The dynamics of inter-firm networks in the course of the industry life cycle: The role of appropriability

This paper examines the dynamics of inter-firm networks and introduces a conceptual framework for explaining why inter-firm networks change over time. The framework is based on the idea that patterns of inter-firm linkages are linked to the life cycle development of an industry. Special emphasis is placed on the role of appropriability, i.e. a firm's ability to capture the profits generated by its innovations. the (trans)formation of inter-firm networks in three industries is examined and used to illustrate the relevance of the framework. One important inference from our study is that public policy makers and managers should take into account the phase of industry development before implementing policies to create and/or change inter-firm networks.
