市场化、技能偏向性技术进步与技能溢价

Marketization,Skill-Biased Technological Change and the Skill Premium

市场化在促进技术进步的同时也提高了技能溢价。本文通过建立内生技能偏向性技术进步模型,研究市场化进程中技能偏向性技术进步对技能溢价的影响。模型表明,市场化能够更多地缩短高技能偏向性技术的市场化应用时间,促进高技能偏向性技术进步,进而提升技能溢价。本文进一步利用1995-2009年行业面板数据进行检验,发现中国的技术进步表现为高技能偏向性,市场化程度的提升显著促进了高技能偏向性技术进步,而且市场化主要通过技能偏向性技术进步渠道提高技能溢价。

Marketization can not only promote technological change, but also improve the skill premi- um This paper establishes an endogenous skill-biased technological innovation model to study the impact of skill-biased technological change on the skill premium in the process of marketization. Marketization can shorten implementation time of high skill-biased technology more than that of low skill-biased technology, thus having a greater role in promoting high-skill biased technological change and increasing the relative wage of high-skilled labors. This paper also conducts an empirical analysis using industry-level panel data of China between 1995 and 2009. Empirical results confirm the above theoretical conclusions and show that marketiza- tion affects the relative wage of high-skilled labors mainly through high-skill biased technological change.
