From recombination to diffusion: Exploring the impact of knowledge recombination characteristics on geographical knowledge diffusion

In an era marked by rapid technological advancements and global interconnectedness, understanding how knowledge traverses geographical boundaries is crucial for fostering innovation. This study examines the relationship between knowledge recombination and geographical knowledge diffusion, employing empirical research using patent data from FDA-approved pharmaceuticals. It uncovers that the intensity of knowledge recombination, as denoted by the reference count, and its breadth, as indicated by the knowledge originality index (which captures the 'technological' scope) and the backward citation geographical distance (illustrating the 'geographical' scope), are key factors driving the diffusion of knowledge across geographical regions. These findings are pivotal as they reveal how the depth and range of knowledge recombination significantly influence the spatial spread of technological insights. This research makes a unique contribution to existing literature by shedding light on the impact of knowledge recombination on geographical knowledge diffusion.
