We analyze the evolution of the international collaboration network in photovoltaic research. Using data on scientific … publications for the period 1980-2015, we apply social network analysis to trace the evolution of the global network of countries … steady increase of publications and collaboration within the global research network.

The objective is to estimate how region-internal and region-external factors influence network embeddedness … in the distinct network types, in order to identify differences in their driving factors at the regional level. In our …

The success breeds success hypothesis has been mainly applied to theoretical network approaches. We investigate the … network, its topological architecture, the individual actors that make up the network, and through a comparison of the Airbus … structure is mirrored in the architecture of the European aerospace R&D collaboration network, where well-connected hub …

both, the network of R&D collaborations as well as the market structure, are endogenously determined. We show that the … coevolution of market and network structure matter for the relationship between competition and innovation. Moreover, our model … allows us to explain differences in the R&D network structures observed across different industries, and how they are related …
