Inter-technology networks to support innovation strategy: An analysis of Korea’s new growth engines

Abstract As the interactions between technologies increase during the innovation process, which is well described in the concept of fusion technology or a multi-technology industry, recent innovation research has given much attention to inter-technology networks. This study reviews two techniques to develop such networks using patent data, a patent interaction network (PIN) and a patent citation network (PCN). This review’s purpose is to understand their features and to argue that the two techniques can be complementary. It also tries to explain how the techniques can be used individually and collectively to provide useful information for innovation strategy through a case study. The case study focuses on Korean innovation strategy and the relations between 17 new growth engines announced by the Korean government. The analysis of the results is expected to help understand the hidden dynamics of technology interactions during the innovation process and will ultimately support to develop innovation strategy.
