【摘要】：收入分配决定了一个国家能否保持和谐稳定、长治久安。我国处于经济转型的重要时期，出现了收入分配不公、贫富差距拉大等一系列问题。这些问题极易引发社会矛盾，并由此关系到经济的持续发展和社会的长久稳定。近年来，国家政府相继出台了一系列政策用于调整收入分配格局，学术界对于收入分配问题的探讨也从未间断，越来越多的学者直接着眼于收入的分布形态、关注各收入群体规模的测度及变动、更为形象直观地考察收入分配格局的演变。本文即综合借鉴国内外现有研究成果，设计了一种反映收入群体异质性的半参数混合分布测度方法来刻画我国收入分布变动趋势，在此基础上提出使用-分位点来对低、中、高收入群体进行界定，，测算各群体规模变动并基于Shapley分解原则对变动进行因素解构，了解群体规模变动过程中各群体间的相互作用。通过使用1993~2011年CHNS住户调查数据进行实证研究，结果表明，混合分布模型能够有效描述居民收入分布的多峰特征且具有较好的拟合效果；城乡收入群体规模变动效应大体一致，低收入群体内部收入的增长可促进自身规模的缩小及其他群体规模的扩大，中收入群体内部收入的增长同样有助于低收入群体规模的缩小，同时还可促进中低收入群体规模的缩小和自身规模的扩大，高收入群体内部收入水平的上升则更多地导致其自身规模的扩大，此外，各群体内收入分配差距的扩大多会阻碍“橄榄型”格局的形成；城乡收入群体规模变动效应的差异则仅体现在少数个别作用的方向或效果的相对强弱上。
[Abstract]:Income distribution determines whether a country can maintain harmony, stability and long-term stability. China is in an important period of economic transformation, and a series of problems, such as unfair income distribution and widening gap between the rich and the poor, have emerged. These problems can easily lead to social contradictions. And this relates to the sustained development of the economy and social stability for a long time. In recent years, the national government has issued a series of policies to adjust the pattern of income distribution. Pay attention to the measurement and change of the scale of each income group, investigate the evolution of income distribution pattern more vividly and intuitively. This paper designs a semi-parametric mixed distribution measure method reflecting the heterogeneity of income groups to describe the changing trend of income distribution in China. Based on the principle of Shapley decomposition, the factors of the changes are analyzed, and the interaction between the groups in the process of group size change is understood. By using the CHNS household survey data from 1993 to 2011, the results show that the mixed distribution model can effectively describe the multi-peak characteristics of the income distribution of residents and has a good fitting effect, and the effect of the scale change of urban and rural income groups is basically the same. The growth of the internal income of the low-income groups can promote the reduction of their own size and the expansion of the size of other groups, and the growth of the internal income of the middle income groups can also contribute to the reduction of the size of the low-income groups. At the same time, it can also promote the scale reduction and expansion of the middle and low income groups, and the increase of the income level within the high income groups will lead to the expansion of their own scale, in addition, The widening of the income distribution gap in each group will hinder the formation of the "olive-shaped" pattern, while the difference in the effect of the scale change of urban and rural income groups is only reflected in the direction of a few individual roles or the relative strength of the effect.
