Previous research has shown that the comprehensive-integrative planning model seems to be expedient for modernising planning systems, specifically regarding the relation between spatial planning and sectoral policies. However, contemporary, and particularly comparable studies are non-existent. Based on empirical findings from a European research project our comparative analysis explores whether spatial planning in nine countries conforms to key features of this idealised planning model. Our analysis reveals discrepancies regarding how spatial planning is positioned in relation to sectoral policies across the various countries. We argue that this planning model appears rather to be in a state of dissolution than of consolidation.
