This research examines the relationship among ASEAN+3 countries from 2000 to 2014 based on Cobb-Douglas theoretical framework. The results show that financial depths measured by domestic credit to private sector, M3 and stock market capitalisation all have significant effects on economic growth. The paper also gives policy recommendations to promote financial development for purposes of long-term economic growth in ASEAN+3 countries. | Financial depth and economic growth: Empirical evidence from ASEAN+3 countries
