Abstract EN:

This work enlighten regional leader about the possibility to put the "territoire en mouvement" when these one are collectively subject to self-organization forces. We use an analytical framework based on social networks dynamic and individual situated rationality. We draw two main conclusions. Optimal spatial matching is a crucial function of the composition of social networks (diversity). A social position at the interface of the information sources (a social frontier) gives the attribute od a critical agent. This one can stimulate collective spatial dynamic. These results lay the foundations of a new leverage for regional leader. Since, the position of a territory inside rank-size hierarchy determines its attractivity, i. E. An ex ante diffusion od site's characteristics, dynamic location rely on social networks especially as territory is peripherical. Finally, we formulate recommandations for a situates regional politic based on a mix of financial as well as informational incentives.
