Abstract : At a time when one questions the need for a new phase of decentralization, this study compares how two regions invest the field of action that constitutes the field of information society. This outlines an innovative and transverse; it does not fit into the prerogatives of a particular level of local community and is marked by the absence of reference other than national or European. The assumption is that ICT can act as an indicator of current trends of decentralization and thus contribute to the debate on the future of regionalization. The work, covering the regions and Midi-Pyrenees Poitou-Charentes, is engaged in two axes. The first is to consider this field of action as an opportunity for the Region to decline a vision for its own development. The second envisages ICT as an opportunity for the Region to test his alleged role in the pivotal role of regional planning. After presenting the general framework of the search and placement of supra-regional institutions vis-à-vis the Information Society, the analysis revealed two regional policies taking into account the growing field, with the denominator common concern to the operational. A model of action described as pragmatic finally settled. His main vehicle is the declination of a comprehensive intervention whose success depends on the effective participation of internal services to the region, but also for a large part, by the sub-regional actors. The goal for the regional institution is to be at the articulation of territorial policies on Information Society and finally as an essential part of its construction.
