The period of post-socialist transition in Serbia brings more complex actors environment compared to socialistic period, while institutional arrangements are not enough developed to actively involve different groups of actors in spatial policy formulation process. In order to gather certain knowledge as guidelines for redefining institutional practices in Serbia, institutional framework of Serbia was compared in this paper with institutional framework of three developed European countries, especially in relation to the roles of public, private and civil sector in spatial policy formulation process. The European countries selected for the analysis are United Kingdom, Netherlands and Germany because of diverse national administrative traditions, so different institutional arrangements could be researched. By comparing institutional framework in Serbia with the ones in developed European countries following questions are researched: which actors are missing in Serbia, what are the ways institutional arrangements for different groups inclusion into spatial policy formulation process are formed, what are the differences between the roles of certain groups of actors in decision-making process. Current roles of actors in spatial policy formulation process in Serbia are reviewed and possible directions for public, private and civil sector role redefinition in Serbia are discussed in accordance with experiences of developed European countries.
