中国各地区城乡收入收敛性实证研究

使用1991-2011年的人均收入和CPI数据,对中国东、中、西、东北部地区进行了β和σ收敛分析,实证表明:东部地区城镇、农村人均收入在1991-2011年不存在σ收敛、β收敛,即东部地区城镇、农村人均收入差距都在不断扩大;中部地区城镇、农村人均收入在1991-2011年均存在σ收敛、β收敛,且城镇人均收入每年以17.333%的速度收敛,农村人均收入每年以8.333%的速度收敛;东北地区城镇人均收入差距在不断扩大,而东北地区的农村收入每年以3.378%的速度收敛;西部地区城镇人均收入差距在缩小,每年以8.174%的速度趋于一致,而农村人均收入差距在不断扩大;中部地区人均收入在城镇、农村上收敛速度均为最大。

The Empirical Research on Urban and Rural Income Convergence in Different Regions of China

This paper adopts per capita income,CPI of provinces in Eastern,Central,West,Northeast regions of China from 1991 to 2011 to do β and σ convergence analysis.The results indicate that：from 1991 to 2011 the Eastern Region doesn＇t play a significant role on β convergence and σ convergence of urban and rural per capita income,that＇s to say,eastern urban and rural per capita income gap are constantly expanding.The Central region exists σ convergence and β convergence,and the speed of convergence is 17.333% and 8.333% for urban and rural regions respectively.The urban per capita income gap of the Northeast continues to widen,and the rural income is on the average of 3.378% per annum rate of convergence.The Western urban per capita income gap is narrowing and the convergence rate is 8.174%,but the rural per capita income gap continues to widen.The Central Region＇s per capita income is the biggest on the convergence rate both in urban areas and rural areas.
