Quick Reference

A system of interconnecting routes which allows movement from one centre to the others. Most networks are made up of nodes (vertices), which are the junctions and terminals, and links (edges) which are the routes or services which connect them. ‘Networks constitute the new social morphology of our societies, and the diffusion of networking logic substantially modifies the operation and outcomes in the processes of production, experience, power and culture’ (M. Castells1996). Dicken (2004) TIBG29, 1 describes situated networks as a generic form of social organization. Brown et al. (2008) GaWC Res. Bul. 236 see the world economy as based upon economic nodes connected as chains/networks. See Glückler (2007) J. Econ. Geog. 7, 5 on economic geography and the evolution of networks.

Network connectivity

is the extent to which movement is possible between points on a network—cities' housing firms with high service values will record large measures of network connectivity. Taylor et al. (2002) esrc attempt to measure the global network connectivity of cities. See also Taylor and Catalano (2001) GaWC Research Paper 61 for global, and banking, network connectivity.
