我国地区差距的度量与分解——基于省级人均GDP与居民收入的实证分析

Analysis of the Regional Disparity of China Based on the Provincial Per-capital GDP and the Residents Income

文章选取1990-2009年省级人均GDP和分城乡的居民人均收入数据,利用泰尔指数分东、中、西、东北四大地区研究我国地区差距的变动轨迹,并比较人均GDP和居民收入测度地区差距的不同。研究结果表明,我国总体地区差距在20世纪90年代中期之前显著上升,1995、1996年有所下降,1997—2003年再次上升,2004年以后有所缩小;城镇地区差距在1995年之前显著扩大,之后在波动中下降;农村地区差距总体呈上升趋势,2004年以后有所下降。人均GDP地区差距显著高于分城乡人均收入的地区差距,两者变化的趋势较为一致;农村地区差距高于城镇地区。

This paper selects the provincial per capita GDP, urban and rural residents per capita income in 1990--2009, using Theil index divided by the eastern, central, west and northeast regions to study on Chi- na^s regional disparity track and comparing the difference between the per capita GDP and per capita income regional inequality. The results show that after a significant rise in the first half of the 1990s, China＇s overall regional disparity drops down in 1995 and 1996, then increases slightly for the period 1997--2003 and has narrowed since 2004. In urban areas, the regional inequality widens rapidly before 1995, and goes in the downward trend in volatility after that. However, rural regional inequality increases overall and does not go down until 2004. Regional per capita GDP regional inequality is significantly higher than that in per capita income, and their changing trends are almost consistent. The gap in rural areas is higher than that in urban areas.
