Intergenerational Income Mobility Trends in China:2000~2009
利用CHNS数据估算2000、2004、2006和2009年中国代际收入弹性，发现弹性显著下降但仍偏高，家庭因素对年轻一代收入影响较强，需进一步改革促进机会平等。
This paper uses CHNS data from 1989 to 2009,estimating China's intergenerational income elasticity of year 2000,2004,2006 and 2009.Through the optimization of estimation methods and detailed data processing, we eliminate the deviation factors and make the estimates of every year comparable,and get intergenerational income elasticity for the year 2000,2004,2006 and 2009 are 0.66,0.49,0.35 and 0.46 respectively. This reflects China's intergenerational income elasticity is substantially declined.Compared with other countries', China's intergenerational income elasticity is still on the high side.China's family factors on the influence of the younger generation income remains strong.To change this situation,China needs further reform to promote equal opportunity.
