Technological regimes and Schumpeterian patterns of innovation

This paper proposes that the specific pattern of innovative activities in a n industry can be explained as the outcome of different technological (lear ning) regimes. A technological regime is defined by the particular combinat ion of technological opportunities, appropriability of innovations, cumulat iveness of technical advances and properties of the knowledge base. Buildin g upon the distinction between Schumpeter Mark I and Schumpeter Mark II ind ustries, this paper provides empirical estimates of the relationships betwe en indicators of the Schumpeterian patterns of innovation (concentration of innovative activities, stability in the hierarchy of innovators and import ance of new innovators) and indicators of the variables defining technologi cal regimes.
