中国的贸易开放与工资收入差距:来自制造业细分行业的经验研究

运用中国制造业细分行业1993—2009年间的面板数据,研究了贸易开放对行业间工资收入差距的影响。研究结果显示,随着中国贸易开放的不断深入,行业间工资收入不平等呈现出逐步扩大的趋势,这与传统贸易理论对发展中国家相对工资差距的预测是不一致的。从要素密集度的层面来看,对于资本密集型行业来说,相对于其他行业,进出口总额扩大了行业间的收入不平等,而出口变量的影响不明显;对于技术密集型行业来说,相对于其他行业,进口与出口都扩大了行业间的收入不平等。

Trade Openness and Wage Dispersion in China:An Empirical Research on Manufacturing Industry

With the panel data from 1993 to 2009 in China's manufacturing industry,this paper studies the impact of trade openness upon inter-industry wage dispersion.The result shows a positive correlation between trade openness and wage dispersion.With the deepening in China's trade openness,the inter-industry wage dispersion has been enlarged which is inconsistent with the traditional trade theory on the prediction of wage dispersion in developing countries.From the endowment-intensive perspective,for capital-intensive industry,compared with other industries,total volume of import and export expands the inter-industry income inequality but the export variable has no obvious influence.For technology-intensive industry,relatively speaking,both import and export expand the inter-industry income inequality.
