This collective work examines aspects of urban change around the world. Part 1 describes the global expansion of markets through technology diffusion, decreasing cost and increasing speed of transport and communication, increasing diffusion of information and declining barriers to trade. Part 2 outlines the increasing competition generated among firms and between cities and the impacts on the urban hierarchy including the creation of winners and losers. Part 3 considers the creation of technopoles or technology cities as centres for innovation and development of new technologies and industries. Part 4 analyses changing patterns of living and working at the metropolitan level including dispersal of employment into the suburbs and beyond, and the consequences for commuting patterns, public transport and sustainability of development. Part 5 considers the nature of sustainability of urban systems and of ecosystems for their support and the implications for urban system simulation and planning.
