摘　　要：基于2000—2014年江西省91个县域人口经济数据,利用标准差与加权变异系数、Arc GIS空间自相关、Theil指数及分解等方法分析了江西经济差异格局演变。结果表明:(1)绝对差异显著扩大,相对差异先扩大再缩小。(2)以浙赣铁路、沪昆高速沿线为界的北高南低长期稳定,仅在南昌、新余出现高高集聚,九江和景德镇出现高低集聚。(3)Theil指数显示,尺度越小,区域差异越大。(4)赣北区域差异最大但逐步缩小,赣东北和赣西呈先扩大后缩小,赣中南差异很小;一阶分解中市域和县域对总体差异贡献率分别达65.72%和83.85%;二阶分解中县域的市内差异与市间差异相近,分别为45%、40%。演变原因可概括为:自然历史条件是先天塑造力,经济结构水平是主要决定力,区域发展政策是强大推动力。This paper investigated the regional inequality in Jiangxi Province, with the Theil index decomposition and the spatial analysis, usingdata of 91 counties from 2000 to 2014. The conclusions were drawn as follows：The characteristics of relative temporal change fluctuated, expandingbefore 2004, shrinking 2004 - 2009 and the inverted ＂U＂ type change after 2009. Inequality was sensitive to scale, inter- county inequality was thewidest. Using Theil index, the average inequality contribution was 65.72 % in municipalities, but 83.85 % in counties. The spatial change was rela-tively stable, high - high aggregation appeared in Nanchang, Xinyu and high - low aggregation in Jiujiang, Jingdezhen. Finally, summaried the influ-ence factors：The congenital shaping force was natural history condition, the mainly decided force was economic structure level and powerful drivingforce was regional development policy.
