Implementing strategic spatial plans is a complex task. The process involves strategy formation, institutional capacity building, funding mechanism establishment and governance arrangements, which take shape within complex power configurations. Based on empirical evidence gathered by interviewing regional planning experts, this paper focuses on the role of governance arrangements and funding mechanisms in current practices of strategic plan implementation in 14 European urban regions. This investigation was completed bearing in mind power configurations, which shape and frame governance arrangements and funding mechanism in planning practice. A cross-case comparison provides evidence that, among the governance arrangements influencing plan implementation, negotiation and interest groups involvement are pivotal. Negotiation involves private interest groups, such as real estate agencies and environmental non-governmental organizations. The paper shows that in some case studies private interest groups have a substantial bargaining power to negotiate, for example, the development of a new housing settlement or a retail facility, while other groups struggle to safeguard natural areas. It is also during negotiations that plan implementation intentions are prioritized, strategic urban projects are formulated and funding mechanisms are established. The paper demonstrates that to truly grasp plan implementation praxis it is necessary to go beyond multi-actor involvement and inter-scalar government cooperation. It is necessary to scrutinize the funding sources, investigate who wins and who loses while negotiations are happening, and how plan implementation decisions are actually made.
