摘要 基于2002年、2007年、2010年和2012年中国30个省(自治区、直辖市)区域间投入产出表,考察了国内价值链嵌入对技能工资差距的影响及作用机制。结果表明,国内价值链嵌入对技能工资差距具有显著的负向影响,即国内价值链嵌入缩小了技能工资差距。在引入省区异地官员交流工具变量缓解内生性后,结果仍是稳健的。机制分析发现,国内价值链嵌入促使技术进步更偏向低技能劳动密集型部门,阻碍了产业结构升级,从而引致对低技能劳动相对需求增加和工资水平上升,一定程度上缩小了技能工资差距。最后,纳入全球价值链变量后发现,国内价值链嵌入削弱了全球价值链嵌入带来的技能工资差距扩大效应。研究结论对区域经济一体化背景下国内价值链的重塑以及共同富裕的实现具有重要的政策启示。 Based on the inter-regional input-output tables of 30 provinces(municipalities and autonomous regions)of China in 2002,2007,2010 and 2012,this paper studies the impact and mechanism of domestic value chain embeddedness on skilled-unskilled wage gap.The results show that the embeddedness of domestic value chain has a significant negative impact on the sklled-unskilled wage gap,that is,the embedding of domestic value chain reduces the skilled-unskilled wage gap of workers.After introducing the instrumental communication tool variables of provincial and regional officials from different places to alleviate the endogenesis,the results are still robust.The mechanisms analysis indicates that the embedding of domestic value chain drives technology progress more toward unskilled labor-intensive sectors and hinders industrial structural upgrading,which leads to an increase in relative demand for low-skilled labor and wages.To a certain extent,it narrows the skills wage gap.Finally,after including the global value chain variables,it is found that the embedding of the domestic value chain weakens the widening effect of the skilled-unskilled wage gap caused by the embedding of the global value chain.The conclusions of this study have important policy implications for the reconstruction of domestic value chain and the realization of common prosperity in the context of regional economic integration.
