摘要
以县域为研究基本单元,选取了人均GDP、人均工业总产值、农民人均纯收入和职工平均工资等四个指标,运用差异系数与极化指数等相差数理模型,对1994年以来江苏省县域经济发展差异与极化的演化过程与格局进行了定量比较,结果发现:江苏省县域经济发展差异与极化伴随着"缩小—扩大—再缩小"演化过程,总体上呈现出生产水平差异与极化增强、生活水平差异与极化减弱的特征,且生产水平的差异与极化远大于生活水平的差异与极化;在空间上,主要表现为苏南、苏中与苏北三大地区之间的差异与极化,且三大地区之间的极化呈增强趋势。
The paper makes a quantitative comparison between the differences of county economic development and the evolution process of polarization in Jiangsu province from 1994 to 2010 with the mathematical model of difference coefficient and polarization index.We use counties as basic units for study and select the value of per capita GDP,per capita gross industrial output,net income per capita and average salary from the product and life.The results are shown as below：firstly,the difference of inter-county economic development mainly manifests that the difference of production activities is greater than living standard.The former is due to the expansion of industrial production,which is increasingly concentrated.The inter-county economic development inequality has basically the same trend with its polarization and it also shows that the polarization of production activities is greater than living standard,which has the＂S＂type trend of ＂narrow-expand–narrow＂.That is to say the inter-county economic polarization strengthens with the expansion of the inter-county economic difference,which is consistent with regional economic polarization of the general laws of evolution.Secondly,the differences and polarization in space is not alike between southern Jiangsu,central Jiangsu and northern Jiangsu and the difference of production activities is also greater than living standard.In addition,the polarization among the three regions also demonstrates an increasing trend.With regard to do this,we must accelerate the development of prefectural region economy of northern Jiangsu,and then the situation of the regional economic polarization in Jiangsu province can be fundamentally weakened.The evolution state of difference and polarization in both production and life of Jiangsu province is in line with the history of world’s economic development trend.All in all,with the further deepening of our economic development,production activity will be increasingly concentrated and living standard appears the trend of convergence after differentiation,which also indicates that the unbalanced economic growth and harmonious development can go hand in hand and complement each other.
