中国转型期通货膨胀对城乡收入差距的影响——基于省际面板数据的分析

本文利用我国31个省市区1979～2009年的面板数据,在运用面板数据门限模型检验我国的通货膨胀率、预期到的通货膨胀率和未预期到的通货膨胀率对城乡收入差距的影响都不存在门限效应的基础上,采用面板数据可行广义最小二乘进行估计。结果发现,我国的通货膨胀率和未预期到的通货膨胀率都扩大了城乡收入差距且是稳健的,但扩大的程度因所用数据的时间长短而异;而预期到的通货膨胀率影响城乡收入差距系数的符号和大小都因数据的时间长短而变化。

Effect of Inflation on Urban-rural Income Gap during the Transitional Period in China

Based on China's 31 province-level panel data from 1978 to 2009,this paper first finds that there is not threshold effect of inflation,anticipated inflation and unanticipated inflation on the urban-rural income gap by using panel threshold model,then estimates panel data linear model by using Feasible Generalized Least Squares.The results indicate that:China's inflation and unanticipated inflation both robustly enlarge the urban-rural income gap,but the degree changes according to time span of data.However,...
