【摘要】:選擇崔-王指數(shù)、變異系數(shù)評估經(jīng)濟極化程度,并結(jié)合GIS空間分異和空間自相關(guān)分析,對天山南坡經(jīng)濟帶經(jīng)濟極化時空演變進行了分析。結(jié)果表明:(1)天山南坡經(jīng)濟帶的經(jīng)濟極化呈現(xiàn)不斷增強的趨勢。(2)1990年以來,極化現(xiàn)象明顯,但是經(jīng)濟總量的極化現(xiàn)象大于人均經(jīng)濟總量。(3)人均GDP和GDP的Moran's I具有相反的變化趨勢,人均GDP總體上呈增大趨勢,經(jīng)濟空間集聚程度亦呈增大態(tài)勢,GDP趨于隨機分布。(4)通過局域空間自相關(guān)分析得知,GDP和人均GDP"低低"集聚的地區(qū)主要集中在阿克蘇地區(qū),經(jīng)濟發(fā)展的熱點區(qū)主要集中在以庫爾勒市為中心的輪臺縣、焉耆縣和和靜縣且這種格局2000年以來基本上保持不變。
[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引言經(jīng)濟極化是經(jīng)濟活動在地理空間上的非均衡發(fā)展和區(qū)域差異擴大化的過程。它一方面促使區(qū)域經(jīng)濟向高端或低端發(fā)展;另一方面也促使區(qū)域經(jīng)濟同時向高端和低端2個方向發(fā)展,從而導(dǎo)致中等水平群體數(shù)量的減少,呈現(xiàn)兩極分化的趨勢。經(jīng)濟的空間極化現(xiàn)象已引起國內(nèi)外學(xué)者的關(guān)注。20
