【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。
[Abstract]:Taking the per capita GDP of Gansu county as the measure index, using the methods of variation coefficient, Sier coefficient and spatial autocorrelation, combining with Arc GIS 10.2 and Geo DA software, this paper studies the spatial difference and evolution process of county economy in Gansu province from 2001 to 2013. The results show that the difference of county economy in Gansu is increasing year by year, and the trend is increasing sharply after 2011. On the whole, the county economy has a significant aggregation situation in space. Local spatial analysis shows that the county economy in Gansu Province is polarized obviously, the level of economic development in Hexi region is relatively high, and the level of economic development in most counties in Longzhong and Longnan is relatively low. From the analysis of decomposition, the difference within the region is a little larger than the difference between the regions, and the difference within the region is the main factor of the difference.
