Transversality and Transition: Green Innovation and New Regional Path Creation

Since Paul David first published his economic histories of path-dependent innovation, the subject has exerted fascination upon scholars of innovation and technological change and, latterly, regional scientists and economic geographers. This paper speaks of the third and fourth of these communities in the main, though it may have theoretical and empirical elements of interest to the first two as well. It begins with an overview of recent perspectives and critiques concerning the relevance of the path dependence concept to the understanding of regional economic development and its associated governance. It then goes on to discuss the contribution of evolutionary economic geography to thinking about "branching" from path dependence and the creation of new paths. Evidence for key generic spatial processes of path transition is provided before the main content of the paper concludes with new insights into the contributions of regional innovation policy to path evolution. Conclusions are then drawn.
