Summary

      The outbreak of COVID-19 has affected the efficiency of port operation, and caused port closures, delays in shipping schedules, resulting in port congestion and cancelling of port calls. Such situation has rapidly spread across the world, disrupting sailing schedule.
       This study aims to explore the impact on container ports caused by the COVID-19. The study organizes actual route data to classify the container network according to ship types: all ship types network, Very Large Container Vessels network, Large Container Vessels, and feeder network. The study uses social network analysis to calculate the centrality index and hub and authority degree of container ports along the Far East-North America and Far East-Europe routes. Finally, we analyze the evolution of container ports in these three regions before and after COVID-19.
       According to the results, compared with 2019, since the outbreak of COVID-19 in 2020, the degree centrality, betweenness centrality, hub authority and authority of ports all showed a downward trend. Until the post pandemic era (2021), although the centrality index of ports in some regions (such as China) have gradually improved than in 2020, the value is still lower than in 2019. Although the pandemic has a significant impact on shipping, the results shows that Shanghai, Singapore, Busan, Hong Kong, Ningbo still maintain their position as important international ports. In addition, in different ship types, the ports of Singapore, Hong Kong, Shanghai and Busan ranked in the top five in all ship types network, Very Large Container Vessels network, Large Container Vessels, and feeder network., while ports of Kaohsiung, Ho Chi Minh City, Laem Chabang, and Kwangyang are mainly ranked higher in feeder network than in other network.
