数字乡村建设对乡村生态振兴的影响--基于农村经济增长的中介效应分析

The impact of digital village construction on rural ecological revitalization—Based on the analysis of mediating effect of rural economic growth

基于2013—2020年中国30个省份(港澳台地区及西藏除外)的面板数据,采用基准回归、分维度回归、中介效应模型和异质性分析等研究方法,实证分析数字乡村建设、农村经济增长对乡村生态振兴的影响。研究发现:数字乡村建设显著正向影响乡村生态振兴;农村经济增长在数字乡村建设对乡村生态振兴的影响中具有中介效应;数字乡村建设均显著正向影响东部、中部、西部、东北地区的乡村生态振兴,但东部地区数字乡村建设对乡村生态振兴的促进作用明显高于中部、西部、东北地区。据此,提出健全农村数字基础设施、推进数字技术与农业融合发展、实施差异化的数字乡村发展策略等措施,以强化数字乡村建设对乡村生态振兴的积极作用。

Based on the panel data of 30 Chinese provinces(excluding Hong Kong,Macao and Taiwan and Tibet)from 2013 to 2020,the research methods of benchmark regression analysis,sub-dimensional regression,mediating effect model and heterogeneity analysis were used to empirically analyze the effects of digital village construction and rural economic growth on rural ecological revitalization.The study found that digital village construction significantly and positively influenced rural ecological revitalization.Rural economic growth had a mediating effect in the influence of digital village construction on rural ecological revitalization.Digital village construction significantly and positively influenced rural ecological revitalization in eastern,central,western and northeastern regions of China,but the promotion effect of digital village construction on rural ecological revitalization in eastern regions was significantly higher than that in western,central and northeastern regions.Accordingly,measures such as improving rural digital infrastructure,promoting the integration of digital technology and agriculture,and implementing differentiated digital village development strategies are proposed to strengthen the positive effect of digital village construction on rural ecological revitalization.
