1、安徽省各市经济发展的聚类分析段凤君(安徽师范大学，芜湖市241000)关键词：区域差异；主成分分析；指标体系；聚类分析摘要：本文着力于实现对安徽省各市按其经济发展水平进行聚类，以本省17个市为研究对象，选取衡量地区经济发展状况的经济规模、经济结构、居民生活水平、对外经济贸易及科学教育水平5个方面共14项指标，建立相应的统计指标体系。首先，为遵循选取指标体系时的无重复性原则，本文对14项指标进行了主成分分析，得出14项指标中可以提取出3个主成分，其累积方差贡献率达93.486%。其次，借助主成分函数给出
2、了综合评价函数，对本省17个市进行了综合评价，并给出了排序。最后，借助各市的主成分得分、依据多元统计分析中的聚类分析方法，对17个市进行了聚类分析，最终将17个市分成5类地区，并结合分类结果提出了一些促进本省经济发展、缩小省内市间发展差异的建议。TheClusterAnalysisoftheEconomicGrowthofEachCityinAnhuiProvinceFengjunDuan(AnhuiNormalUniversity,Wuhu241000)Keywords:Regionaldiffer
