As the central knot of global logistics supply chain,a port is involved in logistics services in various ways.Developing port logistics becomes the first choice of many coastal ports of China to enhance their comprehensive competitiveness.This paper studies the concept of port logistics’comprehensive service level,puts forward the structure framework of port logistics’comprehensive service level,and establishes an evaluation index system and model for port logistics’comprehensive level of coastal port based on fuzzy element theory.Furthermore,the application and comparison research are carried out for the typical coastal port of Chinese mainland.The empirical study results show that the fuzzy matter-element theory used for the evaluation of coastal ports’logistics comprehensive service level is very effective,and this evaluation method combined qualitative and quantitative analysis is very practical and simple.The conclusion of evaluation is objective and reasonable,which is helpful for improving the service-environment construction of the main coastal port of Chinese mainland.
