农村数字化如何影响农民工转移就业——基于中介效应与门槛效应的检验

How Does the Digitization in the Rural Areas Affect the Rural Migrant Workers'Transfer and Employment?A Test of Intermediary Effect and Threshold Effect

农村数字化是数字乡村建设的重要组成部分,也是促进农业农村现代化的关键举措。文章基于我国省域面板数据,分析农村数字化对农民工转移就业的影响机制。研究发现:农村数字化水平整体较低,呈现出东部、中部、东北、西部递减态势。基准回归结果表明,农村数字化有助于农民工转移就业;异质性分析结果表明,农村数字化对农民工转移就业的促进作用具有空间异质性,在东中部地区、粮食主销区作用明显;中介效应检验结果表明,农村数字化能够通过技术创新和农业劳动生产率促进农民工转移就业;门槛效应检验结果表明,农村数字化对农民工转移就业具有非线性门槛特征,随着农村数字化水平提升,其促进作用边际递减;溢出效应检验结果表明,农村数字化对农民工转移就业具有空间溢出效应。

The digitization in rural areas is an important part of digital countryside construction and a key measure to promote agricultural and rural modernization.Based on provincial panel data,this paper analyzes the mechanism of rural digitization affecting migrant workers'migration and employment.The results show that the digitization level in rural areas is relatively low and decreasing gradually from the east,the central,the northeast to the west.The benchmark regression shows that rural digitization increase the transfer employment of the rural labor.The heterogeneity analysis shows that the promotion effect of rural digitization on rural labor transfer and employment has spatial heterogeneity,and the effect is significant in the eastern and central regions as well as the regions with input of main grain for foods.The mediation effect test shows that rural digitization can promote rural labor transfer and employment through the promotion of technological innovation and agricultural labor productivity.The threshold effect test shows that rural digitization has nonlinear threshold effect on the rural labor transfer and employment with a diminishing marginal effect.The spillover effect test shows that rural digitization has a spatial spillover effect on rural labor transfer and employment.
