基于相關—主成分分析的港口物流評價研究
發(fā)布時間：2018-07-13 11:47
【摘要】：現代港口不僅是全社會運輸流通的中心,也是經濟發(fā)展的重要組成部分。對港口物流進行評價研究是中國市場經濟的必然需求,也是為了迎接港口、物流產業(yè)快速發(fā)展挑戰(zhàn)的有力工具。所以,港口物流不僅關系到港口自身的盈利和發(fā)展,也是全社會關注的一個焦點問題。 本論文共分為四個部分,第一章是緒論。本章給出了港口物流的含義,介紹了中國港口物流的發(fā)展歷程和特點,并對港口物流評價的研究現狀進行了分析。第二章是港口物流評價指標體系構建的原理及方法和港口物流評價模型建立的原理和方法。第三章是選取了上海港、深圳港、大連港等8個港口為實證對象進行實證分析。最后是結論,總結了本研究的主要工作和創(chuàng)新特色。本文的主要工作如下： (1)構建了包含20個指標的港口物流評價指標體系。通過相關性分析,刪除反映信息重復的指標,保證指標體系的簡潔有效；通過主成分分析,保留了對評價結果有重要影響的指標。最終在54個海選指標的基礎上,篩選出了20個評價指標,構建了港口物流的評價指標體系。 (2)通過熵權法對港口物流評價指標進行賦權,建立了港口物流評價方程,并對上海港、深圳港等8個港口進行實證分析,計算這8個港口的評價得分,并根據得分從大到小進行排序,為港口管理部門的決策提供依據。
[Abstract]:Modern port is not only the center of the whole society transportation circulation , but also an important part of the economic development . The evaluation research on port logistics is the inevitable demand of the market economy of China , and it is a powerful tool to meet the rapid development challenge of port and logistics industry . Therefore , the port logistics not only relates to the profit and development of port itself , but also a focus problem of the whole social concern .
This thesis is divided into four parts , the first chapter is Introduction . This chapter gives the meaning of port logistics , introduces the development course and characteristics of port logistics in China , and analyzes the present situation of port logistics evaluation .
( 1 ) A port logistics evaluation index system with 20 indexes was constructed . Through the correlation analysis , the indexes reflecting the duplication of information were deleted , and the index system was simple and effective ;
Based on the 54 indexes , 20 evaluation indexes were selected , and the evaluation index system of port logistics was constructed .
( 2 ) The port logistics evaluation index is weighted by the entropy weight method , the port logistics evaluation equation is established , and the eight ports , such as Shanghai Port and Shenzhen Port , are empirically analyzed , the evaluation scores of the eight ports are calculated , and the basis is provided for the decision of the port management department according to the ranking from the big to small .
