造船產業是產業鏈整合發展的綜合性 工業，主要工業國家均藉由發展造船產業以推動基礎工程科技，帶動相關產業發展及厚植國力。台灣造船產業雖有市場規模不大、土地及人工成本高等不利因素，但若能集中資源研發規劃，將有利於提升造 船技術競爭力。因此，本研究藉由專利分析方法，比較台韓造船產業領導廠商一南韓現代重工及台灣國際造船公司之技術發展現況，探討具有全球造船領導地位的 現代重工技術發展趨勢，以及專利技術布局現況，提供台灣造船產業技術發展之建議。專利資料至2013年8月為現代重工已核 准及公開的769件南韓專利，以及台灣國際 造船公司已核准之7件中華民國專利。分析結果顯示，現代重工專利技術布局多元 且聚焦，著重於製程技術、艤裝設備、船體結構、推進系統及LNG/LPG運輸船等技術研發，以達成提升造船生產力、改善推進效能及提高結構性能等功效，全面性發展節能相關造船技術及提高生產力，藉以維持全球競爭優勢。反觀台灣國際造船公 司在研發資源有限下，雖已研發商業化的節能相關推進技術，但未利用專利保護， 無法形成公司的技術競爭力。最後，研究 建議台灣造船產業應以節能推進技術為技術發展主軸。

Shipbuilding industry is a comprehensive industrial developed with the whole industry chain. Developed countries promoted the shipbuilding industry development policy to improve the infrastructure technology, to develop the related industries and upgrade the national defense competitiveness. The characteristics in Taiwan’s shipbuilding industry compared with the advanced industrial countries are that the market share is small, land and labor costs are high. However, we focus on the core technology development and resource planning to enhance the competitiveness of shipbuilding technology. Therefore, the purpose of this study is to compare the status of technology development of leaders in Taiwanese and Korean shipbuilding industry- Hyundai Heavy Industries and CSBC Corporation, Taiwan by using patent analysis. The results could recommend for technology development of shipbuilding indus-try in Taiwan from analyzing the trend of technology development and the patent portfolio construction in the global shipbuilding company- Hyundai Heavy Industri-es. Hyundai Heavy Industries in South Korea had applied 769 patents from 1992 to 2013 and CSBC Corporation, Taiwan had applied 7 patents in Taiwan. Using the cross table analysis between technology efficacy and technical efficacy, the results showed that the patent portfolio in Hyundai Heavy Industries shipbuilding focused on manufacturing process, rigging equipment, shipbuilding structures, propulsion systems and LNG/LPG carriers. The technical efficacy focused on raising productivity, improving propulsion performance, and improving ship structure. On the other hand, based on the limited R & D resources, CSBC Corporation, Taiwan focus on gre-en energy research of propulsion systems, but had not used patents to protect the invention. Finally, the study suggested Taiwan shipbuilding industry should promote the development of green energy technologies and strengthen the shipbuilding patent-related knowledge construction and patent personnel training.
