摘要
缩小城乡收入差距,是实现共同富裕亟待解决的重要问题.基于偏向型技术进步理论,对数字乡村建设与城乡收入差距的关系进行理论分析,利用县域数字乡村发展指数与县域经济统计数据实证检验数字乡村建设与城乡收入差距之间的关系.基准回归结果显示,数字乡村建设对城乡收入差距的影响呈现出先缩小后扩大的U型效应,这一结果经过内生性及稳健性检验后仍然成立.从各维度看,数字基础设施对城乡收入差距的影响处于扩大阶段,而乡村经济数字化、乡村治理数字化及乡村生活数字化对城乡收入差距的影响处于缩小阶段.异质性分析表明,数字乡村建设对城乡收入差距的影响存在地区差异,对东部和中部地区影响显著,对西部地区影响不显著;在粮食主产区与非主产区均呈U型影响效应.机制研究显示,技能溢价是阻碍数字乡村建设缩小城乡收入差距的重要因素.为更好发挥数字乡村建设缩小城乡收入差距的作用,需进一步保障数字乡村发展质量,提高农村居民数字技能水平,促进资源在区域间的合理配置.
Abstract
Reducing the income disparity between urban and rural areas is a critical issues to achieve common prosperity.Based on the biased technological progress theory,this study conducts a theo-retical analysis to empirically test the relationship between digital rural construction and urban-rural in-come disparity by using the county-level digital rural development index and economic statistical data.The benchmark regression results show that the impact of digital rural construction on the urban-rural in-come disparity exhibit a U-shaped effect,initially narrowing and then widening the disparity.This result holds true after the endogeneity and robustness tests.From the various dimensions,the impact of digital infrastructure on urban-rural income disparity is in the widening phase,while the impact of rural economy digitization,rural governance digitization and rural life digitization on urban-rural income disparity is in the narrowing phase.Heterogeneity analysis reveals regional differences in the impact of digital rural con-struction on the urban-rural income disparity,with a significant effects in the eastern and central regions but no significant impact in the western regions.The U-shaped effect was observed in both main and non-main grain producing areas.Mechanism studies indicate that skill premium is an important factor hinder-ing the construction of digital countryside from narrowing the urban-rural income disparity.To better le-verage the role of digital rural construction in reducing the urban-rural income disparity,it is necessary to ensure the quality of digital rural development,enhance the digital skills of rural residents,and promote the rational allocation of resources across regions.
