本文转变以往关于当前收入的研究视角,以生命周期理论为基础,考虑未来收入的贴现,从而采用永久收入来分析我国各地区间收入的收敛性问题。结果表明2000-2010年间我国各地区永久收入的不均衡性要高于当前收入的不均衡性,永久收入既不存鲍对收敛,也不存在条件收敛;影响永久收入收敛性的主要因素是初始收入水平和收入增长率,而生存率对永久收入的收敛性和收敛速度影响很小。
This paper changes the previous research perspective on current income, considers the discount of future income on the basis of life cycle theory, and uses the permanent income to analyze the convergence of income among different regions in China. The results show that the imbalance of permanent income in all regions of our country is higher than that of the current income in 2000-2010. The permanent income does not converge on the two sides, and the conditions do not converge. The main factor affecting the convergence of permanent income is the initial Income level and income growth rate, while the survival rate has little effect on the convergence and convergence rate of permanent income.
