甘肃省县域经济增长与空间格局演变探析

Spatial structure evolution of county-level economic growth in Gansu Province

以县域为研究单元,经济综合发展水平为测度目标,利用ESDA与传统的统计学方法相结合,对1995—2008年甘肃省县域经济的时空格局特征及空间作用类型进行了初步探析.结果表明,1995—2008年,甘肃省经济差异不断变大,陇中、河西、陇南、陇东4地区间的差异以及陇中、河西内部的差异是甘肃省整体差异的主要贡献者;高水平县集中分布于河西、陇中地区,低水平县集中分布于陇东、陇南地区;高增长型县域呈现向河西地区集聚的空间特征;根据县域与相邻县域之间的关系,甘肃省县域可分为"高原"型、"山顶"型、"盆地"型、"平原"型.

Spatial-temporal difference and economic characteristics of county level in Gansu Province during 1995—2008 have been preliminarily probed into by the traditional statistical method of combining ESDA.The study is done on the base of county level economics measured by the comprehensive indexs of economic development.The results show that：during 14 years,the economic differences of Gansu Province keep continuously variable big trend and the economic polarization are very serious.The integral economic disparities of county level in Gansu Province are bred by the disparity among Hexi,Longzhong,Longdong,Longnan and the disparity inside Longzhong and Hexi.The high level of county concentrate in the Hexi,Longzhong area of Gansu Province,the low level of county concentrate in the Longdong,Longnan area of Gansu Province,the high growth of county concentrate in the Hexi area space.Based on the statistical data,the relationship between each county by local Moran＇s I are divided into four patterns：＂plateau＂,＂peak＂,＂basin＂,＂plain＂.
