Two faces of scientific knowledge in the external technology search process

Scientific knowledge enhances the process of external technology search, which is key to generating technological innovations. We propose the interaction effects of scientific knowledge with two technology search dimensions: external technology search intensity (scale) and external technology search scope. We examine these interaction effects in the generation of technological outcomes by comparing between sectors with creative accumulation (hydrogen energy) and creative destruction (nanotech). Data on the U.S. patents and their citations were collected to measure external technology search activities and degree of scientific knowledge in generating technological outcomes. We find that scientific knowledge and high external technology search intensity jointly increase technological outcomes in the sector with creative accumulation and scientific knowledge and broad external technology search scope jointly increase technological outcomes in the sector with creative destruction.
