This article has been divided into three parts, The First part studies the concept of a (NIS). Then the second part analyzes the reality of innovation in Algeria, This analysis will allow the third part which is proposing a model of national innovation system specific to Algeria. We use the descriptive and historical approach in the theoretical aspect and we use the analytical approach to the case of Algeria and in finally we propose a model for a (NIS) in Algeria. The most important results that have been reached is that the level of innovation in Algeria is still far from the international level in both the input and output elements of innovation, and the efforts made to develop innovation have not yet been able to create an ecosystem that encourages innovation. Therefore, it has become necessary to move towards building a national innovation system.ennational ; innovation ; system ; model ; AlgeriaArticle
