국내 항만산업의 기술융합 분석 및 R&D 전략 수립 연구

초록

The port industry has experienced significant technological convergence in areas such as smart ports, automated logistics, eco-friendly technologies, and security and surveillance systems. This study aims to identify key technology groups for the port industry in Korea by conducting an IPC code-based patent network analysis and to propose technology convergence structures and R&D strategies. Patent data related to Korea’s port industry were collected and analyzed using network centrality based on IPC code co-occurrence frequency. The analysis identifies the IPC codes G06Q (data processing), G08G (traffic management), B63B (ship structures), E02B (port construction), and H04N (image surveillance) as crucial drivers of technology convergence. The Degree Centrality analysis verifies that technologies related to smart ports and automated logistics are pivotal in this convergence. Betweenness Centrality analysis indicates that ship-derived and automated control technologies play essential roles as intermediaries among different technologies. Furthermore, Closeness Centrality analysis suggests that big data and AI, applied to port operations, have a high potential for facilitating technology diffusion. Consequently, this study recommends R&D investments targeted at these key technology groups, optimized patent portfolios, international technology collaborations, and standardization strategies. These proposed methods and strategies are likely to boost technological innovation in the port industry and enhance its global competitiveness.
