Visualizing the landscape of blue finance for sustainable development: A bibliometric analysis and future directions
Bibliographic record
Abstract
Abstract Blue finance research has recently made significant progress, but comprehensive research is still in its infancy. This paper established a consolidated database of 223 articles on blue finance and used CiteSpace for visualization analysis. Firstly, blue finance develops in embryonic, fluctuating, and stable growth phases. The main research countries are the US, Australia, England, and Canada. The University of California and the University of Queensland are the main research institutions. Marine Policy and Science are highly cited journals. A few core authors shape blue finance research with limited collaboration. Secondly, three themes were established by categorizing ten keyword clusters: financial instruments and mechanisms for marine conservation and sustainability, policy frameworks for adaptation and climate resilience, and policy frameworks for adaptation and climate resilience. Thirdly, contingent valuation, marine protected areas, and the blue economy are the main research hotspots. The results' theoretical contribution is identifying the progress of blue finance and its potential directions. Researchers, managers, and policymakers can use it to promote economic growth and ocean sustainability.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
