The study looked at how green finance, capital formation, and government spending on education affect the economic development of ASEAN countries. Data from central banks and the World Bank between 2008 and 2019 was analyzed. The results showed that green finance, capital formation, and educational expenditures have a positive impact on the economic development of ASEAN countries. The study suggests that using multiple data sources and considering a broader range of economies could improve the accuracy and generalizability of the findings.
