中国代际收入流动性趋势分析:1991-2011

Analysis of Intergenerational Income Mobility Trend in China(1991-2011)

利用中国居民健康和营养调查(CHNS)1991-2011的数据,估计并分析了中国居民代际收入流动性趋势。研究结果表明:父代教育、职业变量是有效的工具变量,中国居民代际收入弹性在1991-2011年间平均为0.57,说明代际收入流动性整体较低;中国居民代际收入弹性在1991-2004年间总体上呈现出一种向上的趋势,并且在2004年达到峰值0.7。其后代际收入弹性在2004-2009年间经历了一个迅速下降的过程,而在2009-2011年间,代际收入弹性有所反弹。
