中间品贸易与制造业工资:基于全球价值链功能视角

Intermediate Trade and the Manufacturing Wage:From the Perspective of Global Value Chain Function

本文研究高、低技术中间品投入的差异性工资效应,通过拓展异质性企业外包理论并基于全球价值链功能视角构建关键指标进行实证,研究发现:(1)高技术中间品贸易能够显著提高企业工资,且对初始生产率低的企业影响更大,而低技术中间品则带来分配效应。(2)高技术中间品通过提升企业技术水平对工资产生正向作用,低技术中间品则通过影响企业加成率产生分配效应。(3)高技术中间品能够降低企业间的工资差距及低生产率企业的市场退出概率,而低技术中间品的效果则相反。本文就贸易开放过程中如何解决收入差距扩大,促进共同富裕提出了相应的政策建议。

This paper investigates the differential wage effects of high-tech and low-tech intermediate inputs.By expanding the heterogeneous firm offshoring theory and constructing key indicators from the perspective of global value chain function,we conduct empirical tests and find:(1)high-tech intermediate trade significantly raises wage of firms,and has a greater impact on firms with low initial productivity,while low-tech intermediate trade brings a distribution effect;(2)by improving the level of firms’technology,high-tech intermediate trade raises wage,while low-tech intermediate trade has a distribution effect by affecting the markup ratio of firms;(3)high-tech intermediate trade reduces the wage gap among firms and the market exit probability of firms with low productivity,while low-tech intermediate trade has opposite effects.This paper puts forward policy suggestions to narrow the income gap and promote common prosperity in the process of trade liberalization.
