摘　　要：文章采用中国2004-2012年行业面板数据,基于多层次线性模型,研究了行业垄断对行业收入差距的直接影响和间接影响。研究发现:行业垄断对行业收入差距的直接影响和间接影响分别可以解释行业收入差距的6.30%和64.73%;行业垄断与人力资本和外商直接投资的交互项对行业工资的影响为负,说明中国垄断行业并不具备人力资本及效率优势,主要依靠瓜分本该归国家或全民所有的垄断利润而获取高额收入,因此,应将中国垄断行业的高收入问题归因于行政垄断。Based on the nonparametric Kernel density estimation, this paper found that Chinese industry income gap widening, high income and low income industry increasing, but did not appear polarization trend. This paper stud- ies both the direct and indirect effects of industrial monopoly on industry income gap by using the multi-level linear model. The results show that：the direct effects and indirect effects of industry monopoly on industry income gap can explain the industry income gap to the extent of 6. 30% and 64. 73% respectively. The scale of monopoly enter- prism in China is too big, so it shows extremely low efficiency in the use of human capital and foreign direct invest- ment. Relying on dividing up the monopoly profits which belongs to the country or the whole people to get the high income would only due to the judgment that administrative monopoly is the main reason of the problem of high income in Chinese monopoly industries.
