Abstract: 
This work deals with the determinants of cooperative invention and innovation within innovation systems. Several proximity dimensions are used to identify the levels on which systemic innovation activities can be observed. To disentangle the effects of different proximity dimensions a procedure is suggested to identify the relative regional impact (RRI) on cooperative invention and innovation. Applying this method to German patent data shows that there are significant differences in the RRI of German regions. These differences are related to measures of the technological relatedness of the regions knowledge bases, and over time they show a considerable path dependency.
