Introduction

Global city-thinking has, in the past years, had a very real pull on society. Global cities seem an unavoidable fact of everyday world affairs. This volume gathers a forum that integrates the extensive set of disciplinary dimensions to which the interdisciplinary concept of the global city can help to tackle the policy challenges of today's metropolises. Its chapters are drawn from viewpoints including the cultural, economic, historical, postcolonial, virtual, architectural, literary, security and political dimensions of global cities. Tasked with providing a rejoinder to the global city scholarship from each of these perspectives, the authors illustrate what twin analytical and practical challenges emerge from juxtaposing these stances to the concept of the 'global city'. They rely not solely on theory but also on sample case studies either drawn from long-lived global cities such as New York, Shanghai and London, or emerging metropolises like Dubai, Cape Town and Sydney.
