黄河流域数字经济对乡村振兴影响的空间效应与机制

Spatial Effects and Mechanisms of Impact of Digital Economy on Rural Revitalisation in the Yellow River Basin

基于2011—2020年黄河流域九省(区)面板数据,运用核密度估计等方法对流域内数字经济与乡村振兴的时空演化特征进行探究,利用动态空间杜宾模型与中介效应模型分析黄河流域数字经济对乡村振兴的影响。结果表明:(1)黄河流域数字经济与乡村振兴总体呈现上升趋势,存在较强空间异质性。(2)黄河流域内数字经济对乡村振兴呈现出显著促进作用,通过内生性检验、政策效应检验,结果仍然稳健。数字信息基础、数字金融平台对流域内乡村振兴具有显著促进作用,且存在空间溢出效应,而数字农业产业化仅对流域内乡村振兴产生促进作用,对邻接地区空间溢出效应并不明显。(3)黄河流域数字经济可通过技术进步与消费升级两方面助力乡村振兴。

Based on the panel data of nine provinces in the Yellow River Basin from 2011 to 2020,this study explores the spatio-temporal evolution characteristics of digital economy and rural revitalisation in the basin using Kernel density estimation and other methods,and analyses the impact of digital economy on rural revitalisation in the Yellow River Basin by using the dynamic spatial Durbin model and mediation effect model.The results show that:(1)The digital economy and rural revitalisation in the Yellow River Basin show an overall upward trend with strong spatial heterogeneity.(2)The digital economy within the Yellow River Basin presents a significant promotion effect on rural revitalisation,and the results remain robust through endogeneity test and policy effect test.The digital information base and digital financial platform have a significant promotion effect on rural revitalisation in this region,and there is a spatial spillover effect,while digital agricultural industrialisation only has a promotion effect on rural revitalisation in this region,and the spatial spillover effect on the neighbouring regions is not obvious.(3)The digital economy of the Yellow River Basin can help rural revitalisation through technological progress and consumption upgrading.
