The study of the impact of export structure on economic growth in Tunisia offers crucial insights, both theoretical and practical. The first chapter establishes a theoretical foundation by exploring how exports, economic growth and economic diversification are interconnected. Exports are identified as an engine of growth through productivity enhancement, income growth and risk diversification. The second chapter validates these concepts by analyzing empirical data on Tunisia, showing that export diversification strengthens economic resilience and boosts growth. However, the study highlights several limitations, including the difficulty of capturing qualitative nuances and recent exogenous shocks. Future research should deepen these dimensions to better understand the impact of exports on Tunisian economic growth.
