The Evolution of Biotechnology as a Knowledge Industry: Network Movies and Dynamic Analyses of Emergent Structure • Walter W. Powell Douglas R. White Kenneth W. KoputStanford University UC Irvine University of Arizona Slides by Douglas R. White • Biotechnology as a knowledge-based industry involves extensive reliance on organizational learning. This occurs through networks of dense collaborative ties among organizations. We model the emergence of the industry networkof contractual collaborations from 1988-99 in relation to both firm-level organizational and financial changes.
Network Movie: 1988-99 • The following twelve slides show the evolution of collaborative contracts within the biotech industry • Green ties =Finance • Red ties =Res&Dev • Grey =Finance • LiteBlue =Biotech • Yellow =Pharmaceuticals • Orange =Res.Labs and Universities • DarkBrown =Government (e.g., NIH) • Pink =Miscellaneous
1988: Lots of Finance, little R&D
1989: Nucleus of R&D attracts more Finance
1990: Massive investment in R&D
1991: The phase transition is complete
1992: …and then it stops

Ovals represent network properties, rectangles are performance and outcome measures, while rounded rectangles can be treated as either firm characteristics or outcomes.2. Shadowed components carry over from Powell et al. (1996).
