We analyze the characteristics of new businesses in the German ICT industry, distinguishing them based on their choice between two IPR regimes: open source software (OSS) or closed source software (CSS). The share of new firms with an OSS-based business model has increased considerably over the...

The emergence and solidification of network patterns is typically explained by the preferential attachment rule. The underlying logic is that a small number of actors which are characterized by an above average degree attract links at a higher rate than others. We raise the question as to what...

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...

We describe and compare the development trajectories of two German regions, South Saxony and Mecklenburg, with a special focus on entrepreneurship and innovation. South Saxony has a long history of self-employment and knowledge generation that results in a persistent culture of innovative...

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...

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...

Systemic innovation theory emphasizes that innovations are the result of an interdependent exchange process between different organizations. This is reflected in the current paradigm in European innovation policy, which aims at the support of collaborative R&D and innovation projects bringing...
