The discussion on regional innovation systems emphasizes the duality of local and global links. While the former enable effective knowledge exchange between regional actors, the latter are considered to provide regional systems with knowledge diverse to their knowledge base. Our empirical...

The development of inventor networks is characterized by the addition of a significant number of new inventors, while a considerable number of incumbent inventors discontinue. We estimate the persistence of knowledge in regional inventor networks using alternative assumptions about knowledge...

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 investigate the stability of cooperative relationships between inventors and consequences for the characteristics and patent productivity of the respective regional innovation systems (RIS). The empirical analysis is for nine German regions over a period of 15 years. We find a rather high...

The positive effect of public research on industrial innovations is beyond controversy: public research institutions produce knowledge that is subsequently transferred into product and process innovations by private businesses. Besides this rather passive role in commercializing inventions,...
