Financing sustainable development goals in Sub‐Saharan Africa: Does international capital flows matter?

This study investigates the role of international capital flows in financing the Sustainable Development Goals (SDGs) in Sub‐Saharan Africa (SSA). Using data from 41 SSA countries from 2000 to 2018 and employing the System Generalized Method of Moments (System GMM), the research examines the impact of Foreign Direct Investment (FDI) and remittances on the SDGs across disaggregated levels (economic, social, and environmental sustainability) and the aggregated level (SDGI). The findings underscore the crucial significance of international capital flows as essential financing sources for SSA countries. FDI emerges as a contributor to economic and social sustainability at the disaggregated level, yet it exhibits negative effects on environmental sustainability. Conversely, remittances are shown to positively contribute to economic and social sustainability at the disaggregated level. However, the impact of international capital flows on the aggregate SDGI is found to be insignificantly positive. These results highlight the necessity for policymakers in SSA to devise strategies that maximize the benefits of FDI while addressing its adverse effects on environmental sustainability. Furthermore, they emphasize the importance of strengthening policies aimed at directing remittances towards sustainable investments, thereby advancing the achievement of the SDGs. Governments are urged to prioritize enhancing regulatory capacities in environmental matters through investments in modern technologies and appropriate standards, aiming to strike a balance between environmental protection and economic needs. Additionally, they should prioritize transparency, public participation, and robust enforcement mechanisms. Encouraging environmentally friendly foreign investments and promoting regional and international cooperation are also crucial steps towards effectively managing local environmental challenges.
