Abstract: Presently, in France the sets of actors are deeply conditioned by the effects of the decentralisation that took place in 1982, and by the competences transfers. By progressively giving importance to the local levels, the French state gave them the first rank in terms of economical development. Nevertheless, in a very changing overall context, the determinants of the companies' localization, and as a consequence the economical attractiveness of territories, change very quickly. As a result it is essential to obtain tools of territorial intelligence that are able at the same time to describe and anticipate the socioeconomic evolutions and also to link the actors who are in charge of territorial development, from the regional to the infra-regional levels. We would like to present an experiment that is taking place in Franche-Comté with the regional development agency (ARD-FC) and which consists in the structuring of a regional resources platform that is associated to semi independent departmental observatories. We will try to describe what was expected from the regional and infraregional observatory to implement efficient governance, from the project genesis (schedule of conditions and actors consultation) to the philosophy of the conceptual proposals.
