국방기술 특허의 융합 수준 비교 분석: 미국 특허와 한국 특허를 중심으로

The purpose of this paper is to compare the level of technology convergence between The USA and South Korea in the field of defense science and technology. This paper utilizes defense science and technology patents registered between 2009 and 2020 from both the United States and South Korea. Social Network Analysis(SNA), Quadratic Assignment Procedure(QAP), and association rule analysis were applied to analyze the level of technology convergence by country. The fields of ships and aircraft, gunpowder and ammunition, and weapons showed different technology convergence characteristics. Over time, the level of technology convergence tended to increase. In particular, in The U.S., the flow and structure of technology convergence have changed, while in South Korea, only the flow of technology convergence has changed. This paper is meaningful in that it comprehensively examines the technological convergence phenomenon between The U.S. and South Korea and presents a method to compare the level of technological convergence. The results of this study are expected to be used as primary data for future technology convergence measurement.
