Twin cities in the process of metropolisation

Metropolisation is understood here as the process through which a loose collection of proximally located cities starts to become more functionally, culturally and institutionally integrated. It can be assumed that in theory metropolisation enhances performance, and indeed this conviction underlies many European metropolitan development strategies. Yet little is known about how this potential is realised in practice. This paper explores the process of metropolisation in three European 'twin cities': Linköping-Norrköping (Sweden), Rotterdam-The Hague (Netherlands) and Gdansk-Gdynia (Poland). We find preliminary evidence that metropolisation is an upward spiral of integration in which policy-makers play an active role.
