Actors, Institutions and Innovation Processes in New Path Creation : The Regional Emergence and Evolution of Wind Energy Technology in Germany

Abstract

The recent literature of evolutionary economic geography points out that new technologies do not emerge randomly across space. The evolution of the economic landscape is associated with processes of path creation, regional branching and regional path dependence. However, the underlying processes and the role of the actors are under-investigated and poorly understood. This research gap is the starting point of this dissertation. The thesis focuses on the actors, mechanisms and processes of path creation and the co-evolution of technology and institutions. The overall aim of the dissertation is to provide theoretical foundation and empirical evidence to understand and explain the regional emergence and evolution of new technologies. The key question of the thesis is: Where, how, by whom and under which conditions do new technologies emerge. Based on research in evolutionary economic geography, institutional economic geography, and social and organizational science, a revised theoretical and conceptual framework is developed for analyzing and explaining the regional emergence and evolution of new technologies. The framework provides an actor-centered, dynamic perspective and goes beyond technological diversification and regional branching processes. Hence, the dissertation contributes to the current theoretical debate on path creation and the role of institutions and institutional change for the evolution of new technologies. The empirical analysis is based on an explanatory case study on the emergence and evolution of the onshore wind energy technology in Germany. A qualitative content analysis was employed. Data were collected by a document analysis and 40 in-depth interviews with relevant stakeholders. The findings show that besides energy and environmental policies at the national level, path creation was strongly influenced by the regional institutional environment. The findings also give qualitative insights into different types of actors and their motives and activities in an emerging technology. Concerning the mechanisms, the thesis identifies entrepreneurial activities and regional industry diversification as the key mechanisms in new regional path creation. These were later strengthened by various exogenous impulses. The relevance of the processes differs between regions. The thesis also reveals interrelations and feedback mechanisms between technological development and the institutional environment and finds that the co-evolution of supporting institutions like technical standards, the Electricity Feed-in Act and the Renewable Energy Sources Act was a key success factor for the evolution of wind energy technology. It was found that co-evolution was driven by actors who shaped and changed their institutional environment.
