Patent data for German regions and eleven subsequent years is used to identify collaborative activity as well as the innovative output in each region. The results confirm to some extend previous expectations based on the assumption of an inverted U-relationship. Depending on the regional level of cooperation there are positive and negative effects of a change in regional cooperation behaviour in the industries Radio, Television and Communication Equipment and Machinery and Equipment. No significant results are obtained for the industries Chemicals and Chemical Products as well as Medical, Precision and Optical Instruments. jportal_jpjournal_00000016 2011-10-14T06:25:54.583Z 2011-10-14T06:24:53.364Z
