行业垄断与行业收入差距研究

Study on Industry Monopoly and Inter-industry Income Gap

利用2003～2009年相关统计资料构建面板数据,就行业垄断与行业收入差距的关系展开实证分析。研究结果表明:行业间收入差距总体呈扩大趋势,垄断行业过高的收入水平导致我国行业收入差距升水1/3左右;若考虑隐性收入,行业收入差距由32.74%上升到47.65%;假设垄断行业收入回归合理区间,行业收入差距的下降幅度约为30%;垄断行业与非垄断行业平均收入水平的差额相当于全社会各行业平均收入水平的60%～70%。因此,缩小行业收入差距,必须弱化垄断行业的管理层权力,将职工报酬的控制纳入对经营者升迁的考核,逐渐弱化垄断行业经营者激励共容的串谋空间。

This paper empirically studies the relationship between industry monopoly and inter-industry income gap according to the statistical data based on 2003-2009.The empirical research results show that： The inter-industry income gap is being increasingly expanded in general.The excessive income level of monopoly industry leads to the income gap widening about 1/3 in China.Taking into account the hidden income,inter-industry income gap has increased from 32.74% to 47.65%.When the monopoly revenues stay in a more reasonable range,the inter-industrial income gap in China will go down about 30%.The income of labors in monopoly industries is higher than in non-monopoly industries,and the higher part is about 60-70% of the average industry income in China.Therefore,it is needed to weaken the power of executive officers,to regard the operators＇ ability to control workers＇ pay as an assessment of their promotion,and to weaken the space of conspiracy among the operators of monopoly industries in monopoly industries.
