摘要

We create an intersectoral citation network using 1.3 million patents granted between 1981 and 2010 across all industries in the United States. In this network space, we find a significant increase over time in the proximity of non-information and communication technologies (ICT) industries to the ICT industry. Such ICT-closeness of an industry relates to a significant increase in the proportion of ICT technologies in the industry's patent portfolio and complementarity between ICT and non-ICT patents in its portfolio. We hypothesize and find that ICT-Closeness has a significant positive impact on innovation outcomes of the citing industry, including innovative efficiency, recombinant capabilities, and creation of new products, services, and business methods. ICT-closeness also engenders hypercompetition in the citing industries, as reflected in greater winner-take-all dynamics and turbulence. Our results point to a paradigm shift in knowledge production, and in turn, sources of competitive value across diverse industries.
