行业利润率平均化判别:垄断性行业与竞争性行业

Discrimination on Industry Average Profit Margin: Monopoly Industries and Competitive Industries

通过对6个典型垄断行业和6个典型竞争性行业1999～2013年的利润率进行对比，以此分析马克思的利润率平均化规律是否适用于中国的行业状况，结果发现：竞争性行业的利润率基本上趋于平均化，而垄断行业的利润率由于资本和劳动力进入壁垒并没有趋于平均化：垄断行业员工工资要高于竞争性行业员工工资，且呈现逐年扩大的趋势，说明劳动力分割市场现象较为严重。

This paper analyses whether the Marx＇s theory of average profit rate of industry is applied to China, by comparing the profit rate of 12 monopoly and non-monopoly industries from 1999 to 2013. The results show that the profit rate of non-monopoly industries basically tend to average; the profit rate of monopoly industries don＇t become average due to barriers to capital and labor entry; the employees＇ income of monopoly industry is higher than the employee＇s income of non-monopoly industry and the income gap between monopoly and non-monopoly industry is widen year by year, which indicates the segmentation of China＇ s labor market is serious.
