以香港为实证对象,计算其港口空箱吞吐量与对外贸易主要经济指标的相关系数,并采用岭回归预测方法,进一步分析、探讨了不同贸易方式的总额和货量对空箱吞吐量影响程度的差异性。研究结果表明,香港港口空箱吞吐量与该地区对外贸易额、对外贸易货量具有强相关性,并且香港的本地产品出口额和出口货量对空箱吞吐量的影响远大于进口和转口部分。
Taking Hong Kong as an example, we calculated the correlation coefficient between the port empty container throughput and the main economic indicators of foreign trade and adopted the ridge regression prediction method to further analyze and discuss the impact of the total amount and volume of different modes of trade on the empty container throughput The difference. The results of the study show that the throughput of empty containers at Hong Kong’s port has a strong correlation with the volume of foreign trade and foreign trade in the region and the impact of Hong Kong’s exports of domestic products and export volume on the throughput of empty containers is far greater than that of the import and re-exports .
