非熟练劳动力工资上涨对收入差距的影响——基于劳动力要素价格影响评价方法的研究

Impact of Rising Wages among Unskilled Labors on Wage Gaps——Evaluation Method on Labor Price Perspective

本文基于非熟练与熟练劳动力要素价格这一独特视角,采用无条件分位数回归与其分解方法,经过1991-2011年两者工资差距数据的检验。研究发现非熟练与熟练劳动力的工资差距与不同分位数上的工资增长密切相关,表现为随之扩大的态势。其中,对非熟练劳动力歧视的加剧是造成两者工资差距在不同分位数上持续扩大的最重要原因。基于此,激励更多的非熟练劳动力通过技能培训和教育积累转为熟练劳动力,同时,消除对非熟练劳动力的各种歧视是未来缩小两者工资差距的重要手段。

Based on the unique perspective on the factor prices between un- skilled and skilled labors, the paper examines the change trends of the wage gaps from 1991 to 2011, by using unconditional quanti]e regression and the correspond- ing decomposition. The empirical results indicate that the wage gaps between un- skilled and skilled labors continue to increase, closely related in the rising wages at different quantiles. The aggregated discrimination against unskilled labors is the main reason. Based on this, more unskilled labors can be motivated to become skill labors through skills training and accumulated education. Fur- thermore, eliminating all kinds of discriminations against unskilled labors will be an important means of reducing the wage gaps in the future.
