This study presented a theory-informed bibliometric review that explored the intersection of adaptation finance, vulnerability, and development cooperation within the climate finance literature. Anchored in the vulnerability-resilience framework, the study aims to map the conceptually-aligned financial models on adaptation, particularly how policy-driven instruments such as Official Development Assistance (ODA) have evolved within the world economy and debates about global macroeconomic policy. Utilizing a conceptually integrated search strategy, the analysis combined bibliographic coupling, thematic clustering, and theory-informed mapping techniques. The findings revealed that although adaptation-related concepts held a central place in global policy frameworks (e.g., Sustainable Development Goals (SDGs) 13 and 17), their representations in the academic literature remained uneven and fragmented. Structural clusters reflected the dominance of Global North institutions and mitigation-centered research whereas emerging thematic patterns indicated growing emphasis on context-specific and vulnerability-sensitive adaptation finance. Comparative insights from sectoral ODA data confirmed the thematic gaps identified in the bibliometric analysis and underscored the persistent disconnect between financial flows and local adaptation needs. By linking bibliometric insights with patterns of institutional finance, this study offered an integrative perspective on climate-oriented development and contributed to the agenda of global economic transformation. In doing so, it addressed a significant research gap via combining integrated theory-driven bibliometric mapping with analysis of policy-centered development finance.
