The rescaling of state emphasizes the rise of the regional and the city-regional scale in particular, as a new unit for policy making. The new governing strategy is referred to as regional governance, were both governmental and / or nongovernmental entities work together for the purpose of joint policy making or service delivery. This paper focuses on the operationalization of regional governance and links those findings to the actual debates surrounding the institutional organization of Flanders. A quantitative analysis of regional arrangements in Flanders and in the area of Mid-West Flanders, helps to clarify the nature of the rescaling of the state: the rescaling is the result of bottom – up and top – down initiatives and covers as well joined government arrangements as collaborative governance arrangements integrating public and private organizations. Further, we notice different roles of the Flemish government, as she is present at the regional level both as a meta-governor, actor and financier. By showing the nature and the content of regional governance, this paper helps to clarify the political debate that is going on now in Flanders. A debate dominated by classical institutional discussions and related to the issue of institutional fuzziness, efficiency and accountability. It is argued however that the political discussion and the organization of the public sector in Flanders should be renewed and should be inspired by this relatively new phenomenon. The rescaling of the regional state should be understood by using concepts, theories and instruments inspired by the literature on networks and collaborative governance.
