选取2011-2021年中国30个省份面板数据,构建基准回归模型和调节效应模型,实证考察数字全球价值链参与对行业收入差距的影响,并探究技术创新和产业集聚的调节效应.结果表明,数字全球价值链参与对行业收入差距呈显著倒U型影响,即随着数字全球价值链参与水平提升,行业收入差距呈现先扩大后缩小的变化趋势.调节效应检验结果表明,在东部、中部、西部与东北地区,数字全球价值链参与对行业收入差距均存在倒U型影响,但作用大小存在差异.机制分析发现,技术创新和产业集聚两个变量在数字全球价值链参与对行业收入差距的影响过程中发挥调节效应.
Impact of Digital Global Value Chain Participation on Industry Income Gap
Based on panel data from 30 provinces in China from 2011 to 2021,this paper constructs a benchmark regression model and a moderating effect model to empirically examine the impact of digital global value chain participation on the in-dustry income gap and explore the moderating effect of technological innovation and industrial agglomeration.It is shown that there is a significant inverted U-shaped relationship between participation in the digital global value chain and the industry income gap,meaning that as the level of participation in the digital global value chain increases,the industry income gap shows a trend of first expanding and then narrowing.The heterogeneity test shows that the inverted U-shaped effects exist in the eastern,central,western,and northeastern regions,but there are differences in the magnitude of such effects.Regu-latory effect test finds that technological innovation and industrial agglomeration play a moderating role in the impact of digit-al global value chain participation on the industry income gap.
