| 摘 要： | 选择安徽省2001-2010 年县域人均GDP为研究指标,综合运用G指数、经济重心、标准差椭圆以及灰色G(1, 1)模型对县域经济的空间演化进行分析预测,最后结合位序规模原理,对空间差异的机理进行分析.总体上安徽县域经济表现出微弱的空间集聚分布态势,呈现出“南北低中间高”、“西低东高”的空间分布格局.县域经济重心在117.57°~117.6°E,31.67°~31.76°N之间变动,有向东南方向移动的趋势.标准差椭圆总体上变化幅度不大,基本上以省会经济圈为核心,范围覆盖了皖江城市带大部分地区,县域经济的空间分布呈现出西北—东南格局,并且这种格局有向正北—正南方向转变的趋势.安徽县域经济满足位序规模原理,其发展状况呈低水平分散均衡型.资源禀赋与交通区位、中心城市发展状况、区域政策是导致安徽省县域经济空间差异的主要原因.

| Abstract: | By selecting per capita GDP of every county in Anhui Province from 2001 to 2010, comprehensively using the methods of G index, economic gravity centre, standard deviational ellipses and G(1, 1) prediction model, this article analyzes and forecasts the evolution of county economy, and, combined with the rank-size principle, analyzes the mechanism of spatial differences. Generally speaking, the county economy of Anhui Province presents a weak clustering distribution trend and shows a spatial pattern of "low in the north and south but high in the middle" and "low in the west but high in the east". The scope of economic gravity centre is 117.569°~ 117.598°E, 31.672°~31.760°N, and has the trend moving to the southeast. The change of standard deviational ellipses is very small; basically the core is capital economic circle, covering the most areas of Wanjiang City Belt. The spatial distribution of county economy presents a "northwest-southeast" pattern, and has the trend changing to "north-south" pattern. The county economy meets the rank-size principle and performs a low-level decentralized equilibrium pattern. Regional resources endowments and location, the development of central cities, and policies are the main reasons that cause the spatial differences. |
