We explore the temporal evolution of cities and firms (i.e. both modes) in a two-mode intercity corporate network formed by 50 leading advanced producer service firms across 154 cities for the years 2000 and 2010. Drawing upon one-mode network projection and three network centralities, we assess...

Using the concept of world city formation to identify 53 European cities, a typology is produced through a principal components analysis of the locations of 46 global firms providing advanced producer services. The typology is based on grouping cities in terms of similar mixes of service firms....

This paper aims to contribute to the literature on the rise of so-called 'network cities' through an empirical analysis of hubs in the global airline network. Standard airline databases do not feature the actual routes flown by passengers, and therefore, a new and previously untapped database is...

This paper aims to refine existing approaches for classifying nodes in spatial networks. Apart from generally used variables measuring (i) the total connectivity of a node and (ii) the spatial make-up of this total connectivity, we argue that a third indicator should be taken into account when...

<b>The notion that there is a European 'system of cities' or 'urban hierarchy' has been an attractive idea, since it appears to provide a coherent subset of cities to study within a regional context. Under conditions of contemporary globalisation, however, the spatial order of European cities can...</b>

The paper begins with an introduction into the interlocking network model (INM) initially specified by Peter Taylor in the context of the Globalization and World Cities (GaWC) research network. For that purpose, the intellectual background, purpose, key principles and subsequent applications of...
