我国三次产业在岗职工工资收入差异程度研究——以江苏省为例的实证分析

Research on the Income Diversity of Employees in Three Industries in China

文章根据我国收入分配差异的特点,设计了一种测试收入分配差异大小的新指标———余期望系数。该系数在一定程度上要优于基尼系数与泰尔指标,在我国有较大的适应性。笔者运用该系数以江苏省为例对三次产业在岗职工收入差异状况进行了实证分析,并据此提出了一些控制江苏三次产业在岗职工收入差异扩大的建设性意见。

Based on characteristics of the employee income in China, the writer designs a new index surplusexpectation coefficient to measure the income diversity. Superior to Ginicoefficient and Theilindex to some degrees, this coefficient is more adaptable in China. Employing this coefficient to make an empirical analysis of the income diversity of employees in the three industries in Jiangsu Province, the paper puts forward some constructive suggestions to control the income diversity of employees in the three industries in Jiangsu Province.
