中国各地区城乡收入收敛性实证研究

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

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。

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.
