This important book addresses how long term and large scale shifts from one socio-technical system to another come about, using insights from evolutionary economics, sociology of technology and innovation studies. These major changes involve not just technological changes, but also changes in markets, regulation, culture, industrial networks and infrastructure. The book develops a multi-level perspective, arguing that transitions take place through the alignment of multiple processes at three levels: niche, regime and landscape. This perspective is illustrated by detailed historical case studies: the transition from sailing ships to steamships, the transition from horse-and-carriage to automobiles and the transition from propeller-piston engine aircraft to turbojets. This book will be of great interest to researchers in innovation studies, evolutionary economics, sociology of technology and environmental studies. It will also be useful for policy makers involved in long-term sustainability and systems transitions issues.
