The triple helix: an evolutionary model of innovations

چکیده
w The ‘‘lock-in’’ model by Arthur Arthur, W.B., 1988. Competing technologies. In: Dosi, G., Freeman, C., Nelson, R., Ž . x Silverberg, G., Soete, L. Eds. , Technical Change and Economic Theory. Pinter, London, pp. 590–607. can be extended to the case of two and even three sources of random variation. Thus, one can model a triple helix of university–industry– government relations. In the case of two sources the stabilization of a technological trajectory is enhanced, while in the case of three a complex regime can be generated. Conditions for lock-in, lock-out, return to equilibrium, substitution, etc., are specified in relation to the assumed complexity of the dynamics under study and with reference to the stage of development, that is, before or after lock-in. Some normative implications of the triple helix model of innovations can be specified. q 2000 Elsevier Science B.V. All rights reserved.

Lifelong , self-directed learning and the maintenance of competence: the triple helix of continuing professional development
Abstract It has been proposed that we think of continuing medical education (CME) as a two-stranded helix, in which one strand represents the internal characteristics of the learner-physician, the other strand the culture and environment in which he or she practices and lives. In many countries, the product of these two strands has been increasingly termed ‘continuing professional development’...
متن کاملThe Triple Helix Model and the Knowledge-Based Economy
The Triple Helix model of university-industry-government relations can be generalized from a neo-institutional model of networks of relations to a neo-evolutionary model of how three selection environments operate upon one another. Two selection mechanisms operating upon each other can mutually shape a trajectory, while three selection environments can be expected to generate a regime. The neo-...

متن کاملOrganizing product innovation: hierarchy, market or triple-helix networks?
This paper assesses the extent to which the organization of the innovation effort in firms, as well as the geographical scale at which this effort is pursued, affects the capacity to benefit from product innovations. Three alternative modes of organization are studied: hierarchy, market and triple-helix-type networks. Furthermore, we consider triple-helix networks at three geographical scales: ...
متن کاملToward Evolutionary Innovation Theory
Abstract: Innovations, commercialized by new or old established firms, located at the core of industrial renewal process. The innovation concept has suffered transformations, along with the evolution of the models that try to explain and understand the innovation process. The innovative process corresponds to all activities that generate technological changes and the dynamic interaction between...
