全球经济海藻专利研发态势研究

Global patent analysis of economic seaweed

研究全球经济海藻领域专利研发态势,为中国经济海藻技术研发提供参考。基于德温特专利数据库,采用Derwent data analyzer、Derwent innovation等分析工具和平台对1960—2020年经济海藻领域的专利文献进行分析。系统揭示半个多世纪以来经济海藻的全球专利数量变化趋势、专利技术构成、代表国家或地区、主要专利权人、热点技术分布与变迁等内容,同时以产业链为分析视角,梳理热点技术的上、中、下游区位,并通过国际间对比分析得到中国在经济海藻领域技术研发面临的机遇与挑战。中国在经济海藻领域的产业链上游(如海藻栽培)、产业链中游(如药物制剂的治疗活性和提取技术)和产业链下游(如食品烹饪、添加与保存、饲料、肥料和医疗制剂等领域)占据优势,与韩国和日本的产业竞争主要存在于产业链下游,如化妆品、个人护理品和生物杀菌剂等领域,当前缺乏对生物燃料、节能环保和环境修复的研发与关注。

To present recommendations for the R&D of economic seaweed and layout in China,this study examines the patent data of global economic seaweed.Based on the Derwent patent database,the study reveals the global R&D trends in the patent technology for economic seaweed from 1960 to 2020 using the Derwent Data Analyzer,Derwent Innovation,and other tools or platforms.We consider quantitative trends,technology structures,specific countries/regions,main patentees,and distribution and changes in hot technology.From the aspect of the industry chain and through the analysis of the competitive situation of countries/regions in the field of economic seaweed,the study draws conclusions on the position of hot technology in the industry chain and the opportunities and challenges for China in the field of economic algae.China is advantageous in the upstream(e.g.,seaweed cultivation),midstream(e.g.,therapeutic activity and extraction technology of pharmaceutical preparation),and downstream(e.g.,food cooking,addition,and preservation;feed,fertilizer,and medical preparation in the field of economic seaweed)of the industry chain.The industry competition among China,South Korea,and Japan mainly exists downstream of the industry chain,such as cosmetics,personal care products,and biological fungicides.Notably,China may need to pay increased attention to special issues such as biofuel,energy conservation,and environmental protection and restoration.
