4차 산업혁명 기술 기반 산업 간 협력 전략 분석: 정보서비스업·제조업 등록 특허를 중심으로

This study compares the patent collaboration structures of the information service and manufacturing industries based on key Fourth Industrial Revolution technologies. Using jointly filed patents registered between 2020 and 2023, co-applicant networks were constructed and analyzed through centrality, density, and clustering coefficients. The information service industry showed a firm-centric and limited collaboration pattern, whereas the manufacturing industry exhibited active multi-stakeholder networks involving firms, universities, and research institutes. At the technology level, autonomous vehicles demonstrated a closed structure with low density, while 3D printing displayed an open, university- and research-driven collaboration network. These findings reveal clear differences in openness and maturity across industries and provide empirical insights for designing tailored industry academia–research collaboration models and technology commercialization policies. Moreover, differences in collaboration structures can be interpreted as key factors influencing patent performance and technology transfer potential. Furthermore, this study empirically supports the importance of developing collaboration strategies that reflect industry-specific characteristics.
