This article studies the networks of intermunicipal cooperation that occur through a process of subnational regionalization. It analyses data from two Regional Communities in the Province of Córdoba, Argentina. The results show that interlocal subjective interdependence and strong relationships between actors, results in greater inter-municipal cooperation Furthermore, the results of the analysis suggest that interpersonal trust does not necessarily result in institutional coordination. While the local political parties are not a significant variable in this study, geographic distance does seem to play a role in the larger process of intergovernmental coordination.
