Utilising an original and innovative approach called ‘social constructivist fusion perspective’, the author addresses Europeanization across several key factors. The author assesses the influence of the EU on ‘half-way member countries’, and the impact of identity politics and domestic structures, which factors contribute to or hinder Europeanization, and attempts to empirically measure Europeanization at the actor level. It analyses the impact of domestic and European structures on the identities, interests, attitudes and foreign policy practices of the Norwegian policy-makers.
