中国行业收入差距研究述评

A Review on the Study of China's Industrial Income Gap

通过对中国行业收入差距相关研究文献的考察,本文得出以下一些结论:行业大类数据要比现在普遍应用的行业门类数据更具适用性;应用较广的绝对指标缺陷明显,不宜再用;加权与不加权的差距测度结果对于行业收入差距的研究均很有意义;非参数核密度估计是研究收入分布的一个良好方法,但须注意应用不同层次的数据所带来的结果差异;不同于既有研究所用的方法,均值化方法能够对个体行业收入水平实现横向纵向的可比;通过将中国行业收入差距的既有解释性结论与系统的经济理论框架相参照,可以发现,国内文献对行业收入差距的解释存在着研究范围狭窄、观察归纳的部分解释因素不符合理论演绎结果等缺陷与误区。

Though reviewing the literature on China＇s industrial income gap, this paper has made some conclusions as： the high group data is better in applicability than the sector data that used commonly at present; it is apparent defect with absolute index, so it is better dont be adopted again; both the weighted outcome and the non -weighted outcome are significant for the study on industrial income gap; the non -parametric kernel density estimation is a favorable method for studying industrial income gap, but it is must be noted the different outcomes when used different gradation data; being differ from existing study, mean normalization method could make the income level of industry unit be comparable both in vertical direction and horizontal direction; though contrasting the existing explain with the systemic economics theory framework, it could find there are some deficiencies and mistakes with the explain on industrial income gap in domestic literature, what like research cope is confined and some factors from observation and induction are not in accord with the result from academic deduction.
