This paper applies a demographic characteristics perspective to understand the internal contingencies of the relationship between university-industry collaboration (UIC) motivation (commercialisation, learning, accessing the resources, and teaching) and UIC performance (number of publications, number of patents, commercial products, and number of business cooperation cases). The paper focuses on two aspects of demographic characteristics, age and gender among UIC scholars, and their effect on scholars’ UIC motivation as potential enhancements to improve UIC performance. We collected data from 376 scholars with UIC experience in Taiwan, and the proposed hypotheses were empirically tested. Our results extend the literature by showing that specific categories of UIC performance depend on a scholar's specific type of UIC motivation. We also specify the moderating effect of demographic characteristics on the relationship between specific subconstructs of UIC motivation and UIC performance. The study’s implications and future research directions are discussed.
