Abstract
Since COVID-19, congestion has become an important factor that can hinder the efficient operation of ports and cause direct and indirect economic damages. Therefore, this study conducted an SBM-DEA analysis with congestion as a undesirable output variable to investigate the impact of congestion on the efficiency of four Korean ports (Busan, Yeosu-Gwangyang, Ulsan, and Incheon) before and after COVID-19. The analysis revealed that the overall efficiency of the ports was lower after the outbreak of COVID-19 than before, and that the efficiency of each port was relatively different depending on its infrastructure and budget. This analysis shows that port efficiency is being negatively affected by congestion both pre- and post- COVID-19. Additionally, port infrastructure and budgets have a direct impact on congestion levels. To enhance port efficiency, it's important to implement appropriate systems and policies to manage congestion while considering the unique characteristics of each port.
