De los modelos de innovación a los regímenes tecnológicos Schumpeterianos

Abstract

The main objetive of this paper is to analyse the Technological Regimes of four European Countries: Spain, Italy, France and the United Kingdom, using data about patents registered in the U.S. Patent and Trademark Office in twenty seven technological fields, during the period 1974-1995. The theoretical bases are the patterns of technological activity outlined by Schumpeter and picked up since theoretical and empirical perspectives by many authors - Nelson y Winter (1982), Winter (1984), Malerba y Orsenigo (1995 y 1996)-. Many questions about the characteristics of technological cumulativeness, appropriability, technological opportunity and the bases of knowledge, are analysed using different indicators about concentration, asymmetry, innovator size and innovative stability and natality.
