The Impact of Industry–University–Research Alliance Portfolio Diversity on Firm Innovation: Evidence from Chinese Manufacturing Firms
Innovation is a key factor for the sustainable development of firms. Although it has been a prevalent phenomenon that firms maintain multiple industry&ndash ; university&ndash ; research (I&ndash ; U&ndash ; R) alliances simultaneously to generate innovation, there is a lack of explorations in this phenomenon in extant literature. In this study, we introduce a new construct, I&ndash ; U&ndash ; R alliance portfolio, and investigate the impact of its diversity on a focal firm&rsquo ; s innovation performance. Hypotheses are proposed and examined using datasets of 176 listed firms in the Chinese manufacturing industry. We find that I&ndash ; U&ndash ; R alliance portfolio diversity exerts a positive effect on a focal firm&rsquo ; s innovation performance and a firm&rsquo ; s absorptive capacity positively moderates this relationship. Furthermore, we contend that with increasing levels of government financial support, the positive relationship between I&ndash ; U&ndash ; R alliance portfolio diversity and firm innovation performance is strengthened. Finally, our findings provide several theoretical and practical implications for the I&ndash ; U&ndash ; R alliance portfolio and firm innovation.
