摘要
以2008-2017年安徽省县域人均GDP数据为研究指标,运用探索性数据分析(ESDA)、变异系数、泰尔指数、相对发展率等方法,从时间和空间两个维度,对安徽省县域经济差异的时空格局进行分析。结果表明:安徽省县域经济绝对差异逐年扩大,相对差异波动性缩小,其中皖中地区内部经济差异最为显著;县域经济自2008年开始出现微弱的空间集聚态势,且波动性增强,发达县域主要分布在皖江城市带范围内,欠发达县域主要分布在皖北地区和皖中、皖南的西部地区,两级分化趋势有所增强;局部空间自相关分析发现,高高集聚区主要位于皖江城市带中个别县域,低低集聚区主要位于西北部地区。
This paper takes the per capita GDP of counties from 2008 to 2017 as the research index;adopts the method of ESDA,coefficient of variation,Theil index and Nich index,and analyses the spatial-temporal pattern and evolution trend of county economic differences from two aspects including time and space.The results show that:the absolute difference of county economy is expanding each year while the relative difference is shrinking in the volatility.There has been a weak trend of spatial agglomeration of county economy since 2008,and increased volatility.Developed counties are mainly distributed in Wanjiang City Belt,while underdeveloped counties are mainly distributed in north,the west of middle and south of Anhui Province.The polarization phenomenon show an increasing trend.Local spatial autocorrelation analysis shows that the HH agglomeration areas are mainly located in Wanjiang City Belt,while the LL agglomeration areas are mainly located in the northwest of Anhui Province.
