This paper examines the synergistic relationship between port and urban resilience within the Guangxi port city cluster along the Pinglu Canal. Employing a hybrid methodology integrating factor analysis and the Decision Making Trial and Evaluation Laboratory - Analytic Network Process, the study assesses resilience across economic, social, ecological, and infrastructure dimensions for 11 key port cities. The analysis indicates varying resilience levels, with Nanning, Qinzhou, and Beihai demonstrating higher resilience, while Baise and Hechi require enhancement. The research highlights the significant improvement in port resilience for Nanning due to its strategic role as a transportation hub. The coupling coordination degree model reveals the coordinated development between urban and port resilience, particularly in central cities like Qinzhou and Nanning. The study concludes with strategic insights for bolstering port operational capabilities, enhancing port-city interaction, and establishing comprehensive risk management systems to foster resilience and competitiveness. Limitations are acknowledged, including data timeliness and model assumptions, suggesting avenues for future research on policy interventions and coordinated development strategies.
