The dominant focus in the literature until now has been on how networks enable and constrain action, whereas the question what factors enable and constrain networks has been largely ignored. To fill this void, this paper aims to develop all understanding of the role of ex ante factors and processes that influence network evolution. Empirically, we study network evolution in the biotechnology industry along two levels of analysis: network and dyad level. One of the key findings is that these two levels seem to change relatedly in response to exogenous environmental change and that network evolution, within a changing context of technological innovation, seems to be Supportive of the idea of a path from weak ties and non-density in the early phase towards strong(er) ties and increasing density in later phases. More generally, our framework contributes by elucidating not only how networks evolve but also why they evolve in ways they do.
