皖江示范区建设以来安徽省经济空间格局演变态势

Evolution analysis of economic spatial pattern in Anhui province after the construction of Wanjiang City Belt

以GIS的空间统计工具为技术手段,以安徽省2009~2016统计年鉴为数据来源,分析安徽省县域经济发展空间格局演变。结果显示:安徽省各县经济发展水平呈现出显著的空间自相关且集聚程度逐渐增强,经济热点区位于皖江示范区范围内,主要分布在合肥市和沿江地区,经济热点区县域数量逐年增多,方向上呈现沿长江自东向西扩展,冷点区空间位置基本不变,主要分布在皖西北的阜阳市。安徽省经济增长总体上呈现随机分布,局部集聚不明显,皖中地区增长率略大。最后,从区位、物质积累、政策、市场发育水平、人才五个方面分析了安徽省经济格局的演变原因。

Taking the GIS spatial statistical tool as the technical means, the paper analyzed the spatial pattern evolution of the county economy in Anhui province by using 2009-2016 statistical yearbook of Anhui province as the data source. The results showed that the economic development level of the counties in Anhui showed a significant spatial autocorrelation and the degree of agglomeration gradually increased. Economic hot spots are located in the scope of Wanjiang City Belt and it is mainly distributed in Hefei, along the Yangtze River. The number of economic hotspots increased year by year in the direction of the Yangtze River from east to west. However, the spatial location of the cold spot is almost unchanged, which is mainly distributed in the northwest of Fuyang. Generally speaking, the economic growth of Anhui province shows a random distribution, and local agglomeration is not obvious. Finally, the paper analyzes the evolution of the economic structure of Anhui province from five aspects： location, material accumulation, policy, market level and talent.
