From a macro perspective, inventor networks tend to generate remarkably stable structures over time. At the same time, we observe highly dynamic processes at the micro level, in terms of inventor entries and exits as well as formations and terminations of collaborative relationships between...

From a macro perspective, inventor networks are characterized by rather stable structures. However, the high levels of fluidity of inventors and their ties found in reality contradicts this macro pattern. In order to explain these contradicting patterns, we zoom in on the intermediate group...

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...

The paper deals with the significant impact of location on innovation activity that has been found in many empirical studies. Main elements of such an explanation are the specific problems of a division of innovative labor. Based on an outline of these issues the concept of a regional innovation...

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...

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...
