[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 “citation of back” cited in the paper is also an important manifestation of the connection between science and technology knowledge. Aiming at the deficiency of the existing “reverse reference” research, this paper analyzes the influence of Chinese patent technology on the world scientific research. [Methods / Processes] Collect and collate the data of Chinese patents cited by the world’s scientific papers and analyze the quoted frequency of “reverse quotations”, the degree of technical relevance, the reference delay and the technical cycle period by using bibliometrics methods, Web analytics builds a network of “reverse references” to explore the flow of knowledge from technology to science. [Result / Conclusion] Chinese patent technology has more and more influence on world scientific research. The two-way interaction between science and technology is most obvious in the field of chemistry. The fields of chemistry, engineering and materials science have absorbed most of the patent knowledge and the technology has a high degree of correlation. The first 1-4 years of technology have the greatest impact on the current science. Chinese patents are scientifically cited for a short cycle of 4.6 years, an average of 4.69 years.
