贸易、生产性服务业与异质劳动工资差距

Openness、Producer Services and Heterogeneous Labor Wage Inequality

在分析贸易与收入关系的理论支柱——斯托尔帕—萨缪尔森定理有效性的基础上,本文建立了一个开放条件下的一般均衡模型来说明关税削减和生产性服务业的扩张对技术劳动与非技术劳动间收入差距的作用。同时,基于我国1990-2010年投入产出表制造行业的数据也验证了他们之间的正向关系,本文最后的结论是国际贸易和生产性服务业投入的增加都加剧了收入不平等。

The paper firstly analyze the effectiveness of Stopler-Samuelson( SS) theorem,which is the theory prop of relationship between openness and income. In the following sections,we establish a theoreticalmodel to analysis the impact of decrease of tariff,the expanding of producer services to the wage inequality between skilled labor and unskilled labor. The quantities' analysis also identified the positive relationship between them mainly using the data from input-output table of 1990-2010. Thus,we conclude trade and the expanding of producer services also increase the income inequality.
