基于专利情报分析的中国大黄鱼产业技术创新探析

On technological innovation of Larimichthys crocea industry in China based on patent intelligence analysis

大黄鱼是中国海水鱼类养殖的重要品种之一,技术创新在推动大黄鱼产业规模扩大方面发挥了积极作用。借助专利情报分析方法,对1997—2018年中国大黄鱼专利申请信息进行分析,探讨大黄鱼技术创新发展特征,具体表现为:高等院校和科研院所是大黄鱼专利申请的重要主体;大黄鱼专利申请量与养殖产量在不同省份呈现不协调发展;饲料、加工和养殖技术仍是短期内专利申请的重点领域。通过人工标引方式,对中国大黄鱼专利申请文献信息进行了关键词提取,并从养殖、饲料、加工、质量安全和绿色发展等技术领域绘制了中国大黄鱼专利技术信息的知识图谱。最后,提出鼓励企业加大大黄鱼科技创新力度、推动大黄鱼主产省份的全产业链专利技术布局、开展大黄鱼深远海养殖项目的系统性试验等建议,以促进中国大黄鱼产业实现高质量发展。

Larimichthys crocea is one of the important varieties of marine fish aquaculture species in China,and technological innovation has played an active role in promoting the expansion of Larimichthys crocea industry.The patent application information of Larimichthys crocea in China from 1997 to 2018 was analyzed by using patent intelligence analysis method,and the characteristics of technological innovation and development of Larimichthys crocea were analyzed.The specific performances were as follows:universities and research institutes were important subjects of Larimichthys crocea patent applicants;the number of Larimichthys crocea patent applications and aquaculture production were unevenly distributed in different provinces;feed,processing and aquaculture technologies were still the focus of patent applications in the short term.Through the manual indexing method,the keyword extraction of the Chinese Larimichthys crocea patent application literature information was carried out,and the knowledge map of the patent information of Larimichthys crocea was drawn from the technical fields of culture,feed,processing,quality safety and green development.Finally,it is proposed to encourage enterprises to intensify the scientific and technological innovation of Larimichthys crocea,promote the patent technology distribution in the whole industry chain of the major Larimichthys crocea provinces,and carry out systematic experiments on the deep sea aquaculture project of Larimichthys crocea to promote the high quality development of Larimichthys crocea industry in China.
