要素密集度偏向型出口技术结构升级的收入分配效应——基于我国省级动态面板数据的GMM方法

Effect of Factor Biased Export Technology Structure Increase on Income Distribution:Evidence from Province Level Dynamic Panel Data Model with GMM Estimation

基于我国28个省级区域的出口数据,运用修正后的Hausmann(2005)模型测度了各省级区域2002-2008年劳动和资本密集度偏向型产业的出口技术结构。在此基础上,运用差分GMM估计从全国和区域双层面对要素密集度偏向型出口技术结构升级的收入分配效应进行了实证分析。结果表明:近年来,我国资本和劳动密集度偏向型产业的出口技术结构都有较大的提升,但两种密集度产品技术含量的差距在不断扩大;Stolper-Samuelson定理在我国是适用的,劳动密集度偏向型出口技术结构升级对劳动收入占比具有显著的促进作用,而资本密集度偏向型出口技术结构表现为显著的负作用;导致我国出口增长与劳动收入占比下降"相悖"现象的原因在于资本密集度偏向型产品的出口增长速度快于劳动密集度偏向型产品。

Based on 28 provinces’ export data,this paper estimates each province’s factor biased export technology structure from 2002 to 2008 by Haus-mann（2005） Model,moreover,it takes advantage of difference GMM method to estimate labor and capital biased export technology structure’s effect on the in-come distribution.The results show that： First,any factors biased export structure of China increase quickly,and the difference between capital biased and labor bi-ased enlarged;Second,the Stolper-Samuelson theory can explain the export situa-tion of China,the effect of labor biased export technology structure increase on the labor share is positive,but the capital biased effect is negative;Third,capital biased products export increasing much quicker than labor biased products leads to the deviation between export and labor share.
