Book excerpt: Published in 1999. Analyzing and chronicling the continued development of key information, communication and fast transport networks at a global and regional level, this book looks at the transition to an information-based economy, and its urban impacts, at a global, regional and city level. The book outlines the change by defining it as the third great societal transition in the history of human settlement, and points to key factors that have fuelled progress. These include the growth of global telecommunications and fast transport networks; the coming together of information and communication technologies and their links to transport and land use; the shift to information and knowledge as a resource base for new industries; the increasing movement of people and information; the emergence of cities as economic entities, network nodes, and centres for generating, exchanging and processing information, and, most significantly, the competition among cities for these new key elements of of the urban economy.
