SPATIO-TEMPORAL EVOLVEMENT OF REGIONAL ECONOMIC DEVELOPMENT DISPARITIES IN CHENG-YU ECONOMIC ZONE
基于1999-2008年人均GDP和GDP数据，定量分析了成渝经济区县域层面的区域差异时空动态，发现经济收敛趋势不显著，空间依赖性强，核心区极化作用主导且加深。
Based on the data of per-capita GDP and GDP during 1999-2008,the spatio-temporal dynamics of regional disparities at the county level in Chengyu Economic Zone(CEZ) were discussed quantitatively by combining with the traditional statistic method and GEODA software.The results showed that it was no significance for the convergent trend of the regional economy,and the characteristics of the dualistic structure were significant especially in space dependence in the CEZ.On the whole,a space structure in the CEZ was formed that the developed regions centered on the urban districts of Chengdu and the backward areas were mainly in the Northern Szechwan and Northeastern Chongqing.Polarized function of economy in the core areas played a leading role and polarized tendency had further deepened in the economic development of the CEZ.Based on the regionalism,the interior disparity in the CEZ was the leading contributor of CEZ economy and the contributing effect lessened.As far as the economy compartmentalization was concerned,the disparities from the five secondary economy sections(Chengdu Economic Zone,Southern Szechwan,Northern Szechwan,One Hour Economic Circle round Chongqing,and Northeastern Chongqing) and the inner disparities of Chengdu Economic Zone played a role in the regional economic disparity of CEZ.
