Abstract

We analyse the changing contribution of networks to the innovative performance of 30 pharmaceutical companies from 1989 to 1997. Count data models show that collaborations with universities and biotechnology companies are important determinants of the firms' innovative performance, but their respective contributions diverge when industry matures. Larger firms enjoy a significant size advantage and in-house research activities are highly significant. Returns to scale in research are decreasing over time while the size advantage is increasing. The changing contribution of networks to knowledge production suggests that these are phase-specific, which has substantial managerial and policy implications.
