Bridging technologies in the regional knowledge space: measurement and evolution

Bridging Technologies connect otherwise unrelated fields in regional knowledge spaces. By establishing new connections between technologies, they enable technological development through processes of recombinant innovation. In this paper, we develop a set of indicators that help us to characterise technologies in terms of their bridging function and study their evolution over time. We apply these tools to the regional and national levels in Germany. Our findings indicate that large patenting regions are not necessarily the ones that embed most new technologies in their knowledge space. For the German knowledge space we find that during the past two decades, it became less dependent on prominent technologies, such as transport, machinery and chemicals. Changes in the German knowledge space in terms of the development of new bridging technologies can be attributed to a regionally dispersed process rather than one driven by single regions.
