在评析区域经济差异研究进展的基础上,以中国大陆31个省、自治区、直辖市为研究单元,以人均国内生产总值(GDP)为测度变量,定量评价了改革开放以来中国区域经济差异及空间格局变化的总体水平与特征;并引用国外最近使用的区域分离系数等方法,分析了中国区域经济增长与差异格局变化的相互关系,得出的基本结论为:随着中国经济的不断增长,其东、中、西三大区域逐渐发散趋异。而南、北两大区域逐渐收敛趋同。
On the basis of analysis of domestic and international studies on regional economic growth and spatial structure of economic inequality, using a consistent data of GDP per capita and by taking 31 provinces, autonomous regions and municipalities in mainland China as geographical research units, this paper makes a quantitative analysis of measuring the characteristics of regional economic inequality in China since the economic reforms and opening up of 1978. The result shows that the regional economic inequality has been enlarging with the regional economic increase. Using a regional separation index recently developed measures based on inequality decompositions, the paper makes a quantitative analysis of the relationship between regional economic increase and its inequality evolution in China. The general conclusion is that the continuous growth of diverges among eastern, central and western China and the continuous growth of converges between northern and southern regions, which is in some responses to national increase in China.
