基于PCA的南通港港口物流竞争力评价研究摘要随着经济的不断全球化，现代物流已经从国内走向国际，而港口的结构体系也随之在不断的改变中，因此，对于南通港来说这既是机遇又是挑战。本文先对港口物流竞争力的影响因素进行探讨，在此基础上构造港口物流竞争力评价指标体系，再对南通港港口物流的现状进行总的概括，然后结合SPSS软件使用PCA法对南通港和长三角沿海港口就建立的指标来评价研究，分析出南通港港口与长三角沿海港口相比的竞争力水平，最后提出了一些使南通港港口物流竞争力提升的措施。【关键词】南通港；港口物流；主成分分析法StudyonEvaluationofNantongPortLogisticsCompetitivenessBasedonPCAAbstractWiththecontinuouseconomicglobalization,modernlogisticshasfromdomestictointernational,andtheportstructuresystemisintheconstantchange,therefore,fortheportofNantongisbothanopportunityandachallenge.Thispaperfirstdiscussesthefactorsaffectingthecompetitivenessoftheportlogistics,portlogisticscompetitivenessevaluationindexsystemisconstructedonthebasisofthis,againthecurrentsituationofNantongportlogisticsforthetotalsum,andthenusethePCAmethodtoNantongportandtheYangtzeRiverDeltacoastalportontheestablishmentoftheindicatorstoevaluatetheresearchwithSPSSsoftware,analysisofNantongportcomparedwiththeYangtzeRiverDeltacoastalportcompetitiveness,andfinallyputsforwardsometoNantongEnhancetheportlogisticscompetitiveness.[Keywords]Nantongport;Portlogistics;Principalcomponentanalysis目录一、绪论..........................................................................................................................................1（一）研究背景、目的与意义...............................................................................................1（二）国内外研究综述..........................................................................................................1二、港口物流竞争力评价指标的建立...........................................................................................3（一）港口物流竞争力影响因素分析...................................................................................3（二）建立港口物流竞争力评价指标...................................................................................4三、基于PCA的南通港港口物流竞争力评价...............................................................................5（一）南通港港口物流概况...................................................................................................5（二）PCA主成分分析原理....................................................................................................5（三）南通港港口物流竞争力评价.......................................................................................6（四）南通港港口物流竞争力评价结果分析.....................................................................11四、南通港港口物流竞争力提升措施.........................................................................................12（一）江海并举，整合岸线资源.........................................................................................12（二）加强国际交流合作，促进进出口额.........................................................................12（三）加大万吨级及集装箱泊位建造.................................................................................13（四）加快12.5米深水航道的建设...................................................................................13（五）注重港间协调，实行一体化管制..........................
