L'expansion fonctionnelle, nouvelle mesure de l'innovation. Analyse empirique et modélisation post-lancastérienne de la transformation des biens de consommation

Abstract : The analysis of the phenomenon of consumer goods transformation based on the functional expansion of these goods over time, has mobilized and challenged various theoretical approaches, whether in management science, evolutionary economics or engineering design.This thesis proposes to assess the functional expansion of consumer goods, to understand whether the transformation of consumer goods is rare or rather permanent over time. Using a new measuring tool, first, we could reject the lancasterian hypothesis of stability of consumer goods over time, by showing that the transformation of consumer goods is permanent and that new functions emerge constantly over time. Then we have shown that the emergence of innovations is non-poissonian emergence and controlled, that it is not exclusively the result of an external shock from the design, but that innovation can tip regardless of market needs or new technologies, through innovative design efforts.Finally, the thesis examines the role of consumerist prescription in maintaining market dynamics over time. This dynamic requires the continuous learning of functional expansion by consumers. So we show how and why the prescription facilitates the learning process, which in turn ensures a permanent transformation of consumer goods, and implies a continuous dynamic between supply and demand.
