基于ESDA的湖南省县域商业空间集聚分析

Research on Commercial Agglomeration at County Level in Hunan Province Based on ESDA

商业集聚有利于促进区域内商业的有效供给和需求从而带动区域经济的发展,增强区域经济的竞争力。文章以1988～2008年湖南省空间商业数据为基础,利用ESDA方法对湖南省县域商业空间集聚的总体趋势与局部差异进行了探索性研究。结果表明:湖南省商业空间全局集聚不明显,局部商业空间极化趋势显著,并且比较清晰地呈现出"3+5"城市群、大湘西和湘中南三大商业空间集聚区域,长株潭和"3+5"城市群日益成为湖南省商业发展的核心区域。

Commercial agglomeration is a driving force for regional economy by effective supply and demand.The paper uses ESDA to analyze the general tendency of commercial agglomeration and local difference in Hunan Province at county level on the basis of commercial data in1988-2008.The results show that the degree of commercial agglomeration is not obvious in Hunan Province,local polarization trend is significant,and forms a clear ＂3 ＋5＂ city group,the Great Western Hunan,Central Hunan,and Southern Hunan.Chang-Zhu-Tan city group and the ＂3 ＋5＂city group are becoming the core area of commercial development.
