收入不平等的再分配效应对经济增长的影响——一个基于中国的理论和实证研究

Impact of Income Inequality Redistribution on Economic Growth——Based on Theoretical and Empirical Analysis in China

本文在考虑经济均衡和政策均衡的基础上,通过构建一个基于世代交替模型的两阶段模型,研究了收入不平等和经济增长之间以及它们和其他经济变量之间的关系。研究发现在短期:(1)随着社会平均劳动水平增长率的提高,国民收入增长率提高。(2)当再分配系数增加的时候,国民收入增长率下降,即再分配程度和经济增长率负相关。(3)收入差距越小,国民收入增长率越高。利用中国的宏观经济数据建立SVAR模型,分析长、短期经济变量间相互影响,理论模型的结论基本得到了证实。

Based on the Economic equilibrium and policy equilibrium,we make a Two-Stage Model to study the relationship between income inequality and economic growth and other economic variables. We find,in the short run,that (1) the growth rate of GDP will increase,if the growth rate of average skill level rises;(2) when the redistribution coefficient becomes bigger,the growth rate of GDP increases more quickly;(3) the smaller income gap is,the faster the growth rate of GDP increases. Then,we employ structural vector auto-regression (SVAR) model to analyze the interaction of economic variables in a long and short horizon with China macroeconomic data.
