摘　　要：针对港口集装箱吞吐量预测中重要指标难以选取的问题,从可能影响港口集装箱吞吐量的因素出发,采用主成分分析法,提取最关键影响因素。分别选取我国三大区域中的上海港、青岛港和广州港进行实证分析。这些影响指标的提取,将为三大区域构建港口集装箱吞吐量预测模型提供重要参考。In view of the difficulties in identifying major factors for port containers throughput forecasting, based on the factors af- fecting the port container throughput, key factors were found by adopting the principal component analytical method. The three biggest ports in our country Shanghai, Qingdao and Guangzhou ports were selected to make some empirical analysis. The extraction of the affecting indicators will provide some insights into developing models to forecast port container throughput.
