Abstract
The Belt and Road Initiative (BRI) key element is to accelerate infrastructure investment, which, in turn, improves the connectivity and enhances trade and foreign direct investment of BRI-participating countries. Thus, this study attempts to investigate and compare the impact of infrastructure investment on the economic growth of the African and Asian BRI-participating countries. The results reveal that infrastructure development imposed negative and significant impact on both African and Asian regions' economic growth in the long-run.
