Cross-border policy networks in the Basel region: the effect of national borders and brokerage roles.

This paper provides evidence of how national borders affect the structure of policy networks. Our analysis of the Basel cross-border metropolitan region located across Switzerland, France and Germany considers the case of public transportation in border regions. Using a social network analysis of the relationships between 44 actors, we show that national borders play a diminishing role in the formation of policy networks for both information exchange and decision making. Local actors develop different brokerage roles according to their country of origin: Swiss actors function as coordinator and representative brokers vis-à-vis actors located in France and Germany.
