基于ESDA的内蒙古自治区县域经济差异分析

County-Level Economic Disparities in Inner Mongolia Based on ESDA

基于ESDA全局和局部空间自相关分析,利用内蒙古自治区2001年、2003年、2005年、2007年及2009年县域人均GDP数据,对内蒙古自治区县域经济发展水平的空间差异程度进行了分析。分析结果表明:(1)2001至2009年,内蒙古自治区县域经济发展呈明显的空间集聚现象,但Moran's I值有降低的趋势,县域经济差异扩大。(2)内蒙古自治区的局部空间集聚现象亦十分显著,"高—高"关联的县域主要分布在鄂尔多斯市,"低—低"关联的县域分布在赤峰市和乌兰察布市等地区。

Based on global and local spatial autocorrelation of ESDA, the spatial differences of the regional economic develop- ment level of Inner Mongolia was investigated by using the data of GDP per capita at county level in 2001,2003,2005,2007 and 2009. The results indicated that the spatial agglomerate phenomenon of regional economic development levels of Inner Mongolia appeared on the whole since 2001. However, from 2001 to 2009, the Moran＇s I value had a descendant trend, suggesting the enlargement of the prefectural economic difference. Significant local spatial auto-correlation was also found. The counties with the significant ＂high-high＂ correlation were mainly distributed in Erdos. While the counties with the significant ＂low-low＂ correla- tion were located in Chifeng and Ulanqab.
