基于ESDA的浙江省区域经济差异时空演变及成因研究

Spatio-Temporal Analysis of Regional Economic Disparities in Zhejiang Province Based on ESDA

文章为探究浙江省区域经济差异的时空演化特征,以浙江省县域人均GDP为研究指标,运用基尼系数和ESDA空间统计模型,结合Arc GIS相关空间分析功能,对浙江省县域经济总体差异变化趋势和局部空间均衡程度进行定量研究。结果表明:2000年以来,浙江省经济发展水平较高的区域主要集中在环杭州湾地区,经济发展水平较低的区域主要分布在浙西南地区,总体空间差异呈逐渐缩小趋势;县域经济的局部空间差异则有所变大,主要表现为高经济水平集聚区的县域有所减少,而低水平集聚区的县域有所增多。基于以上特征,文章认为自然地理和区位条件、规划引导以及私营经济的发展是影响浙江省区域经济发展差异的重要原因。

Taking the counties of Zhejiang Province as the study object and the 2000-2013 GDP per capita as the measuring indicator,this paper analyzes the regional economic disparities from 2000 to 2013. The features of spatial-temporal pattern are discussed by Gini index and Exploratory Spatial Data Analysis（ ESDA）,and combine with the GIS spatial analyze function. The results showed that since 2000,the overall county＇s economy in Zhejiang Province have diminishing trend,higher level of economic development area mainly concentrated in the region around Hangzhou Bay,and the lower level of economic development area are mainly distributed in southwest part of Zhejiang,and the imbalance of the economic narrowed; County＇s economy of local spatial difference is becoming bigger,since counties in higher level economic agglomeration have decreased,but lower concentration increased.Based on these features,this study points out that natural geography and location conditions,planning guidance,and the development of the private economy are the main reasons for the differences in regional economic development in Zhejiang province.
