辽宁省44个县域经济差异的时间演变研究

采用县域人均GDP作为衡量县域经济的测度指标，运用标准差、变异系数定量分析1986～2007年辽宁省县域经济差异的时间演变特征发现，辽宁省的绝对差异逐渐增大，而相对差异在2000年之后逐渐缩小。运用基尼系数和泰尔指数分析辽宁省44个县域之间的总体差异，并对泰尔指数进行分解发现：辽宁省总差异的变化并不是由某一部分差异的变化引起的，而是由三大区块间差异和区块内部差异共同作用引起的，辽中北区域和区际之间的差异变化对辽宁省县域经济总体差异的影响较大。

How the Economic Disparities between the 44 Counties and County-level Cities of Liaoning Province Have Evolved with Time Progressing

The space-time evolution characteristics of the disparities in Liaoning county economy from 1986 to 2007 are analyzed, from which the conclusion is drawn that the absolute difference of Liaoning Province has gradually increased while the relative difference gradually has decreased since the Year of 2000. the overall difference is then analyzed using Gini Coefficient and Theil Index. By decomposing the Theil index, the conclusions are drawn that the changes of the total difference of Liaoning Province are not caused by some part of the difference, but by the joint work the differences between the three great blocks and the internal differences of each block have done; and the changes of the differences between regions in the north and middle part of Liaoning Province have produced a significant influence on the total county-economy difference of Liaoning Province.
