ABSTRACT
Research and development (R&D) collaboration becomes essential as technology becomes more complex, and technological change occurs at an unprecedented rate in high-tech sectors such as information and communication technologies (ICT). However, no concrete evidence exists on the benefits of collaboration diversity in terms of government support. Therefore, this study investigates whether a firm’s innovation increases not only as R&D collaboration partners’ diversity increases but also as firms engage in crosssectoral R&D collaboration. Government subsidies for ICT firms that collaborate with other firms and research institutions at the same time have significantly positive effects on firm performance. Interestingly, cross-sectoral collaborations increase innovation activity. The results suggest that firm innovation can be efficiently achieved through R&D partner diversity, and the R&D subsidy scheme needs to focus on collaboration with diverse R&D partners with different knowledge to generate innovative outcomes.
