安徽省县域经济差异及空间格局演变研究

Research of Regional Differences and Spatial Pattern of County-level Economy in Anhui Province

县域经济是区域发展的重要基础,也是实现优质均衡的关键因素。文章选取2006-2015年的人均国内生产总值数据,运用泰尔指数模型和探索性空间数据分析方法,对安徽省县域经济的区域差异与空间格局进行实证分析。研究发现:全省县域经济发展水平整体呈现西北低、东南高的态势,合肥及皖南沿江区域是全省经济的增长极;县域经济差异在逐年扩大,北中南三大区域内的差异远大于区域间的差异,其中,皖中地区内部差异急剧扩大,是影响全省总体差异的主要原因;县域经济发展存在显著的空间正相关关系,经济发展水平相似的县在空间上趋于集聚,高水平集聚区位于合肥及沿江区域,低水平集聚区位于皖西北地区。

County-level economy is the important basis of regional development and the key factor to realize high quality balanced devel-opment. This research, selecting the data of per capita GDP from 2006 to 2015, empirically analyzes the regional differences and the spa-tial pattern of county-level economy in Anhui province by applying the methods of Theil index decomposition and ESDA. The results areas following： The degree of county-level economy is higher in Southeast and lower in Northwest in Anhui province, Hefei city and the ar-eas along the Yangtze River are becoming the economic growth pole; The degree of inequality of county-level economy development in theprovince is increasing, and the differences between the three major regions of North, South and central Anhui province are far greater thanthe differences inside each region. Among them, the rapid increase of internal differences in central province is the main reason for theoverall differences in the province; There is a significant positive spatial correlation between the development of county-level economy,the counties with similar level of economic development have a trend of spatial agglomeration. The high level agglomeration mainly ap-pears in Hefei city and the areas along the Yangtze River, and the low level agglomeration mainly appears in northwest Anhui province.
