Innovation networks are a major source for acquiring new information and knowledge and thus for supporting innovation processes. Despite the many theoretical and empirical contributions to the explanation of networks, many questions still remain open. For example: How can networks, if they do not emerge by their own, be initiated? How can fragmentation in innovation systems be overcome? And how can networking experience from market economies be transferred to the emerging economies of Central and Eastern Europe? By presenting a selection of papers which address innovation networking from theoretical and political viewpoints, the book aims at giving answers to these questions.
