基于“反向引用”视角的中国专利技术与世界科学关联分析

An Exploratory Study of the Relation Between Chinese Patents and World Science Based on Reverse Citation

[目的 /意义]论文引用专利的"反向引用"也是科学与技术知识关联的重要体现。针对现有"反向引用"研究的不足,分析中国专利技术对世界科学研究的影响。[方法 /过程]搜集整理中国专利被世界科学论文引用的数据,利用文献计量学方法分析"反向引用"的引用频数、技术关联度、引用时滞及技术循环周期等指标,利用社会网络分析方法构建"反向引用"网络,探讨技术领域到科学领域的知识流动情况。[结果 /结论]中国专利技术对世界科学研究的影响力越来越大。科学与技术的双向互动在化学领域体现的最为明显,化学、工程、材料科学三个学科领域较多地吸收了专利知识,技术关联度较高。前1-4年的技术对当前科学影响最大,中国专利被科学文献引用的循环周期较短,平均为4.69年。

[ Purpose/significance ] The reverse citation of papers citing patents is important in the study of linkage between science and technology. This paper analyzed the influence of Chinese patent on world science fields. [ Method/ process]The data of citations of Chinese patents referenced in articles were collected from Web of Science （WoS） of Thomson Reuters. Reverse citation frequency, technology linkage （TL）, citation delay and technology cycle time （TCT） were analyzed. By the Social Network Analysis （SNA） method, the reverse citation network was constructed and the knowledge flow of technology - to - science was explored. [ Result/conclusion ] The influence of Chinese patent on world scientific research has been growing. The field. Chemistry, engineering and material interaction between science and technology is the most obvious in chemistry science fields have cited patents more, and the technology linkage （TL） is higher than other fields. Scientific papers were more likely to cite patents published within one to four years. The technology cycle time （TCT） of Chinese patents cited by scientific papers is short, with an average of 4.69 years.
