对于严重依赖进出口的工业来说，海港运营非常重要。港口风险的可靠评估对于管理海运的正常运行，从而管理工业经济至关重要。港口等贸易便利设施一旦出现故障，将影响行业供应链的畅通。由于港口与产业集群之间的关系复杂，对港口中断对产业造成的经济损失进行评估是一项具有挑战性的任务。本研究旨在建立一个系统的框架，对港口中断造成的产业集群的经济损失进行评估。整个风险评估分为三个阶段，重点是建立网络流模型、经济评估和评估风险缓解策略。并以深圳港及其相关制造业为例进行了实证研究。制造商采用的动态库存控制策略有利于降低港口中断风险。
Seaport operations are highly important for industries which rely heavily on imports and exports. A reliable evaluation of port risks is essential to govern the normal running of seaborne transportation and thus the industrial economies. The occurrence of a breakdown in the trade facilitators, such as ports, will disrupt the smooth flow of supply chains for the industries. The estimation of the economic loss for an industry when a port gets disrupted is a challenging task as the relationship between the port and industry clusters is complex. This study aims to develop a systematic framework for performing economic loss estimation of industry clusters due to port disruptions. The whole risk assessment is split into three stages focusing on the establishment of a network flow model, economic estimations and evaluating risk mitigation strategies. The proposed idea is demonstrated by a case study on Shenzhen port and its related manufacturing industries. A dynamic inventory control strategy used by manufacturers is found to be beneficial for mitigating port disruption risks.
