This special issue of Res Publica about administrative power of municipalities in the Netherlands and Flanders, Belgium, focuses in particular on the meaning of cooperation for the strengthening of administrative power. Until recently discussions on administrative power concentrated mostly on the possibility of the merger of municipalities. The three contributions to this issue demonstrate that different kinds of cooperation are a fair alternative for the strengthening of administrative power of municipalities.

This article examines the impact of the Flemish municipal decree on the administrative power of Flemish municipalities. The general goal of the Flemish municipal decree was the strengthening of administrative power by changing political-political relations, political-administrative relations and the supporting policy and management cycle. This article shows the limited meaning of the political component for this strengthening. Changes in the administrative organization of Flemish municipalities on the other hand are looking more promising, although scale and different types of municipalities continues to stay an important factor.

This article addresses the impact of intermunicipal cooperation on the administrative power of municipalities. It focuses on a specific form of intermunicipal cooperation in the Netherlands, which is called ‘WGRplus’. This concerns the intermunicipal cooperation in the major urban regions in the Netherlands. In this article administrative power is not used as a fixed and quantifiable concept, yet as a process that might contribute to the performance of individual municipalities. It is argued that intermunicipal cooperation strengthens the possibilities of municipalities to address social challenges. The cooperation is considered to be successful and rewarding. It also stimulates the cooperation with relevant social organisations. Yet this form of intermunicipal cooperation has a weak democratic and political profile. Next year the Dutch government will conduct a thorough evaluation of this specific form of intermunicipal cooperation. This is still necessary because the evidence that the administrative power of the municipalities benefits from this specific form of intermunicipal cooperation is not absolutely convincing.

This article examines the relations between local government and the private welfare sector in Flemish municipalities. It argues that because of important transformations in society local governments are dependent on the activities of the private sector to solve social challenges. Within the welfare sector Flemish local governments still have an important role. The question is how municipalities are able to withstand and cope with the power and strength of these private organisations. Maybe the answer lies within professional network management.
