中国农村居民收入流动性研究——基于绝对收入流动性的视角

Income Mobility in Rural China:Perspective from the Absolute Income Mobility

利用CHNS的六轮农村居民收入调查数据,从绝对收入流动的视角对中国农村居民的收入流动性及其来源进行了分析。研究发现:(1)中国农村居民的绝对收入流动性处于比较高的水平,并且长期内的收入流动性程度要高于短期。(2)以1996年和2003年为拐点,中国农村居民的绝对收入流动性呈现出先下降后上升再下降的三阶段趋势特征。同时,中国农村居民的绝对收入流动性与同期相对收入流动性的变动趋势相同。(3)中国农村居民的绝对收入流动性主要来源于农村内部各家庭间收入地位的变动,收入增长的贡献程度次之,而农村内部收入差距的扩大对绝对收入流动性的影响有限。

Based on the six sets of panel data of rural household incomes extracted from the CHNS, this paper analyzes income mobility and its decomposition in rural China from the perspective of absolute income mobility. The major findings are ： （ 1 ） The absolute income mobility in rural China remained at a high level from 1988 to 2005, and the absolute income mobility in long-term was higher. （2） Absolute income mobility presented a tendency of decreasing first, then increasing, and decreasing again, with the two inflexion points of 1996 and 2003 ; furthermore, the absolute income mobility and relative income mobility showed the same tendency. （3） The main source of absolute income mobility in rural China was the, exchange of income positionbetween different house- holds, and the income growth played the second important role, while the enlarging income inequality only had a very limited effect on absolute income mobility.
