摘要
以甘肃省县域人均GDP为测度指标,运用变异系数、锡尔系数和空间自相关等方法,结合Arc GIS 10.2及Geo DA软件对甘肃省2001~2013年县域经济的空间差异及演变过程进行研究。结果表明,在时间上甘肃县域经济的差异在逐年增大,2011年后呈现急剧增大的趋势;在空间上县域经济总体有显著的聚集态势,局部空间分析发现,甘肃省县域经济两极分化明显,河西地区经济发展水平较高,陇中和陇南的大部分县域经济发展水平较低;从分解分析来看,分区内部差异略大于分区之间差异,区域内部差异是构成差异的主要因素。
By selecting the per capita Gross Domestic Product of every county, this article uses the methods of exploratory coefficient of variation, theil index and spatial autocorrelation, and the software of ArcGIS10.2 and GeoDA to study the county economy of Gansu province from 2001 to 2013. The results show that： The difference of county economy is increasing year by year in terms of time, especially from 2011. And the county economy has significant gathering momentum in terms of space. Local space analysis found that the county economy obviously shows the trend of polarization, the economic level of Hexi area is higher, and Longnan area is lower. From the perspective of decomposition analysis, the economic disparities of within four big areas are slightly larger than the area between, and the disparities within areas is the main factor.
