Technology-based firms contribute to dynamic competition, ensure product variety, close market gaps and promote job creation. Their development is impeded by a difficult access to capital, high R&D costs and management deficits. The book analyses their chances and risks in the innovation process. Topics deal with the management of technology-based firms, different aspects on their financing, the spectrum of public promotion programmes and the venture capital market in Germany. Finally, the book centres on regional technology and economic promotion and the creation of regional networks for technology-based firms. The reader documents research of Fraunhofer-ISI on technology-based firms and their environment and aims at a better understanding of specific chances and risks in the development process of such firms.
