1 SASKIA SASSEN <strong>An</strong> <strong>exploration</strong> <strong>of</strong> <strong>the</strong> new economic role <strong>of</strong> cities and <strong>the</strong> networks <strong>the</strong>y form <strong>in</strong> an <strong>in</strong>creas<strong>in</strong>gly globalised world 20 21
SINCE THE EARLY 1980S THERE HAVE BEEN DRAMATIC CHANGES IN THE STRUCTURE OF THE BUSINESS AND FINANCIAL SECTORS, AND A SHARP ASCENDANCE OF A CULTURAL SECTOR As recently as <strong>the</strong> 1970s, many <strong>of</strong> our great cities were <strong>in</strong> physical decay and los<strong>in</strong>g people, firms, key roles <strong>in</strong> <strong>the</strong> national economy, and <strong>the</strong>ir share <strong>of</strong> national wealth. As we move <strong>in</strong>to <strong>the</strong> 21st century, a rapidly grow<strong>in</strong>g number <strong>of</strong> cities have re–emerged as strategic places for a wide range <strong>of</strong> activities and dynamics. Even though major cities worldwide have long been centres for bus<strong>in</strong>ess and bank<strong>in</strong>g, s<strong>in</strong>ce <strong>the</strong> early 1980s <strong>the</strong>re have been dramatic changes <strong>in</strong> <strong>the</strong> structure <strong>of</strong> <strong>the</strong> bus<strong>in</strong>ess and f<strong>in</strong>ancial sectors, and a sharp ascendance <strong>of</strong> a cultural sector. Fur<strong>the</strong>r, <strong>the</strong> number <strong>of</strong> global cities has grown sharply as globalisation expanded. Critical, and partly underly<strong>in</strong>g all <strong>the</strong> o<strong>the</strong>r dimensions, is <strong>the</strong> new economic role <strong>of</strong> cities <strong>in</strong> an <strong>in</strong>creas<strong>in</strong>gly globalised world, and <strong>the</strong> associated architectural and technical revolutions. The network <strong>of</strong> about 50 global cities <strong>in</strong> <strong>the</strong> world today provides <strong>the</strong> organisational format for cross–border flows. A key feature <strong>of</strong> this format is that it conta<strong>in</strong>s both <strong>the</strong> capabilities for organis<strong>in</strong>g enormous geographic dispersal <strong>of</strong> firms and jobs on <strong>the</strong> one hand, and <strong>the</strong> capabilities for ma<strong>in</strong>ta<strong>in</strong><strong>in</strong>g centralised control over that dispersal. The management and servic<strong>in</strong>g <strong>of</strong> much <strong>of</strong> <strong>the</strong> global economic system takes place <strong>in</strong> this grow<strong>in</strong>g network <strong>of</strong> global cities and regions. This role <strong>in</strong>volves only certa<strong>in</strong> components <strong>of</strong> urban economies, but it has contributed to a reposition<strong>in</strong>g <strong>of</strong> cities both nationally and globally. The implantation <strong>of</strong> global processes and markets has had massive consequences for <strong>the</strong> restructur<strong>in</strong>g <strong>of</strong> large stretches <strong>of</strong> urban space. While this mix <strong>of</strong> activities is part <strong>of</strong> a new urban economy that is most pronounced <strong>in</strong> global cities, it is also emerg<strong>in</strong>g <strong>in</strong> smaller and less globalised cities. This new urban services–centred core has mostly replaced <strong>the</strong> older, typically more manufactur<strong>in</strong>g oriented core <strong>of</strong> service and production activities. Some <strong>of</strong> <strong>the</strong>se cities serve regional or subnational markets. Regionally and nationally oriented firms need not negotiate <strong>the</strong> complexities <strong>of</strong> <strong>in</strong>ternational borders and <strong>the</strong> regulations <strong>of</strong> different countries, but <strong>the</strong>y are still faced with a regionally dispersed network <strong>of</strong> operations that requires centralised control and servic<strong>in</strong>g, and <strong>the</strong> full range <strong>of</strong> corporate bus<strong>in</strong>ess services— <strong>in</strong>surance, legal, account<strong>in</strong>g, advertis<strong>in</strong>g and o<strong>the</strong>r such services. Thus <strong>the</strong>se cities have also seen an <strong>in</strong>crease <strong>in</strong> high–<strong>in</strong>come pr<strong>of</strong>essional jobs and <strong>the</strong>reby growth <strong>in</strong> sectors l<strong>in</strong>ked to quality <strong>of</strong> life, <strong>in</strong>clud<strong>in</strong>g <strong>the</strong> cultural sector. <strong>An</strong>d, like global cities, <strong>the</strong>y have also seen a growth <strong>in</strong> economic and spatial <strong>in</strong>equalities. Thus, <strong>the</strong> specific difference that globalisation makes to <strong>the</strong> grow<strong>in</strong>g service–<strong>in</strong>tensity <strong>in</strong> <strong>the</strong> organisation <strong>of</strong> <strong>the</strong> economy is to raise <strong>the</strong> scale and <strong>the</strong> complexity <strong>of</strong> transactions and <strong>the</strong> orders <strong>of</strong> magnitude <strong>of</strong> pr<strong>of</strong>its and <strong>in</strong>comes. Although many <strong>of</strong> <strong>the</strong>se changes are by now familiar, it is far less clear why cities should matter more today <strong>in</strong> a globalised world than <strong>the</strong>y did <strong>in</strong> <strong>the</strong> Keynesian world <strong>of</strong> <strong>the</strong> mid– 1900s. In contrast, much is known about <strong>the</strong> wealth and power <strong>of</strong> today’s global firms and global f<strong>in</strong>ancial exchanges. Their ascendance <strong>in</strong> a globalis<strong>in</strong>g world is not surpris<strong>in</strong>g. <strong>An</strong>d <strong>the</strong> new <strong>in</strong>formation and communication technologies are typically seen as <strong>the</strong> handmaiden <strong>of</strong> <strong>the</strong>se firms and exchanges—both tool and <strong>in</strong>frastructure. What <strong>the</strong>n are <strong>the</strong> orig<strong>in</strong>s and <strong>the</strong> explanation <strong>of</strong> this urban transformation? 1.
