Knowledge, innovative activities and industrial evolution

We argue that the distinction between tacit and codified knowledgeis indeed very important, but it constitutes only a part ofthe categorization of the dimensions of knowledge relevant forunderstanding innovative activities and firms' and industrialevolution. In particular, we emphasize the relevance of thenotion of competencies and of some further properties of knowledge,like technological regimes (opportunities, accessibility andcumulativeness), domains of knowledge (in terms of technology,demand and applications) and knowledge complementarities (andthe related issues of coordination and integration of thesecomplementarities).
