국가 R&D 특허성과의 기술융합 네트워크 분석

Purpose The purpose of this study is to analyze the changes in the technology convergence network of national R&D patent performance and the differences in technology convergence research trends between independent R&D and collaborative R&D. Methods Co-occurrence networks have been established in which multiple International Patent Classification (IPC) codes appear per patent in 2014 and 2017. Then, network analysis methods and QAP (Quadratic Assignment Procedure) analysis methods have been used in this study. Results As a result, this study shows that the degree of linkage between technologies related to national R&D projects has increased over time. The main fields of technology convergence research have been changed to ICT fields such as digital and data (G06Q, G06F) and bio fields such as food (A23L) and cosmetics (A61Q). The Ministry of Agriculture, Food and Rural Affairs actively conducts convergence research by introducing new technologies such as ICT. The Ministry of Health and Welfare actively conducts convergence research in the field of bio-health. Conclusion This study showed the changes and characteristics of technology networks of convergence R&D and collaborative R&D. The results of this study are expected to be used as a guideline for decision making in the government's R&D policies.
