This study investigated how infrastructural development is responding to international tourism and institutional quality in Africa using the system GMM technique and a panel of 31 African economies from 2011 to 2020. Existing studies have generally ignored these relationships. We find that international tourism is an essential driver of infrastructural development in Africa. We also find that the quality of governance institutions significantly promotes infrastructural development in Africa when measured using government effectiveness, rule of law, and regulatory quality, but remain muted when measured using control of corruption, voice and accountability, and political stability. We highlighted the implications of these findings in terms of diversifying the economies of Africa through investments in tourism and reforming the governance institutions in the region to combat corruption, entrench transparent and accountable governance, and promote political stability. Interestingly, our findings further indicate that human capital development, GDP per capita, and remittances are important drivers of infrastructural development in Africa, while the role of foreign direct investment remained significantly negative. We provided policy recommendations based on these findings.
