摘要
本文选取我国30个省市自治区1997-2006年的数据,建立了一个动态面板模型,采用广义矩估计(GMM)方法对我国FDI产生的地区间及地区内的收入分配效应进行了实证检验。结果表明,外商直接投资确实拉大了我国各省自治区内部的城乡收入差距,但是却可以缩小地区间的工资差距。各地的要素禀赋差异也对地区差距起到了不同的作用,其中,低技能劳动力倾向于扩大地区间和地区内的收入差距,中等技能劳动力则能够同时缓解地区间和地区内的收入差距,高技能劳动力对地区内部收入差距的作用具有不确定性,但却能缩小地区间的差异。并且,中等技能劳动力对地区间和地区内差距的缩减弹性都是最大的。人均可耕地面积与资本产生的地区内收入分配作用正好相反,前者会扩大收入差距,而后者则能缓解收入差距。此外,对东中西三大区域的比较显示,目前中部地区省份吸引外资能够在最大程度上缩小省际间的收入差距。
This paper establishes a dynamic panel data model and uses GMM estimation method to estimate the effect of FDI on inter-regional and intra-regional income inequality based on the data of 30 provinces in China from 1997 to 2006. The results show that FDI may increase the urban-rural inequality inside provinces but decrease the wage gap between provinces. Differences of factor endowments between provinces may have different influences on regional inequality. Unskilled labor tends to increase both inter-regional and intra-regional inequality, while mid-skilled labor tends to bring opposite effects and its elasticity is the highest for the decrease of inequality. Besides, skilled labor＇ s effect on intra-regional inequality is uncertain, but it can decrease inter-regional gap. Arable land and capital may have the opposite effect on intra-regional inequality. The former could increase while the latter could decrease the inequality. Moreover, through comparison of the income distribution impact of FDI between eastern, central and western China, the paper finds that FDI in central China may contribute most to decrease its differences with the highest wage province.
