Abstract: This paper develops a general equilibrium model with a series of intermediate goods and heterogeneous labors under a monopolistic competition market. Augmented with North and South international trade of intermediate goods, it is found that the intermediate goods trade between developed and developing countries can lead to both the growth of wage and the expanding of wage inequality in developing countries. And we also measure the impact of the trade of intermidiate goods between China and the developed countries on the wage growth of high, middle and low-skilled labor as well as on the wage inequality in 30 Chinese provinces. The empirical results turn out to be consistent with the theoreical presumption. The high-skilled labor benefit most from the technology spillover, skills premium and skill-biased technological progress brought about by the fragmentation of production.

摘要： 本文构建一个在垄断竞争市场下包含中间产品和异质劳动在内的一般均衡模型,该模型拓展到开放背景下发现南北国家的中间产品贸易导致南方国家高技能劳动与中、低技能劳动工资的增长和收入差距的扩大。测度中国与发达国家中间产品的进出口对中国30个行业高、中、低技能劳动工资增长及差距的影响,发现实证结果与理论模型相吻合。由于碎片化生产带来的技术外溢、技能溢价及技能偏向型技术进步等,高技能劳动相比其他层次的劳动而言成为最大的受益者。
