专利视域下全球电动船舶领域格局分析

Analysis of the Global Pattern of Electric Ship Industry from the Per⁃Spective of Patents

【目的】基于专利视角,探索了解全球电动船舶产业技术领域发展现状和产业主体的布局情况,为相关决策主体提供参考。【方法】对全球及中国电动船舶领域进行申请趋势、专利流向和专利技术等专利信息统计分析。【结果】中国在电动船舶领域发展迅猛,占据主导地位,但不注重海外市场的专利布局;美日韩等国在该领域仍具有一定的实力,并且注重全球布局;电动推进技术是全球电动船舶的研发重点;由于行业进入壁垒较高,目前中国的电动船舶领域主要由高等院校和中国船舶集团有限公司主导。【结论】中国在电动船舶领域具有较强的科研实力,未来需注重在海外市场的专利布局,以提升该领域的话语权。同时也需利用现有的汽车电池技术优势,尽早布局电动船舶用电池技术专利。

[Purposes]Through the perspective of patent,this study explores and understands the current status of the development of the global electric ship industry technology field and the layout of the indus-try entities,and provides reference for relevant decision-makers.[Methods]The patent pattern informa-tion such as the application trend,patent flow,and patent technology of the electric ship field in the world and China in the past 20 years are statistically analyzed.[Findings]China has developed rapidly in the field of electric ships and occupies a dominant position,but does not pay attention to the patent layout of overseas markets;countries such as the United States,Japan,and the republic of Korea still have certain strengths in this field and pay attention to the global layout;electric propulsion technology is the global electric ship research and development focus;due to the high barriers to entry in the industry,the current electric ship field in China is mainly dominated by universities and China State Shipbuilding Corporation Limited.[Conclusions]China has strong scientific research strength in the field of electric ships,but it needs to pay attention to the patent layout in overseas markets in the future to enhance the voice in this field.At the same time,it is also necessary to layout the battery technology patents for elec-tric ships as soon as possible by taking advantage of the existing automobile battery technology advantages.
