- 摘要:
- 采用文献计量分析与专家分析相结合的方法,对白菜发明专利技术信息进行分析。结果表明:中国和国外白菜发明专利申请量变化均经历了萌芽期、缓慢增长期、快速增长期和下降期,国外各时期变化均比中国发生的早。与国外相比,中国白菜发明专利技术研究仍然处于相对活跃状态。中国白菜发明专利申请数量最多的领域依次为栽培、贮藏加工和生物技术,国外最多的领域依次为贮藏加工、生物技术和育种。对中国白菜发明专利文献细分技术方向进行发展趋势分析,种植技术和土壤肥料方面的专利申请数量最多,而育种制种技术、分子标记、采收和种植机械化等方面的专利申请量近期增加明显,为专利技术研究的热点方向。
- Abstract:
- The technical information of Chinese cabbage invention patents was analyzed using bibliometric analysis combined with expert analysis.The results showed that the changes in the number of Chinese cabbage invention patents both in China and abroad have gone through the initial stage,the slow growth stage,the rapid growth stage and the decline stage,and the changes in foreign periods were earlier than those in China.Compared with foreign countries,in China the research of Chinese cabbage invention patent technology was still relatively active.In China the fields with the largest number of Chinese cabbage invention patent applications were cultivation,processing and biotechnology in turn,and in foreign countries were processing,biotechnology and breeding.The development trend of Chinese cabbage invention patent literature was further analyzed by subdividing the technical direction.The results showed that the numbers of patent applications in planting technology and soil fertilizer directions was the largest,while the numbers of patent applications in breeding and seed production technology,molecular markers,plant and harvest mechanization directions increased significantly during recent years,indicating that these research directions were the current research focus of Chinese cabbage invention patent technology.
