This book is concerned with dynamic relations between urban division of labor, division of consumption and determination of prices structure within a perfectly competitive framework in spatial economy. Our analytical framework examines the issues related to urban dynamics raised in the traditional urban economic theories and provides insights into the issues related to interdependence between knowledge creation and utilization and spatial economies examined by the new urban/regional economic theory. The comparative advantage of our theory is that in providing rich insights into the complex of urban evolution it uses only a few concepts and simplified functional forms and accepts a few assumptions about the behavior of consumers, producers and institutional structures over space.
