Institutionalizing EU strategic spatial planning into domestic planning systems: trajectories of change in Italy and England

This paper proposes approaching the emergence and evolution of the Europeanisation of national planning using conceptual frameworks from historical institutionalism in order to shed light on the mechanisms and trajectories of domestic change arising from the influence of EU strategic planning. It seeks in particular to examine Europeanisation in terms of the extent to which EU spatial planning has become a driving force for institutional changes in very different national planning systems. Returning to the changes that occurred in the Italian and English planning systems in the last two decades, the author provides insight into the attempts to insert and transpose EU spatial planning concepts and instruments into domestic systems, dealing with path dependency and European influence. By reading these processes from a historical institutionalist perspective, the paper aims to enhance understanding of the relative influence of European spatial planning on national planning systems, identifying mechanisms and trajectories of domestic change in different planning systems. Key findings concern the diverse modes and degree of institutionalisation of EU strategic spatial planning, examining tendencies to replace the status quo through displacements in England and to progress through a path-dependent trajectory in Italy.
