  Productive capacity has emerged as a critical indicator of long-term economic development, particularly for regions undergoing rapid structural transformation, such as Sub-Saharan Africa (SSA). Despite increasing global interest, the key drivers of productive capacity in SSA remain insufficiently explored, especially within the context of tourism and migration. Existing studies predominantly rely on GDP-based growth models and often examine tourism and migration separately, overlooking their combined influence on structural development. Moreover, the role of institutional quality in shaping productive capacity is under-investigated. This study examines how international tourism and migration affect productive capacity growth in SSA, while also considering the contributions of urbanization, trade openness, and institutional quality. Using panel data from 38 SSA countries between 2011 and 2021, the analysis employs a dynamic System Generalized Method of Moments (System GMM) estimator to address endogeneity, unobserved heterogeneity, and simultaneity among variables. The results indicate that international tourism and migration exert positive and statistically significant effects on productive capacity. Institutional quality emerges as the most influential driver, followed by urbanization and trade openness. These findings underscore the importance of structural and governance-related factors in enhancing the region’s productive capacity. Tourism and migration contribute meaningfully to productive capacity growth; however, their impact is substantially conditioned by the quality of governance and structural enablers. Policymakers should adopt sustainable tourism strategies, strengthen security and infrastructure, develop migration-friendly frameworks, enhance human capital, and prioritize institutional reforms to maximize long-term productive capacity in SSA.

  Africa continues to face persistent development challenges, including poverty, income inequality, limited access to healthcare services, and disparities in education. These challenges contradict the objectives of the Sustainable Development Goals (SDGs), which emphasize the importance of innovation, infrastructure development, and strong institutions. Technological innovation has increasingly been recognized as a key channel for promoting infrastructure development, improving economic complexity, and strengthening institutional performance. Motivated by these considerations, this study examines the combined effects of technological innovation, governance institutions, human capital development, infrastructure, and foreign direct investment on economic complexity in Africa. In addition, the study investigates how technological innovation, governance institutions, remittances, foreign direct investment, and economic complexity influence infrastructure development across African economies. The analysis employs the system generalized method of moments (system GMM) estimator using panel data for 31 African countries covering the period from 2011 to 2020. The results reveal that technological innovation has a positive and statistically significant effect on both economic complexity and infrastructure development in Africa. However, the indicators of governance institutions are largely negative and statistically insignificant in their influence on economic complexity and infrastructure. Furthermore, governance institutions do not significantly moderate the relationship between technological innovation and these development outcomes. These findings highlight the importance of strengthening technological innovation systems while addressing institutional weaknesses to promote sustainable economic development across the African continent.
