Density and Strength of Ties in Innovation Networks : A Competence and Governance View

Taking into account both competence and governance issues, and six dimensions of tie strength, this article argues that in networks for exploration there are good reasons, counter to the thesis of the 'strength of weak ties', for a dense structure of ties that are strong in most dimensions.By contrast, in exploitation networks there are good reasons for structures that are non-dense, with ties that are strong in other dimensions than in networks for exploration.
