This study explores the complex relationship between migration and intellectual capital, focusing on the mediating roles of digitalization and institutional quality. Guided by human capital theory, the research aims to uncover how the movement of people across regions contributes to knowledge transfer, innovation, and human resource development within Sub-Saharan Africa. The study is particularly relevant as migration patterns increasingly influence economic growth and the diffusion of digital technologies in developing economies.
The empirical model was developed using data from 47 Sub-Saharan African regions, comprising 18 South-Central and 29 West-East regions, with a total of 1,081 observations covering the period from 2000 to 2022. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), the study examined the direct and indirect relationships among migration, digitalization, institutional quality, and intellectual capital. This approach enabled a comprehensive understanding of how digital and institutional factors mediate the benefits of migration across diverse regional contexts.
The findings indicate that in South-Central Africa, migration exerts a significant and positive influence on intellectual capital, digitalization, and institutional quality. Migrant flows in these regions appear to enhance knowledge exchange, encourage technology adoption, and strengthen governance systems. Conversely, in the West-East regions, the direct relationship between migration and intellectual capital was not significant. However, migration demonstrated a positive and substantial effect on digitalization and institutional quality, which in turn contributed indirectly to intellectual capital development.
When the entire sample was analyzed, the results confirmed that migration positively impacts digitalization, institutional quality, and intellectual capital across Sub-Saharan Africa. Both digitalization and institutional quality were found to play significant mediating roles, suggesting that migration enhances intellectual capital more effectively in regions with stronger digital infrastructures and better governance. This underscores the importance of fostering digital transformation and institutional reforms to maximize the intellectual benefits of migration.
Further insights from multigroup analysis revealed notable regional differences. The impact of migration on digitalization, institutional quality, and intellectual capital was higher in the South-Central regions compared to the West-East regions. Interestingly, the mediating effects of digitalization and institutional quality were found to be stronger in the West-East regions, suggesting that these factors can help offset the weaker direct relationship between migration and intellectual capital.
Overall, this study provides valuable policy implications for governments and development agencies in Sub-Saharan Africa. Strengthening digital ecosystems and improving institutional frameworks can enhance the intellectual and economic dividends of migration. By integrating digital transformation strategies with institutional reforms, countries can better leverage migration as a driver of innovation, education, and sustainable development, aligning closely with the objectives of the United Nations Sustainable Development Goals (SDGs).
