Metropolitan growth has been dramatic in the past several decades, and today metropolitan regions are recognized as the main driving forces in national growth and development as well as in national and global innovation processes. The purpose of this book is to contribute to a better understanding of how metropolitan regions and their subsystems interact and compete, why they differ in their capacity to nurture innovation and growth, and how metropolitan policies must be designed to secure the region's long-term vitality. To that end, it presents new contributions on theories of urban growth, institutions and policies of urban change, and case studies of urban growth prepared by international experts.
