Abstract: Current studies on container throughput forecasting are mainly focused on independent forecasts of individual ports, neglecting the deep underlying correlation between the ports and thus may lead to large errors of the prediction. To overcome the weaknesses, this paper proposes a new container throughput forecasting method to systematically forecast the correlated ports. A systematical forecasting model (SFM) is established based on the correlation between the ports identified by the Granger causal test and estimated using the method newly proposed in this paper. For verification purposes, multiple forecasting models, including the newly proposed SFM and the independently forecasting models, are constructed and compared in terms of the forecasting performance based on the monthly container throughput data of Shenzhen port and Hong Kong port, the empirical results show that the new model is superior to its rivals in terms of absolute prediction accuracy and direction accuracy.
