Locating cities on global circuits

This paper discusses the cities that have the resources which enable firms and markets to be global. It considers the new intensity and complexity of globally-connected systems of production, finance and management which may disperse production, yet need (relatively few) networks of cities to provide their organizational and management architecture. This produces new geographies and hierarchies of centrality - particular cities and regions that have key roles in globalization. Many such cities become far more closely linked to the global economy than to their regional or national economies - and this can have harsh consequences locally, pushing out firms and people that are not within the internationalized sector. The paper discusses why certain cities retain such importance, when production is so dispersed and when telecommunications and rapid transport systems have limited the advantages of spatial concentration. It also considers the dependence of global cities on each other; a crisis in one key centre often brings problems rather than opportunities for others.
