【摘要】：选择崔-王指数、变异系数评估经济极化程度,并结合GIS空间分异和空间自相关分析,对天山南坡经济带经济极化时空演变进行了分析。结果表明:(1)天山南坡经济带的经济极化呈现不断增强的趋势。(2)1990年以来,极化现象明显,但是经济总量的极化现象大于人均经济总量。(3)人均GDP和GDP的Moran's I具有相反的变化趋势,人均GDP总体上呈增大趋势,经济空间集聚程度亦呈增大态势,GDP趋于随机分布。(4)通过局域空间自相关分析得知,GDP和人均GDP"低低"集聚的地区主要集中在阿克苏地区,经济发展的热点区主要集中在以库尔勒市为中心的轮台县、焉耆县和和静县且这种格局2000年以来基本上保持不变。
[Abstract]:Cui-Wang index was selected to evaluate the degree of economic polarization with coefficient of variation, and spatial differentiation and spatial autocorrelation analysis were combined with GIS. The temporal and spatial evolution of economic polarization in the southern slope of Tianshan Mountain is analyzed. The results show that the economic polarization of the economic belt on the south slope of Tianshan Mountain shows an increasing trend since 1990, and the polarization phenomenon is obvious. However, the polarization of the total economic volume is larger than that of the per capita economy. (3) the per capita GDP and the Moran's I of GDP have the opposite change trend, and the average per capita GDP is increasing as a whole. The degree of economic spatial agglomeration is also increasing. The GDP tends to be randomly distributed. (4) based on the local spatial autocorrelation analysis, we know. GDP and per capita GDP "low" concentration areas are mainly concentrated in Aksu region, the hot spots of economic development are mainly concentrated in Luntai County with Kurla as the center. Yanqi County and Hejing County and this pattern has remained basically unchanged since 2000.

【正文快照】： 1引言经济极化是经济活动在地理空间上的非均衡发展和区域差异扩大化的过程。它一方面促使区域经济向高端或低端发展;另一方面也促使区域经济同时向高端和低端2个方向发展,从而导致中等水平群体数量的减少,呈现两极分化的趋势。经济的空间极化现象已引起国内外学者的关注。20
