ABSTRACT:The observation of economic activity grants an equally important place to learning as some recent theoretical problems. However, what is meant by learning, and what in the productive activity enables the application of the learning process? This paper examines the notion of learning, as far as the firm is concerned, putting the emphasis on two main directions. On one hand, learning is not only a dynamic but also a process: it is not only a matter of going from one point to another, but also a process of construction of knowledge and rules. On the other hand, this process must be understood as an articulation between individual and organizational learning.
