Abstract: Prior literature has long examined innovation as a recombination process within or across the boundaries of technological domains. However, limited attention is paid to boundaries per se. Building upon recent development of categorical contrast, this study distinguishes domains with crisp boundaries from those with fuzzy boundaries and examines their effects on innovation outputs. Analyzing a large sample of US patents, we find that spanning crisp boundaries is more likely to generate impactful inventions but at the same time leads to significantly higher recombinant uncertainty. We continue to explore what types of inventors are better able to span such types of domain boundaries. Focusing specifically on the role of inventors’ knowledge expertise, we find that while both knowledge depth and breadth enhance the impact of technologies that span crisp boundaries, knowledge breadth is also found to escalate the associated uncertainty. Our emphasis on the contrast of technological domains contributes to the literature on recombinative innovation and boundary spanning.
