Abstract: Within the entire maritime logistic chain, the landside portion between ports and hinterlands, namely, the port-hinterland container transportation network (PHCTN), serves as an essential link. However, under the risk of unconventional emergency events (UEEs), the ability of PHCTNs being robust against and adaptive to potential disruptions is a prerequisite to ensure the efficiency of the international container transportation. Specifically, we carried out two studies. The first study aims to investigate the strategic investment of players in a PHCTN to enhance network resilience to man-made UEEs in the pre-event period by reducing network vulnerability. Given the complexity of the involvement of multiple players and their interactin g complementary and competitive business relationships, network game theory is adopted. Results show that the complementary influence Bonacich centrality of players plays a critical role in determining their investment decisions and serves as basis for useful managerial insights. The second study constructs an integer programming model to investigate the influence of immediate recovery activities on the improvement of PHCTN resilience from the perspective of shippers by focusing on the post-event period of UEEs. The validity and reliability of the model is tested by using a numerical simulation based on the specific case of Gothenburg Port and part of its hinterland. Some useful implications to improve the resilience of PHCTN in the post-event period are provided.
