加工贸易与行业间收入差距——基于我国30个行业面板数据的经验研究

Processing Trade and Industrial Income Disparity: A Research based on Industrial Panel Data

本文利用2005～2008年我国制造业30个细分行业数据,研究了加工贸易对行业间收入差距的影响。实证结果表明,我国行业间加工贸易活动的差异加大了行业间收入差距,相关行业在劳动生产率、垄断程度方面的差异对我国行业间收入差距也产生了显著的正向影响;而行业总资产贡献率差异对行业收入差距具有负向影响,说明在我国加工企业中,劳动力工资水平偏低与利润被资本所有者不合理占有有关,导致行业内收入差距加大。

This paper analyses the impact of processing trade on the industrial income disparity with the related data of 30 manufacturing sub-divisions from 2005 to 2008.The final result shows that the export balance of processing trade aggravates the industrial income disparity in China.In addition,the difference of industrial labor productivity and the difference of industrial monopoly have significantly positive effects on the industrial income disparity.But the balance of the rate of total assets contribution has negative influence on the industrial income disparity,this result shows that the capitalists' unreasonable possession of the profit lowers the labor's wage level,which caused the increasing income gap in the industry.
