This article sets out to investigate the relationship between the knowledge spillovers and the potential for high-value inventions to emerge. We study knowledge spillovers through the lens of knowledge networks: a web of interrelated knowledge elements with structural patterns. Knowledge spillovers influence the productivity of a technology sector and hence their pattern should impact the pathways for knowledge appropriation in the sector. It is hypothesized that a robust knowledge network is associated with knowledge appropriation leading to valuable inventions. We test the hypothesis using patent citation network of 1821 patents from 78 inventions belonging to two different technological sectors. Based upon the findings, we suggest network robustness as a new metric for determining the technical value of inventions. [ABSTRACT FROM AUTHOR]

The main sources of technological development are from abroad rather than domestic in many countries. The global networks for knowledge and technology flows are becoming sophisticated. This article examines how a country's embeddedness in the global knowledge spillover networks, particularly trade and FDI, is related to national innovation performance. Network closure and structural hole, the main arguments in network theory literature, represent the main objectives of our network analysis. The results are subsequently used to assess how these network characteristics are related to national innovation performance via panel negative binomial regression analysis. The findings show an overall tendency of a negative effect of network closure and a positive one of structural holes on a country's innovative outcome. In conclusion, this article not only highlights the significant role of network characteristics in national innovation performance, but also provides implications on how to leverage such network resources to improve national innovation systems.
