What positions and roles do our Nordic cities have in this world of flows, and how does the global network economy impact on Copenhagen, Helsinki, Oslo, and Stockholm, and on Nordic urban policymaking more generally? World cities such as New York, London, Paris and Singapore are seen as central nodes in the global networks of capital, commodities, knowledge, people and cultural symbols. In this sense, they function as important hubs for the interaction of skilled labour and their 'tacit knowledge', as financial control centres and as major points of origin for the generation of different kinds of innovations (i.e. social, cultural, and technical). This Nordregio policy brief highlights how globalisation creates new challenges and opportunities for policymakers in the Nordic capital regions.
