abstract

In addition to internal R&D, external knowledge is widely considered as an essential lever for innovative performance. This paper analyzes knowledge spillovers in supply chain networks. Specifically, we investigate how supplier innovation is impacted by buyer innovation. Financial accounting data is combined with supply chain relationship data and patent data for U.S. firms in high tech industries. Our econometric analysis shows that buyer innovation has a positive and significant impact on supplier innovation. We find that the duration of the buyer–supplier relationship positively moderates this effect, but that the technological proximity between the two firms does not have a significant effect on spillovers.

7. Conclusion

This study provides novel empirical evidence on knowledge spillovers in supply chains. We analyze knowledge spillovers between buyers and suppliers, as well as central factors that govern this phenomenon. We find both statistically and economically significant evidence that buyer innovation positively influences supplier innovation. We also show that knowledge spillovers from buyers to suppliers are positively moderated by the duration of the relationship between the two firms. The results do not support the hypothesis that knowledge spillovers increase the more similar a supplier is to its buyers in terms of technology.
