基于文献和专利分析的海洋工程与技术热点识别及发展态势研究

Research on the Identification and Development Trend of the Ocean Engineering and Technology Hotspots based on Literature and Patent Analysis

识别和分析海洋工程与技术领域热点及其发展态势,能够为我国相关产业发展提供重要情报信息。本文借助CiteSpace软件,对文献和专利数据进行关键词聚类与频数增长研究,识别出海洋工程与技术研究热点;并通过S型增长曲线分析技术成熟度、利用Innojoy专利价值指标分析技术竞争力,从而确定了热点技术的发展态势。结果表明,海洋工程与技术热点主要包括动力推进、电力系统、目标探测与预测、防腐涂层、雷达系统、油气勘探与处理、运动与结构响应以及可再生能源开发。根据这些技术所处的发展阶段与国际竞争格局,提出我国处于成熟期但竞争力落后的技术应走自主研发道路、最大化产业链价值,位于成长期而竞争态势明朗的技术应拓宽市场、不断提升产品性能与服务水平,成熟期且竞争力较高的技术应稳固市场、简化系统、进行技术融合等发展建议。

Identifying and analyzing the hotspots and development status in the field of Ocean Engineering and Technology can provide important information for the development of related industries in China.With CiteSpace software,identify hotspots through the keyword clustering and frequency growth analysis of literature and patent data in the field,then through the S-shaped growth curve,the technology maturity is obtained,and the Innojoy patent value index is used to analyze the technical competitiveness,so as to determine the development stage and trend of the hotspots.The results find eight current technology hotspots in Ocean Engineering and Technology concluding engine and propulsion,power equipment,target detection and prediction,anti-corrosion coatings,radar systems,oil and gas exploration and processing,motion and structural response,and renewable energy development.based on the historical development and the international competitiveness of these hotspots,it is suggested that researching and developing independently and maximizing the value of the industrial chain for the technology in the mature stage but with backward competitiveness,broadening the market and continuously improving the product performance and service level for the technology which is competitive in the growing stage,and stabilizing the market,simplifying the system and integrating the technology for the technology which is competitive in the mature stage.
