摘　　要：针对当前关于收入不平等程度估计的争议,本文设计了隐性收入估计方法和收入分布函数优劣判别方法。实证分析表明,中国城乡家庭隐性收入规模一般在20%左右,城镇高收入户隐性收入最高,隐性收入规模达到了70%以上。中国城镇居民家庭的收入差距大于农村居民家庭的收入差距,两者均呈现逐年扩大的趋势,目前全国居民家庭基尼系数超过了0.5。要正确认识中国居民收入不平等程度,关注高收入者的收入膨胀,利用有效方法揭示高收入者的灰色收入规模,坚决打击非法所得,抑制城乡收入差距过快扩大的趋势。In view of the current dispute over the degree of income inequality,this paper designs an implicit income estimation method and an income distribution function discriminated method.The empirical analysis shows the scale of Chinese household's implicit income is about 20%.Urban households with high income have the highest implicit income,of which scale has been more than70%.The income gap of Chinese urban residents is larger than that of rural residents,and both of them trend to enlarge.At present,national household Gini coefficient has been more than 0.5.This paper believes that it is important to accurately understand the severity of Chinese residents' income inequality,pay attention to income expansion of high-income people,use scientific methods to reveal the gray income scale of high-income people,resolutely crack down on illegal income,and stabilize high-income people' earning.
