Abstract Research on policy network formation has contributed to an understanding of the patterns of interaction among political actors. Belief homophily, power seeking, and opportunity structures provide explanations studied for specific policy areas. This study tests these established theories in a different environment by asking: What drives policy network formation at the local level? From a review of the literature on policy networks and local politics, the study derives nine hypotheses, which are tested for a German municipality. Information and coordination networks have been collected among its councilors through an online survey. The study identifies the drivers of their formation utilizing exponential random graph models. Findings support the effects of party membership and perceived influence. They also point to the tendency of councilors to coordinate with the mayor and they emphasize local councils as an influential opportunity structure specific to local networks.
