Schumpeterian perspectives on industrial change suggest a relationship
between new firms and the regionally specific technological bases for
innovation. However, the links between such firms and the knowledge b
ases for innovation are more implicit than explicit. The innovation pr
ocess in new firms reflects both the capabilities found within the fir
m as well as information sourcing from without. This paper seeks to ar
ticulate the nature of change in relationships between firms in scienc
e-based industries and the technological infrastructure accessed to su
pport innovation, as such industries mature out of the birth phase. In
novation is treated as decision making, identifying the firm as innova
tor and agent of change. Survey research suggests that a shift in the
sourcing of information, and an associated shift in the character of i
nformation accessed, occurred with maturation in the study industry, c
omprised of biotechnology finns in the U.S. ''Early'' and ''later'' fo
rming firms show somewhat different technology sourcing patterns. Inte
rviews were conducted to help interpret these findings. Implications f
or industry development are suggested.
