Abstract

Blue Finance has rapidly emerged as a strategic frontier for channeling capital toward sustainable and resilient ocean economies, connecting financial innovation with environmental governance and climate responsibility. However, its conceptual foundations remain fragmented, hindering theoretical integration and policy application. This study conducts a comprehensive bibliometric and science-mapping analysis of 217 Scopus-indexed publications (2007–2025), using Biblioshiny (Bibliometrix v4.2.2), VOSviewer v1.6.20, and Gephi v0.10.1 to trace the intellectual evolution, thematic configuration, and research agenda of Blue Finance. The analysis reveals a rapidly consolidating field that has evolved through three distinct phases, anchored in sustainability science but constrained by limited financial integration. The field’s cognitive structure is organized around three interlinked pillars: the climate–environmental interface, sustainability integration and governance, and innovative financial mechanisms enhancing economic resilience. Emerging research hotspots in blue bonds, sustainable finance, and blue justice signal a paradigm shift from normative ecological awareness to actionable, market-aligned resilience. The findings outline a forward-looking research agenda that strengthens theoretical consolidation, governance accountability, and sustainable investment frameworks. This study offers strategic guidance for researchers, investors, and policymakers, positioning Blue Finance as a transformative catalyst that unites innovation, resilience, and equity in shaping the future of sustainable finance.
