Multiscalar governance and institutional change: critical junctures in European spatial planning.

Change of major social institutions sometimes takes place during relatively compressed periods in which previously relatively stable institutions are transformed. Historical institutionalism and comparative historical analysis refer to these turning points as critical junctures, and have developed a valuable set of conceptual frames and research methods for their systematic and comparative study. A core idea of the critical junctures approach is that periods of significant institutional change often result in distinct outcomes in different cases, and sometimes produce enduring consequences in the form of subsequent pathways of institutional development. If this is so, then careful analysis of the dynamics of such change processes, the factors that enable change and those that shape outcomes in each case are important projects for planning history. This essay draws on recent research on permissive and productive conditions of institutional change, the fractal-like quality of multi-scalar institutional change, comparative sequential analysis, process-tracing, and counterfactual analysis in developing an analysis of the broader significance of the European spatial planning policies examined in the papers included in this special issue. A final section considers some of the distinctive characteristics of critical junctures at urban and regional scales compared to those at national or transnational scales in the light of these cases.
