基于多重计量偏误的农村代际收入流动分位回归研究

Study of Quantile Regression of Intergenerational Income Mobilityin Rural China based on Multiple Biases

文章利用中国健康与营养调查数据中的农村家庭数据,在综合考虑暂时性收入偏误、生命周期偏误、同住选择和工作选择偏误后运用分位回归对中国农村家庭的代际收入弹性进行估计。实证结果表明,在收入分布的两端,由于个体特征的差异导致农村家庭呈现出较强的代际收入流动性;而在中位数附近则呈现出较低的代际收入流动性。

Based on the Rural China's data collected from China Health and Nutrition Survey,with the considerations of multiple measurement biases such as the effect of transitory earnings,life-cycle bias,job choices and coresidence,this paper provides estimates of permanent income mobility across generations by using quantile regression.The result indicates that the intergenerational income mobility at the top and the bottom of income distribution is higher than that at the median income distribution because of the individual difference.Regional Mismatch Between Labor Force Resources and Economic DevelopmentLiang Yongmei and Others ·36·By using the slacks-based measure of inefficiency,we calculate the average labor quality in provinces and then the labor efficiency by labor's quality.We find that labor quality in the Middle and the West of China is higher than that in Eastern China.However skilled labors in the Middle and the West are not employed efficiently due to the slow regional economic development and lagging behind in industrial structure upgrading;reversely,the labor efficiency in East China is higher.So,labor mobility in the whole country should be enhanced to increase the labor efficiency.
