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...

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...

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...

Systemic innovation theory emphasizes that innovations are the result of an interdependent exchange process between different organizations. This is reflected in the current paradigm in European innovation policy, which aims at the support of collaborative R&D and innovation projects bringing...

This paper investigates interregional differences in cooperative behavior of manufacturing establishments in the field of research and development (R&D). The empirical analysis for eleven European regions reveals a number of significant differences between these regions in the propensity to...

Literature suggests that location should matter for R&D activities. However, attempts to empirically detect differences in innovation activity between regions have so far been rather unsuccessful. Using a unique data set which contains comparable information about manufacturing enterprises in...
