全球价值链分工地位对城乡收入差距的影响——基于全要素生产率和市场化的中介效应分析

Influence of Global Value Chain Division on Urban-rural Income Gap:Based on the Mediating Effect of Total Factor Productivity and Marketization

深入分析全球价值链分工地位如何影响收入分配,探讨全要素生产率和市场化的中介作用,对推动经济高质量发展和实现共同富裕具有重要的现实意义。本文基于2011—2021年我国30个省份面板数据,分别测算全球价值链分工地位和城乡收入差距,实证结果显示:全球价值链分工地位提升有助于缩小城乡收入差距,相较于东部地区,中西部地区的全球价值链地位提升对缩小城乡收入差距的作用更为显著;全要素生产率和市场化在其中起到中介传导作用,进一步测算相对贡献率可知,市场化水平相对贡献率为负,而全要素生产率的相对贡献率为正。

In-depth analysis of how the division of labor in the global value chain affects income distribution,and discussion of the mediating role of total factor productivity and marketization have strong practical significance for promoting high-quality economic development and realizing common prosperity.Based on the panel data of 30 provinces in China from 2011 to 2021,this paper calculates the GVC division status and rural-urban income gap respectively.The empirical results show that the improvement of GVC division status helps to narrow the rural-urban income gap.Compared with the eastern region,the improvement of GVC status in central and western regions has a more significant effect on narrowing the rural-urban income gap.Total factor productivity and marketization play an intermediary role in this process.Further calculation of the relative contribution rate shows that the relative contribution rate of marketization level is negative,while the relative contribution rate of total factor productivity is positive.
