[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.
