Agricultural production is clearly an important component of West African international trade, especially of its non-extractive exports. And the improved trade performance of the countries is one of the most important pillars of the regional economic integration process. Thus, the purpose here is to identify determinants of West African international trade flows. For this purpose, the expanded Structural Gravity model was used. The overall pattern of international agricultural transactions in this region is dominated by extra-regional transactions and there are differences between intra- and extra-regional determinants. In global transactions, flows are higher among member countries of the Economic Community of West African States (ECOWAS) and the West African Economic and Monetary Union (WAEMU) does not significantly affect those flows. On the other hand, ECOWAS does not have a significant impact on intra-regional agricultural trade and flows are greater among WAEMU member countries. Geographical distance has no significant effect on West African extra-regional international agricultural trade. Commercial agricultural production of the region s countries is focused on extra-regional trade, which is justified by the regional divergence between supply and demand. In order to increase intra-regional international agricultural transactions, expanding regional agroindustrialization is essential to ensure convergence between supply and demand. Acknowledgement :
