The Interplay between Urbanization and Blue Economy Development: A Comprehensive Analysis and Policy Implications

Abstract:

This study conducts a comprehensive exploration of the multifaceted interplay between urbanization and blue economy development, with a focus on global coastal regions and representative case studies across different economic and institutional contexts. By integrating quantitative analysis (panel data from 2018–2023 covering 15 coastal economies) and qualitative research (in-depth policy text analysis and stakeholder interviews), it examines how urbanization dimensions—including population concentration, infrastructure expansion, economic agglomeration, and digital transformation—shape the structure, efficiency, and sustainability of blue economy sectors (marine fisheries, offshore energy, marine tourism, and maritime logistics). The research identifies three distinct interaction patterns: “synergistic growth” (e.g., technology-driven coastal cities in East Asia), “conflict-dominated” (e.g., over-urbanized coastal zones in Southeast Asia), and “transition-oriented” (e.g., resource-rich regions in the Middle East). It further reveals that institutional coordination, ecological regulation, and technological innovation are critical mediating factors in balancing urbanization momentum and blue economy sustainability. Policy recommendations emphasize building region-specific governance frameworks, promoting green urban-coastal integration, and strengthening international knowledge sharing to unlock the synergistic potential of urbanization for blue economy development.​
