摘　　要：基于专利数据揭示谷物联合收割机技术的全球布局、研究热点以及竞争态势,为中国联合收割机技术挖掘、产业化发展提供参考。以谷物联合收割机为研究对象,基于IncoPat专利数据库,从专利整体布局、技术申请趋势、专利申请机构、高价值专利分析等方面剖析联合收割机技术领域的全球创新布局和竞争力态势。近年来,全球联合收割机技术进入新一轮创新活动活跃期,日美中德4国专利申请量占全球的86.95%。中国专利申请在数量上与美日等国差距不断缩小,但高价值专利较少。久保田、井关农机、迪尔公司、CNH全球有限公司等国际农机巨头是谷物联合收割机技术创新的主要企业。中国技术研发关注联合收割机的控制和测量装置,而谷物分离清选还需要进一步加强研发以追赶世界先进水平。中国谷物联合收割机面临国际农机巨头的专利封锁,海外布局专利不足,高价值专利数量少,国内企业竞争力不足等问题。我国在该领域应发挥后发优势,积极利用失效专利合理开展专利布局,加强高校和科研机构与企业合作推进技术成果转化。Based on patent data,we revealed the global technical distribution,research topics and competition trend of grain combine harvester technology.It provided reference for the technology mining and industrialization development of grain combine harvester in China.Based on IncoPat patent database,we analyzed the global innovation layout and competitiveness of grain combine harvester from the perspectives of patent overall layout,patent application trend,patent applicant and its research topics.The results showed that the technology of combine harvester entered a new round of innovation activities in recent years.The patents from China,the United States,Japan and Germany accounted for 86.95%of the total world.The gap between China and advanced technology countries in patent application narrowed.International agricultural machinery giants,such as Kubota,Iseki,Deere Company,CNH Industrial,were the main enterprises of grain combine harvester technology innovation.Great attention had been paid to the control and measurement devices of combine harvesters in China,and further research were needed to catch up with the world’s advanced level in grain separation and cleaning.In addition,China’s grain combine harvester innovation was facing problems like patent blockade from international agricultural machinery giants,low share of high-value patents,insufficient patents distribution overseas,and weak technological innovation competitiveness of domestic enterprises.In the future,China should take the advantage of backwardness,and carry out patent layout with invalid patents.Furthermore,cooperation among universities,research institutions and enterprises should be strengthened to promote the transformation of technological achievements.
