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. Conversely, the findings reveal a bi-directional Granger causality between economic growth and infrastructure development in both African and Asian regions in the short run. Nevertheless, the accumulation of capital formation only imposed a significant positive impact on the economic growth of the Asian region. As a result, policymakers from each region could exchange ideas on spurring economic growth of respective regions. However, they should formulate different policies to reap the BRI benefits.
