This paper deals with the effects of publicly funded research at universiti
es, polytechnics and federal research laboratories on industrial innovation
s in Germany. We discuss the characteristics of companies that benefit from
the findings of public research institutions. In questioning 2300 companie
s, we found that less than one-tenth of product- or process-innovating firm
s introduced innovations between 1993 and 1995 that would not have been dev
eloped without public research. These new products amount to approximately
5% of all new product sales. Universities are cited by firms with publicly
supported innovations as the most important source, although publicly finan
ced laboratories get almost as many citations. Big science laboratories are
almost invisible, suggesting that their technology transfer to industrial
firms still lacks effectiveness. Firms also tend to cite research instituti
ons that are located close to the firm. But contrary to the widely held opi
nion that proximity to public research institutions does promote collaborat
ion between firms and public research and increase the amount of received k
nowledge spillovers, we found no higher probability of publicly supported i
nnovations for firms in Germany that an located near universities or polyte
chnics. However, the firm's own R&D activities instead support the ability
to absorb the fndings of public research and turn them into innovations. Ad
ditionally, firms with high R&D intensities cite remote public research ins
titutes more frequently than less R&D-intensive firms, suggesting that in G
ermany, high-technology does not depend on co-location of public and privat
e research. (C) 1999 Elsevier Science B.V. All rights reserved.
