We investigate the regional emergence of new information technology start-ups in Germany. The largest share of these start-ups is located in cities or densely populated regions that are well equipped with institutions of higher education and research. The empirical analysis clearly indicates the...

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...

The value of social network analysis is critically dependent on the comprehensive and reliable identification of actors and their relationships. We compare regional knowledge networks based on different types of data sources, namely, co-patents, co-publications, and publicly subsidized...

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...
