摘　　要：根据多代际收入流动的理论研究框架,基于CHIP2013和CHIP1995的调查数据,分别使用两样本两阶段最小二乘估计(TS2SLS)和分位数回归方法,估计城乡子代对父代和祖父代的多代际收入弹性,结果发现:城镇父子代际收入弹性大于农村父子,城镇居民的代际收入流动性低于农村居民;在多代际收入流动的理论模型中控制父代收入变量,城乡祖父代对子代收入的回归系数都明显下降;城乡居民的父子代际收入弹性从低收入家庭到高收入家庭都呈现递减的特征;城镇和农村居民不同收入阶层多代际收入流动现象差异明显。According to the theoretical model of multigenerational income mobility,using method of two samples two-stage least squares estimation(TS2SLS)and quantile regression methods,the multigenerational income elasticity of offspring to father and grandfather is measured based on the theoretical framework of multigenerational income mobility.The results show that the inter-generational income elasticity of urban father and son is greater than that of rural,and the influence of urban grandfather's income on the income of children is much higher than that of rural residents.In the theoretical model of multigenerational income mobility,the income variable of the father generation is controlled,and the regression coefficient of the grandfather generation to the children's income in both urban and rural areas obviously reduced.Both in urban and rural areas,the income elasticity between father and son decrease from low-income families to high-income families.Multigenerational income mobility phenomenon in different income levels of urban and rural residents differences obviously.
