| Summary: | Global economic integration has accelerated frequency of trade between different countries and promoted logistics industry to quickly become another development highland. Facts have proved that logistics has been separated from production and circulation as an independent link, driven by existing technology and demand, and with its characteristics and needs of the times, logistics has formed a strong professional field. At the same time, it can also independently undertake corresponding brokerage business activities in trade exchanges. To better understand the role of port and logistics in trade, it is particularly necessary to study port logistics informatization. Considering efficiency of input and output, more attention should be paid to performance evaluation of port logistics informatization construction. Based on analysis of port logistics informatization development, evaluation index system and DEA evaluation model which can represent performance of port logistics informatization were constructed. 17 listed ports in China were taken as examples for empirical study, and suggestions for development of port logistics informatization are put forward. Results show that among 17 ports, only Tangshan port, Shenzhen port, Yantian port and Chongqing port have a technical efficiency value of 1, while the other 13 ports have a certain degree of redundancy in technical efficiency value of information input, indicating that development and construction of port logistics informatization has a very important impact on port logistics income. Efficiency value of average annual net profit indicates that the port has redundant investment in information construction, which means that construction of port logistics informatization can not only blindly pay attention to informatization input, and that shortage of informatization output will be affected by other factors to a certain extent. The more investment in informatization construction is not the better, and different ports are affected by different types of factors. Therefore, it is necessary to combine actual development status of ports and to apply right medicine to avoid insufficiency or redundancy of port input, to realize optimal investment strategy for informatization construction of port logistics. Through this study, it is expected to achieve the purpose of systematically sorting out, concluding and expanding relevant theories of port logistics informatization construction, clarifying management problems that need to be solved, indicating methods for promotion of informatization construction, and providing new ideas and reference basis for reform, transformation and upgrading of port enterprises. © 2023, Strojarski Facultet.
