浙江省劳动收入比重变动的实证研究

Empirical Researches on the Changes of Labor Income Share in Zhejiang Province

本文以浙江省为例,对劳动收入比重变动的机理进行了分析。在机理分析中,对劳动收入比重的变化率进行了分解,得出三个主要因素:系数大小、人均资本及要素偏向型技术进步。与此同时,运用"动态最小二乘法"对浙江省的劳动弹性进行测算,并对浙江省1985-2007年的劳动收入比重变化进行了实证分析。通过研究发现:人均资本增长能够提高劳动收入比重,系数则缩小了资本对劳动收入比重的正向拉动作用,造成浙江省劳动收入比重下降最主要的原因是要素偏向型技术进步,提高私营企业投资占总投资比重以及人均资本存量可以提高浙江省劳动收入比重,而工业化进程加快、FDI以及劳动偏向性技术进步等因素则降低了浙江省劳动收入比重。

Taking Zhejiang province as the example,this article analyzed the mechanism of labor income share changes,and empirically researched on the labor income share.In the mechanism analysis,the paper decomposed the change rate of labor income share,and obtained three main factors,that were coefficient,per capita capital and factor biased technical progress.Meanwhile,the labor elasticity was calculated by ' dynamic least squares ',and the labor income share changes during 19852007were empirically analyzed.The results show that the increasing of per capita capital can enhance the labor income share,but the coefficient reduces the positive effect of capital on the labor income share.The main reason which causes the decrease of labor income share is factor biased technical progress.Enhancing the proportion of private enterprises in the total investment proportion as well as the stock of per capita capital can increase the labor income share in Zhejiang,but the accelerated industrialization,FDI as well as factor biased technical progress will reduce the labor income share.
