Let's Talk! The Impact of a Scientist's Integrative Knowledge Network on Breakthrough Innovation

ABSTRACT Breakthrough innovation relies on integrating knowledge through networks, yet extant research often examines inventor and knowledge element networks in isolation, obscuring the individual‐level mechanisms of recombination. We bridge this gap by conceptualizing the integrative knowledge network as an individual's cognitive blueprint for breakthrough innovation. Using data from top biochemical scientists at a leading US oil and gas firm, we find that the depth of the network has no significant direct effect on breakthroughs. Conversely, our analysis reveals an inverted U‐shaped relationship between the breadth of the network and breakthrough innovation, which is significantly moderated by weak ties. Our study demonstrates that breakthrough innovation arises from combinatorial potentials that emerge as individuals actively seek knowledge from colleagues through integrative knowledge networks.
