摘　　要：居民收入分配是社会科学研究中长期关注的一大主题。在经济学中,收入分配持续动态表现为子代收入在多大程度上由父代收入决定,也就是代际收入弹性。运用CHNS1989—2011年九轮调查数据,进行适当的样本归并、测量误差修正和可比性调整等处理,可从纵向变动和横向异质性两个层面定量刻画中国居民收入代际弹性的变异特征,并估计分析了代际收入弹性变异对收入不平等变动的影响。研究发现:(1)中国居民代际收入弹性的纵向变动大体呈现出"M型"态势;(2)代际收入弹性在不同收入分布上存在异质性,低收入阶层的代际收入弹性显著高于高收入阶层;(3)代际收入弹性异质性对以方差表示的不平等解释力在波动中有轻微上升的趋势,2010年前后的解释程度已接近40%。Based on the collection of data from nine surveys in CHNS 1989-2011, and by merging appropriate sam- ples, correcting measurement errors and adjusting comparability, this paper quantitatively describes the variational charac- teristics of intergenerational income elasticity （liE） in China in terms of longitudinal changes and horizontal heterogeneity. The effect of liE variation on the changes in income inequality was estimated and analyzed. The results show that ： （ 1 ） IIE in China shows ＂M＂-shaped longitudinal changes; （2） liE exhibits heterogeneity in income distribution - the IIE of the low-income group is significantly higher than that of the high-income group; and （3） The income inequality, in terms of variance, can be partly explained by the liE heterogeneity, and the explanatory power shows a slight upward trend in vola- tility, reaching close to 40% around 2010. These conclusions are significant for understanding and resolving the problem of income distribution inequality in China.
