This study applies bibliometric and textual analysis to examine the growth and thematic orientation of Green Finance research. Citation analysis reveals increasing scholarly interest, with China emerging as the leading contributor in terms of publications, citations, and collaborative strength. Influential works highlight how Green Finance supports renewable energy adoption, technological innovation, and productivity improvements. Key publication platforms include Environmental Science and Pollution Research and Energy Economics, which have become central outlets for advancing the field. Textual analysis identifies six thematic clusters: foundational concepts (green credit, green economy), policy frameworks (SDGs, financing mechanisms), practical applications (innovation zones, reforms), methodological approaches (natural experiments, high-quality development), technological transitions (low-carbon economy, digitalization), and financial instruments (green bonds, sustainable investment). The recurring focus on carbon emissions, renewable energy investment, and sustainable investment highlights the field’s strong alignment with global sustainability priorities. Overall, the findings demonstrate that Green Finance has matured into a multidisciplinary research domain. Future opportunities lie in diversifying regional contributions, expanding methodological approaches, and strengthening cross-disciplinary integration to enhance its role in achieving sustainable development.
