短短20年间,中国的行业收入分配迅速从平均主义的一个极端走到收入差距悬殊的另一个极端。通过对15类大行业、工业行业中的30个非垄断行业及6个垄断行业进行分析,找出了影响行业收入差距扩大的主要因素,并利用非垄断行业收入的回归方程,粗略量化了垄断因素对行业收入差距的影响。
In recent twenty years, great changes from "equal principle" to "unacceptable gap" of distribution of professional income have taken place in China. According to this, we choose to dissolve the professional income on the basis of fifteen "large professions", thirty competitive professions and six monopolistic professions, to search for the chief factors affecting the gap of professional income. Besides, with the help of regression equation of competitive professions, we quantify the effect caused by monopolization indirectly.
