We propose here some reflection on the philosophy that guides the implementation of a collaborative knowledge platform on firm and innovation in Region Basse-Normandie (France). Our approach is based on an original mix of the firm and organization theory and social choice theory. The objective is to organize the conditions for a collective production of knowledge in order to contribute to answer the key question : in a context of "agencyfication", how can policy-makers assess and improve effectiveness of innovation policy-implementers set up for the promotion of the Regional Innovation Strategy?
