摘要
本文运用2002年、2013年和2018年中国家庭收入调查数据,在考虑收入测量偏误和同住样本选择偏差的基础上,测算了中国1970—1995年出生群体的代际收入流动性趋势。研究发现:(1)中国居民代际收入流动性呈下降趋势,代际收入秩回归系数从“70后”的0.397上升至“80后”的0.435,进而上升至“90后”的0.493。(2)代际收入流动性趋势具有性别和户口差异。其中,男性和农业户口的代际收入流动性呈下降趋势,而女性没有显著变化,非农业户口则在“70后”至“80后”有显著下降。(3)不同类型收入的代际流动性趋势略有不同,“90后”工资性收入和主要工作收入的代际流动性与“80后”没有显著差异,但劳动收入和可支配收入均呈下降趋势。(4)同住样本选择偏差对分性别和工资性收入、主要工作收入代际流动性的敏感度较大,但也没有改变中国居民代际收入流动性总体呈下降趋势的结论。本文为提高中国居民代际收入流动性和制定促进共同富裕的公共政策提供了有益启示。
Using the data from China Household Income Project in 2002,2013 and 2018,this paper investigates the trends in intergenerational income mobility for cohorts born between 1970 and 1995,after correcting the measurement errors of income and the coresidence bias of samples.The results show that:(1)The intergenerational income mobility shows a downward trend,and the intergenerational income rank regression coefficient rises from 0.397 for the 1970-1979 birth cohort to 0.435 for the 1980-1989 birth cohort,and then to 0.493 for the 1990-1995 birth cohort.(2)The trends of intergenerational income mobility differ by gender and Hukou.The intergenerational income mobility of men and those with agricultural Hukou shows a downward trend,while there is no significant change for women in terms of the intergenerational income mobility.For those with non-agricultural Hukou,the intergenerational income mobility decreases significantly from the birth cohort of 1970-1979 to 1980-1989.(3)The trends of intergenerational mobility of different types of income are slightly different.The intergenerational mobility of wage and main work income of the 1990-1995 birth cohort is not significantly different from that of the 1980-1989 birth cohort,but the intergenerational mobility of both labor income and disposable income show a downward trend.(4)The coresidence bias of samples is more sensitive to the intergenerational mobility of subsamples by gender,wage and main work income,but it does not change the overall trends of declining intergenerational income mobility.This study provides useful enlightenment for public policy-making to increase intergenerational income mobility and achieve common prosperity in China.
