美国1970年-2012年劳动收入占比变动的整体性分析

劳动生产率和劳动者工资被看作是导致1970年以后美国劳动收入在增加值中占比下降的主要因素。但现有研究缺乏对此的进一步分析。以马克思对资本积累过程中可变资本在预付总资本中所占比重变化的相关分析为基础的理论拓展,有利于建立起一个统一的分析框架以说明劳动收入占比的变化。本文实证研究的结论基本支持理论分析的逻辑,剩余价值率和资本有机构成是劳动收入占比变化的最主要解释变量。

More and more investigations have shown the decline of the U. S. labor＇s share from 1970 s. It was also found that the effects of labor productivity and wage were most important. However,the existing research lacks further analysis. On the basis of Marx＇s theory about the change in variable capital share in prepaid capital in the process of capital accumulation,a unified framework for describing changes in wage share could be established. The basic conclusions of empirical research support the theoretical analysis is that the organic composition of capital and the rate of surplus value are the dominant.
