%A Xiao Bian %L theses_frw4738 %T Port Sustainability: A Comparative Analysis of Global Initiatives and Their Efficacy Using Crisp-Set Qualitative Comparative Analysis %X Seaports play a crucial role in global trade and transportation networks, significantly contributing to regional economic performance. However, the rapid urbanization and population growth in coastal port cities have raised global concerns about sustainable development. This study addresses these concerns by conducting a comparative analysis of global port sustainability initiatives using Crisp-Set Qualitative Comparative Analysis (csQCA). The research evaluates 310 port sustainability initiatives across six conditions: digitalization, environmental caring, community building, sustainable infrastructure, health safety and security, and climate and energy measures. The study aims to identify which combinations of these conditions most effectively enhance port sustainability. The findings reveal that no single condition is necessary for sustainability; rather, multiple pathways involving different combinations of conditions can lead to sustainable outcomes. The analysis also underscores the importance of regional contexts in shaping the effectiveness of these initiatives. For instance, ports in developed regions such as Europe and North America show higher sustainability performance compared to those in developing regions like Asia, Africa, and South America, due to differing economic conditions, regulatory environments, and technological advancements. This research fills existing gaps by providing an integrated approach that combines economic, social, and environmental aspects to evaluate port sustainability comprehensively. It offers actionable insights and practical recommendations for policymakers, port authorities, and stakeholders involved in maritime logistics and port management, aiming to develop more sustainable and resilient port systems. Ultimately, this study contributes to the broader goal of achieving balanced growth through integrated environmental protection and social equity in port cities. %D 2024
