Benetton, Sun Microsystems and IKEA, successful companies from different industries have common characteristics: These entrepreneurial firms are organized as firm networks and they have been successful despite their lack of resources. To understand their model, inter-organizational activities are the key. Christian Lechner analyzes how inter-firm networks can be a model for competitive advantage. «Competitiveness of Firm Networks» is about a theory of competitive advantage, a theory about the firm and a theory about networks. It explores relevant theories, formulates workable definitions, develops a framework for a strategic network management theory and refines this theory by own original research in the biotechnology and information technology industries. This book - winner of the Lindner price for entrepreneurship research - is written for academics and managers interested in strategic management and entrepreneurship.
