This paper identifies the dimensions of international trade in services that promote export diversification in an unbalanced panel of 48 countries in Sub-Saharan Africa over the period 1996 - 2020. Using the System-Generalized Method of Moments (GMM), the results show that tourism, services total export, export in transport services, travel services, insurances services, financial services, use of licenses services and other business services promote export diversification in SSA. Governments should improve their business environment and strengthen services sector liberalization to attract more foreign direct investments in services. They should also adopt policies and strategies to develop and orient the services sector towards more efficient and high-value-added services.
