This paper analyses the effects of innovation networks on product and pro-cess innovation and sales growth of high technology SMEs. Innovation net-works are positively related to both product and process innovation, i.e. know-ledge creation. One exception is the negative effect of innovation...

We analyze information and knowledge transfer in a sample of 16 German regional innovation networks with almost 300 firms and research organizations involved. The results indicate that strong ties are more beneficial for the exchange of knowledge and information than weak ties. Moreover, our...

A key issue of dfferent streams of economic literature is to determine the impact of certain dimensions of proximity on the cooperative behavior of actors and, thus, on interactive learning processes. This paper is a quantitative study on the impact of technological and geographical proximity on...

The literature on Innovation Systems is divided into several directories. Dif- ferences occur through the definition of the system's borders. This paper intro- duces a methodology how to differentiate between regional and technological effects of cooperative innovation activities and analyzes...

Cooperation can benefit and hurt firms at the same time. An important question then is: when is it better to cooperate. And how can an appropriate partner be selected? In this paper we present a model of inter-firm cooperation driven by cognitive distance, appropriability conditions and external...
