1 The Evolution of Biotechnology as a Knowledge Industry: Network Movies and Dynamic Analyses of Emergent Structure Walter W. Powell Douglas R. White Kenneth W. Koput Stanford 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 network of contractual collaborations from 1988-99 in relation to both firm-level organizational and financial changes.

2 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

3 1988: Lots of Finance, little R&D

4 1989: Nucleus of R&D attracts more Finance

5 1990: Massive investment in R&D

6 1991: The phase transition is complete

7 1992: …and then it stops

8 1993:

9 1994:

10 1995:

11 1996:

12 1997:

32 Figure G1: Time Series of Growth Parameters: Mean Growth by Tie Activity, Separately for Form of Partners. Left Figure Plots Coefficient of Variation over time for Modal Combinations: Magenta = R&D to Universities and NonProfits, Red = R&D to Government, Green= Finance to Financial, Cyan = Commercial to Biotech, Blue = Commercial to Pharmaceutical and Other For- Profit. Right Figure Plots Coefficient of Variation for all remaining combinations with no color legend.

33 Figure 9: Cycles of Learning and Organizational Returns (Powell et al. 1999) Legend 1. 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).
