Exploring five key dimensions—geographical, cognitive, institutional, organizational, and social—it shows how the most effective combinations of these dimensions support strong, sustainability-oriented innovation networks. Through an analysis of how these dimensions interact, the book identifies common patterns in successful collaborations. It provides practical guidance for companies, policymakers, universities, and civil society organizations designing innovation networks or selecting partners for collaborative projects. Policy actors will find guidance for crafting strategies that promote sustainability more effectively. At its core, the book introduces a refined analytical framework for studying multiactor settings, which are typical of sustainable innovation. It addresses the complexity of sustainability challenges and the dispersed, context-specific knowledge they require. Drawing on innovation systems research and sustainability science, the book provides a deeper understanding of how sustainable innovations take shape and thrive.
