中文摘要：

利用标准差和泰尔系数,对1995-2006年新疆区域经济发展空间总体差异水平变动及南北疆差异变动特点进行分析;应用聚类分析方法、核心-边缘理论揭示了新疆经济发展空间结构演化态势,并根据区位商理论,对空间经济结构演变的机制进行分析。研究表明：1995-2006年,新疆经济空间差异总体呈增加态势,而且南疆内部、北疆内部、南北疆之间经济差异水平均在增加,其中,南疆内部差异变动对总体差异变动的影响最大;区域经济发展处在极化阶段,空间经济差异水平与经济增长呈正相关关系。同期,新疆经济发展的一级核心区一直是乌鲁木齐,制造业、科学研究技术服务和地质勘查业、交通运输仓储和邮电通信业、批发贸易零售餐饮业、金融保险业和房地产业等是推动一级核心区发展的主要动力行业;二级核心区空间收敛,动力行业由多元化逐渐走向单一化,变成石油采掘业型经济区;边缘区则以农业经济为主。

英文摘要：

This paper analyses of the spatial discrepancy and its change of Xinjiang economical development during 1995-2006 according to approaches of standard deviation,Theil index and elasticity theory,the economical spatial structure and its evolution according to approach of classify analysis and Core-periphery theory,and the mechanim of economical spatial structure evolution according to location quotient approach.The results of the standard deviation and Theil index analysis show that the whole spatial economic discrepancy are increasing during 1995-2006,they are increasing not only inside south Xinjiang and north Xinjiang,but also between north and south Xinjiang,and the whole spatial economical discrepancy is mostly influenced by the inside discrepancy of south Xinjiang,the result of correlation analysis show that spatial economical development is in the stage of congregate development in the same time because the gross domestic product growth is highly correlation to the spatial economical discrepancy,it means the disequilibrium development of regional economy in Xinjiang intensifies with the economy growth.After 15 administrative regions of Xinjiang is used as the spatial unit of classify analysis to study the economical spatial structure of 1995,2000 and 2006,which could be analyses the economic spatial structure evolution characteristics,the industrial location quotient of 15 regions of the three year is counted respectively.The result of those researches show that Urumqi is always the first level core area,with the main dynamic industries of manufacture,transportation Telecommunication,wholesale retail catering,science technology service geological prospecting,financial insurance,real estate,the second level core area is shrinking,which include 6 regions in 1995,3 regions in 2000,and 2 region in 2006.The main dynamic industries of the second core area have changed from polybasic to singularity,as a result,the second level core area is turning to oil exploiting economical area in the same time.The periphery are
