Abstract: In order to clarify the development status of rapeseed industry technology, using Innography patent analysis platform, this paper analyzed the global patent development trend of rape industry, major countries and innovative institutions, main IPC and technical hotspots, and patent intensity by patent data mining method. The paper also presented the innovation status of this technology by visualized method. The results showed that after 2013 the global rape industry had gradually entered the stage of technological aging period through experiencing technology germination and maturing stages. Mainland and Taiwan province of China were the important target markets for patent layout of the United States and Japan. The key technologies of rape industry were mainly concentrated in C12N, A01N, A61K and etc. subcategories. Chinas invention and innovation covered most of the technical hotspots, but there were still some hot areas lacking sufficient coverage. The U.S. patents intensity was far ahead, while the innovation of Chinas patent technology was facing challenge. Before ending, the paper put forward countermeasures and suggestions for promoting the sustainable development of rape industry in China.

摘要： 为明晰油菜产业技术发展现状，采用Innography专利分析平台，通过专利数据挖掘对油菜产业全球专利发展态势、主要国家、重点创新机构、主要IPC和技术热点、专利强度进行了分析，并用可视化的方法展示了该技术领域的创新状况。结果表明：全球油菜产业发展在经历技术萌芽期、技术成熟期后， 2013年后逐渐进入技术衰老阶段；中国大陆和台湾是美国、日本等国专利布局的重要目标市场；油菜产业关键技术主要集中于C12N、A01N、A61K等小类；中国的发明创新覆盖了大部分技术热点，但仍有部分热点领域覆盖度不足，美国专利强度遥遥领先，中国专利技术创新仍面临挑战。研究提出了促进我国油菜产业持续发展的对策建议。
