Table 1
Summary of previous studies on seaports’ freight demand estimation.
| Study | Type | Predicted variables | Predictor variables |
| Forecasting cargo growth and regional role of the port of Hong Kong [44] | Multivariate regression | Total inward freight movements (million tons) | Electricity demand | Population | Domestic exports at 1990 | Prices |
| Forecasting container cargo throughput in ports [45] | Multilinear regression | Container throughput/traffic (TEU) | Industrial production index, GNP | Elasticity model | GDP per capita for country | Port competition model |
| Estimation of freight demand at Mumbai port using regression and time series models [46] | Univariate and multivariate regression | Freight demand | GDP and crude oil production | World income |
| Forecasting cargo throughput for the port of Hong Kong: error correction model approach [47] | Univariate and multivariate regression | Total freight throughput | China’s total trade value | USA total trade value | Number of berths in container terminal | Cargo throughput at other ports |
