globalen und zwischenbetrieblichen Arbeitsteilung gewinnen Innovationskooperationen zwischen Produktions- und Dienstleistungsunternehmen sowie öffentlichen Forschungseinrichtungen immer stärker an Bedeutung. Innerhalb einer Region beeinflußt die Intensität innovativer Verflechtungen...

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...

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 estimated the persistence of knowledge in the inventor networks of nine German regions using alternative assumptions...

Die Studie basiert auf einer empirischen Analyse des Innovationsgeschehens in vier ostdeutschen Fallstudienregionen Dresden, Halle, Jena und Rostock. Alle vier Regionen besitzen sowohl eine universitäre als auch eine industrielle Tradition. Die Entwicklungsverläufe seit dem Systembruch im Jahr...

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...

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...
