基于相關(guān)—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(xiàn)代港口不僅是全社會運輸流通的中心,也是經(jīng)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(jīng)濟的必然需求,也是為了迎接港口、物流產(chǎn)業(yè)快速發(fā)展挑戰(zhàn)的有力工具。所以,港口物流不僅關(guān)系到港口自身的盈利和發(fā)展,也是全社會關(guān)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(xiàn)狀進行了分析。第二章是港口物流評價指標體系構(gòu)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(jié)論,總結(jié)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(gòu)建了包含20個指標的港口物流評價指標體系。通過相關(guān)性分析,刪除反映信息重復(fù)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(jié)果有重要影響的指標。最終在54個海選指標的基礎(chǔ)上,篩選出了20個評價指標,構(gòu)建了港口物流的評價指標體系。 (2)通過熵權(quán)法對港口物流評價指標進行賦權(quán),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(jù)得分從大到小進行排序,為港口管理部門的決策提供依據(jù)。
[Abstract]:Modern port is not only the center of social transportation and circulation, but also an important part of economic development. The evaluation of port logistics is an inevitable demand of China's market economy and a powerful tool to meet the challenges of the rapid development of port and logistics industry. Therefore, port logistics is not only related to the profit and development of the port itself, but also the focus of the whole society. This paper is divided into four parts, the first chapter is an introduction. This chapter gives the meaning of port logistics, introduces the development process and characteristics of port logistics in China, and analyzes the research status of port logistics evaluation. The second chapter is the principle and method of constructing the evaluation index system of port logistics and the principle and method of establishing the evaluation model of port logistics. In the third chapter, 8 ports such as Shanghai Port, Shenzhen Port and Dalian Port are selected for empirical analysis. Finally, the conclusion is drawn, and the main work and innovative features of this study are summarized. The main work of this paper is as follows: (1) the evaluation index system of port logistics including 20 indexes is constructed. Through correlation analysis, the index reflecting information repetition is deleted to ensure the simplicity and effectiveness of the index system, and the index which has important influence on the evaluation result is retained by principal component analysis. Finally, on the basis of 54 sea selection indexes, 20 evaluation indexes are selected, and the evaluation index system of port logistics is constructed. (2) the evaluation index of port logistics is weighted by entropy weight method, and the evaluation equation of port logistics is established. Through the empirical analysis of 8 ports, such as Shanghai Port and Shenzhen Port, the evaluation scores of these eight ports are calculated and sorted according to the score from big to small, which provides the basis for the decision of port management department.
