Though spillover potential has been identified for the betterment of economic growth, the studies on necessary infrastructures to induce spillovers is still in their early stages. This paper discusses how integrating technologies function as spillover infrastructures in the advanced stage of technological development. Taking the case of robotic technology as an integrating technology, this paper argues the important role of certain integrating technologies in creating a medium for knowledge distribution in an innovation system. Utilizing the Techno-Economic Network framework, this paper provides empirical evidences to show how the robotic technology in Japan, has been functioning as an invisible infrastructure to induce spillovers. This paper concludes that as intangible factors becomes important for building technological infrastructure, identifying the characteristics of integrating technologies in national systems will be an important policy issue.
