특허 인용 네트워크 기반 자율운항선박 기술의 축적 경로와 기술 전환 분석

초록

Autonomous ships have emerged as a core technology amid structural changes in the maritime industry, including labor shortages, safety demands, and carbon neutrality. As autonomous ship technology is realized through the integration of multiple technologies such as sensors, control, communication, and Al, a system-level perspective is required. This study applies Main Path Analysis(MPA) and Persistence analysis based on a patent citation network to identify major technological trajectories and transitions. The results indicate that the technology has evolved along four pathways-platform development, operational stabilization, industrial application, and operating-system-based integrated management (Paths A-D). Core patents in each period served reference points through repeated citation, and recent trends reveal a paradigm shift from equipment-level technologies toward system-centric approaches such as data integration and multi-platform management.
