Innovation and innovators inhabit an institutional space, which is partially defined by formal positions and partially by informal networks. This article investigates the role of politicians and bureaucrats in fostering innovation inside government and provides an empirical explanation of who the innovators are, whether this is mostly an attribute of position or role, or mostly an effect of certain forms of networking. The study uses original data collected from 11 municipal governments in Australia in order to define and describe the normative underpinnings of innovation inside government and to show the importance of advice and strategic information networks among politicians and senior bureaucrats (nā=ā947). Social network analysis is combined with conventional statistical analysis in order to demonstrate the comparative importance of networks in explaining who innovates.
