摘　　要：以县域为研究单元,运用熵模型、GIS技术、变异系数、改进的锡尔系数分解等方法,对1980-2011年新疆县域经济综合发展水平的空间格局、内部差异演化及其机理做出定量化测度与分析。结果表明:(1)相比全国和西部12省市区,新疆的经济均量水平较低,增量和效益拉动较强;2011年新疆经济发展水平在均量、增量及效益分量中呈现出各自的空间分异特点;自1980年以来新疆区域经济发展的重心不断北移,极化中心基本显现。(2)以变异系数测度的县域经济极化态势呈波动减小特征,且差异大致可以分为4期扩张期和4期收缩期;扩大区域差异贡献率大的因子逐渐从增量和均量转化为增量和效益,资源开发在新疆区域经济发展中的贡献率越来越大。(3)从贡献率的变动趋势上看,南疆内部差异和县域内部差异对新疆整体区域经济差异影响较显著;南疆内部、北疆内部个别年份、县市各自内部的区域经济差异均同新疆的经济总体差异变化规律一致,南北疆之间和县市间的差异对总体差异的贡献率最小,变化振幅亦最小。Selecting county-level administrative districts as the study unit, the quantitative measure and evaluation of economic comprehensive development level concerning spatial pattern, internal differences evolution and the mechanism in Xinjiang from 1980 to 2011 are analyzed in this paper using entropy model, GIS analysis, coefficient of variation and Theil indices. Most of the indicators consist of economic, population, industry, finance, fixed-asset investment, urbanization and so on come from the“Fifty years in Xinjiang （1955 to 2005）”, “Xinjiang Statistical Yearbook”（2006 to 2012）. Through changes in the regional economic differences, the paper analysed the character- istics of economic growth in Xinjiang, the causes existed in regional economic differences, and put forward the corre- sponding countermeasures and suggestions with the purpose of providing beneficial reference for accelerating the de- velopment level of backward areas and maintaining competitiveness in developed areas. The implications from the study are as follows： （1） Compared with the west China and the whole country, the comprehensive economic devel- opment level of Xinjiang is higher than that of the west China and even the whole country, especially the growth ef- fect and the efficiency effect are playing great important roles in improving the comprehensive economic develop- ment level of Xinjiang. In 2011, the level of economic development in Xinjiang exhibit respective space differentia- tion characteristics in mean, increment and effectiveness value; the gravity center of regional economic development moved on and on to the north, and the polarization center appeared basically since the reform period. （2） The county economic polarization evaluated by coefficients of variation is fluctuation decreasing, which can be roughly divided into four expansion stages （1980-1990, 1995-1996, 2001-2004, 2007-2010） and 4 systolic stages （1990-1995, 1996-2001,2004-2005,2010-2011 ） ;Factors for expanding regional differenc
