This book explores the relationship between space and economy, the spatial expressions of the knowledge economy. The capitalist industrial economy produced its own space, which differed radically from its predecessor agrarian and mercantile economies. If a new knowledge-based economy is emerging, it is similarly expected to produce its own space to suit the new circumstances of production and consumption. If these spatial expressions do exist, even if in incomplete and partial forms, they are likely to be the model for the future of cities.
