上市公司业绩的分类与评价摘要本文用多元统计分析方法对金融板快的28家上市公司业绩进行分类并给出评价。首先选取每股收益、净资产收益率、净资产增长率、主营业务收益率等11项指标作为业绩评价因子，采用快速聚类法将这些上市公司分为5类。其中第一类和第二类包含上市公司较少，因此可直接对其进行判断，对另外三类上市公司采用主成分分析法进行排序和评价，得出了三个最具投资价值的上市公司。本文研究成果对价值投资者具有一定的参考价值。关键词：主成分分析；上市公司；经营业绩；快速聚类法；评价TheperformanceoflistedcompaniesintheclassificationandevaluationAbstractInthisarticle,28listedcompaniesofthefinancialplateareclassifiedandevaluatedwiththemethodofmultivariatestatisticalanalysis.Firstchooseearningspershare,netassetsyieldandmainbusinessgrowthandyieldof11indexesasaperformanceevaluationfactors,therapidclusteringmethodwillbedividedintofivetypesofthelistedcompany.Thefirstclassandsecondclassincludeslistedcompanies,solessdirectlyonthejudgment,foranotherthreelistedcompaniesusingprincipalcomponentanalysisandevaluation,rankingthethreemostinvestmentvalueoflistedcompaniesinvalue.Thisresearchhasthecertainreferencevaluetoinvestors.Keywords:PrincipalComponentAnalysis;ListedCompanies;OperatingPerformance;RapidClusteringMethod;Evaluation目录论文总页数：28页1引言.....................................................................11.1本课题研究背景和意义....................................................11.2本课题的研究方法........................................................12评价指标的选取.............................................................12.1上市公司相关知识简介....................................................12.2上市公司的评价指标......................................................23聚类分析和主成分理论简介....................................................23.1聚类分析的基本概念......................................................23.2快速聚类法..............................................................33.2.1选择聚点............................................................33.2.2快速聚类法的步骤....................................................43.3总体主成分概念........................................................53.4总体主成分的求法........................................................54实例应用....................................................................64.1问题的提出..............................................................64.2模型的建立..............................................................64.2.1对公司进行分类......................................................64.2.2对五类公司分别评价..................................................74.3模型的求解..............................................................84.3.1聚类分析模型求解....................................................84.3.2对不同类公司的股票进行评价及分类...................................104.4结果分析...............................................................165改进建议及措施.............................................................17参考文献.....................................................................18致谢.....................................................................19声明.....................................................................20附录：...................................................................211引言1.1本课题研究背景和意义我国证券市场是我国快速发展...
