems and replacing core explanatory variables;moreover,there are some mediating effects between the two.Secondly,the driving effect of digital economy on rural revitalization is significantly different among regions with different levels of digital economy development,and the dimensions of digital economy driving rural revitalization are also significantly different among regions,each should have its own emphasis when taking concrete measures.
