山西省县域经济差异的时空格局演化及驱动力分析

Analysis on the Evolution of Temporal and Spatial Pattern of County Economic Difference and Driving Force in Shanxi Province

以人均GDP为测度指标,运用变异系数、泰尔指数、ESDA、Getis-Ord G i统计指数、标准差椭圆等多种方法和技术对2006年~2016年山西省县域经济差异的时空格局演化进行了分析.结果发现:①山西省县域经济绝对差异波动性增加,而相对差异则不断缩小.②通过G指数分析山西省内部空间特征时,2006年~2016年县域热点区域先增加后减少,冷点区域逐年减少.③从经济重心和标准差椭圆的变化来看,山西省县域经济重心位于平遥县和祁县相交界的区域,经济分布呈现南—北方向格局.④将驱动力分为经济区位差异、产业结构、发展政策和交通因素4个方面.

This paper analysis the evolution of spatial-temporal pattern of county economic difference in Shanxi Province from 2006 to 2016,taking the per capita GDP as a measure index,using various methods and techniques such as C v coefficient,Theil index,ESDA,Getis-Ord G i statistical index and standard deviation ellipse.The study found that:①The absolute difference of county economy in Shanxi Province is expanding in the volatility,but the relative difference is shrinking.②From 2006 to 2016,the hot spot area in county area increased first and then decreased,and the cold spot area decreased year by year,when analying the internal spatial characteristics in Shanxi Province by the G index.③From the change of the economic center of gravity and the ellipse of standard deviation,the center of economic gravity of county in Shanxi Province is located at the junction of Pingyao County and Qi County,and the economic distribution presents a south-north pattern.④The driving forces are divided into four aspects:economic zone difference,industrial structure,development policies and transportation factors.
