Outline of Final Research Achievements

The project aims to clarify the nature of innovation in the field of information and communication technology, referring to the concept of National Innovation Capacity (NIC). The study was carried out to clarify NIC related structure from multiple aspects. For example, the project analyzed innovation networks based on co-assigned patent data of USPTO. The analysis showed that in the 2010s, knowledge network across organizational boundaries have become limited and those networks might have been sparse. The study also analyzed the impact of blockchain technology on corporate innovation. An autonomous and decentralized organization, DAO, transcends the concept of a country and operates its services by anonymous participants and may have a significant impact on NIC and related governments’ policies. Based on multiple empirical studies, this project as a whole has clarified the nature and transformation of the innovation system in the field of information and communication technology.
