Résumé
The Algerian economy is highly dependent with a foreign trade oriented mainly to the export of hydrocarbons. The prospect of depletion of such a non-renewable resource lead economists and leaders to question the future of the economy, the ways and means of diversification. The local products appear as a possible solution because of their importance in the Algerian economy and the specific attachment of Diaspora consumers to these products. Algerian Diaspora is able to impact the process of implementation and export development of these local products to international markets. This cross between diaspora, international trade and local products is the main contribution of this thesis in theoretical terms. This relation is also original in the Algerian and North African context, because there is little research about this. We have defended the thesis that the local products could be one way of diversification of the Algerian foreign trade. In this context, the Diaspora is able to play a significant role both in the development of these products and their introduction in international markets. We supported our demonstration by an original theoretical and methodology approach. Our main results confirm this thesis. However, the institutional and territorial constraints, contradict the involvement of Diaspora networks, slows the process of diversification and enhancement of territories. It this then urgent to implement support and guidance for the benefit of entrepreneurs, territories and local products.
