基于专利信息的中国粮油产业技术研发态势分析

摘要

粮油安全是国民经济发展和社会全局稳定的重大战略问题.以中国国家知识产权专利数据库作为数据来源,采用SOOPAT专利数据库搜索引擎作为检索工具,对中国1986-2015年粮油产业的技术生命周期及其专利申请趋势、专利技术构成、热点专利、各国来华申请专利情况、专利的法律状态和地区分异进行系统分析.研究结果表明:中国粮油产业处于技术生命周期的成熟期,由最初的重视专利数量转变为注重专利质量的提升;绝大部分专利以职务发明为主,申请人主要是大专院校及科研单位,专利存活期普遍较短;杀虫剂植物生长调节剂、微生物或酶、栽培、播种施肥及植物再生是目前中国粮油产业技术研发的热点领域.%Grain and oil security is a major strategic issue of national economic development and social stability.In this article,taking the Chinese intellectual property patent database as the data source,using SOOPAT patent database search engine as a retrieval tool,analyzes the patent application trend of grain and oil industry from 1986 to 2015,the technology life cycle,patent technology hotspots,national patent application situation,legal status and regional differentiation.The results show that,China's grain and oil industry is in the maturation of technology life cycle,it changes from the initial premium on the number of patents to the improvement of patent quality;most of the patents areservice inventions,and applicants are mainly junior college and scientific research units;pesticide plant growth regulator,microorganism or enzyme,cultivation,seeding fertilizer and plant regeneration are the R&D hotspots in Chinese grain and oil industry technology.
