Technological regimes and Schumpeterian patterns of innovation

This paper proposes that the specific pattern of innovative activities in an industry can be explained as the outcome of different technological (learning) regimes. A technological regime is defined by the particular combination of technological opportunities, appropriability of innovations, cumulativeness of technical advances and properties of the knowledge base. Building upon the distinction between Schumpeter Mark I and Schumpeter Mark II industries, this paper provides empirical estimates of the relationships between indicators of the Schumpeterian patterns of innovation (concentration of innovative activities, stability in the hierarchy of innovators and importance of new innovators) and indicators of the variables defining technological regimes
