摘要

本研究以长江港口体系为例,探讨了内河港口体系中门户海港对内陆港口的影响。研究首先采用固定效应面板模型证实了上海港对长江内河港口的整体积极影响。随后,本研究利用具有个体特定斜率的面板数据模型,揭示了上海港对每个内河港口的积极影响,但这种影响的程度存在显著差异。研究进一步采用面板阈值回归模型,从地理距离、运营距离和经济距离三个方面剖析了上海港对内陆港口的影响机制。在地理距离方面,上海港对长江内河港口吞吐量的影响随着通航距离的增加而减弱。值得注意的是,位于长江下游的内陆港口受到的影响最早也最大,这标志着下游地区在港口区域化进程中的影响较早。在作业距离方面,上海港对吞吐量较高的内陆港口的影响要大于吞吐量较低的内陆港口。在经济距离方面,与经济欠发达地区的内陆港口相比,经济发展水平较高的城市的内陆港口受上海港的影响较小。这种细致入微的理解为了解主要门户港口与内陆港口之间的相互联系提供了宝贵的见解。

Examining the influence mechanisms of gateway ports on inland ports in the context of Port regionalization - A case study of the Yangtze River Port system

This study examines the influence of gateway seaports on inland ports within a river port system, focusing on the Yangtze River port system as a case study. The research initially employs a fixed-effects panel model to confirm the overall positive impact of Shanghai Port on Yangtze River inland ports. Subsequently, using Panel data model with individual-specific slopes, this study reveal that Shanghai Port positively affects each inland port, but the magnitude of this impact varies significantly. The research further employs a panel threshold regression model to dissect the mechanisms through which Shanghai Port influences inland ports in terms of geographical, operational, and economic distances. In terms of geographical distance, the influence of Shanghai Port on the throughput of Yangtze inland ports diminishes as the navigational distance increases. Notably, inland ports located downstream on the Yangtze River are the first and most impacted, marking the downstream area as an early influencer in the port regionalization process. As to operational distance, Shanghai Port exerts a stronger influence on inland ports with higher throughput levels, as opposed to those with lower throughput. With respect to economic distance, inland ports in cities with higher economic development are found to be less influenced by Shanghai Port compared to those in less economically developed regions. This nuanced understanding provides invaluable insights into the interconnectedness of major gateway ports and their inland counterparts.

期刊介绍: Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
