摘要: 正确预测港口集装箱吞吐量对于港口规划设计及国家经济科学发展具有重要意义。为降低预测误差、提高预测精度,笔者构建了引入逻辑斯蒂增长模型的多因素动态生成系数法,充分发挥该模型处理复杂系统行为能力强的优势。结合天津港、上海港及青岛港的历史数据,对2005至2018年的港口集装箱吞吐量进行了预测研究。研究结果表明:逻辑斯蒂增长模型可提高中长期预测精度,预测结果较为理想;利用修正后的模型方法对未来十年天津港集装箱吞吐量进行了再次预测,研究结果对区域港口规划布局具有一定的参考价值;此外,逻辑斯蒂增长模型应用范围不仅限于集装港口的预测,对于与GDP相关的城市总体规划的人口规模、环境承载力、产业增长等多方面的预测均有较高的利用空间。

Abstract: It is of great significance to predict the port container throughput correctly for port planning and design as well as the development of national economics and science. In order to reduce the error and improve the accuracy of prediction, a multi-factor dynamic generation coefficient method combined with logistic growth model was established, which fully utilized the advantages of the model in dealing with the behavior of complex systems. The prediction studies of port container throughput from 2005 to 2018 were carried out according to the historical data of Tianjin Port, Shanghai Port and Qingdao Port. The research results show that: the proposed logistic growth model can improve the medium and long-term prediction accuracy, and the prediction results are ideal. The container throughput of Tianjin Port in next decade is predicted again by using the modified method, which provides a certain reference value for regional port planning and layout. In addition, the application scope of logistic growth model is not only limited to container port prediction, but also has high utilization space for the prediction of population size, environmental bearing capacity, industrial growth and other aspects of urban total plan related to GDP.

Key words: traffic and transportation engineering, throughput, middle/long term prediction, logistic model, generation coefficient method
