文献颠覆性创新测度——权重颠覆性指数

Measurement of Disruptive Innovation in Academic Papers:Weighted Disruption Index

[目的/意义]为解决传统颠覆性指数计算过程中不考虑焦点文献的参考文献数量的问题,提出权重颠覆性指数(权重D指数),有助于更加合理有效地评估文献的创新性。[方法/过程]提出一种针对焦点文献的参考文献数量的调整方法——权重颠覆性指数,以1950—2023年获得化学诺奖及其对照组的论文为数据来源,一方面,从合理性与有效性两方面对比颠覆性指数与权重D指数;另一方面,针对一篇焦点文献的参考文献被其引证文献多次引用的情况,具体分析焦点文献的创新性、焦点文献的影响力、焦点文献的参考文献的影响力与焦点文献的参考文献收到引用数量的相关性。[结果/结论 ]权重D指数具有合理性,且比传统颠覆性指数更能有效识别论文的创新性;当焦点文献的创新程度和影响力越高时,引证文献越倾向于引用其参考文献;当焦点文献的参考文献影响力越高时,引证文献也倾向于引用其参考文献。

[Purpose/Significance]Since the traditional disruption index calculation does not consider the number of references in the focus paper,this study proposes the weighted disruption index(the weighted D index)to evaluate the innovation of the papers more reasonably and effectively.[Method/Process]This study adopted a method for adjusting the number of references in focus papers,the weighted disruption index.It took the papers that won the Nobel Prize in chemistry from 1950 to 2023 and their control groups as data sources.On the one hand,it compared the disruption index and weight D index from the rationality and effectiveness.On the other hand,in view of the fact that the reference of a focus paper was cited several times by its citing papers,it specifically analyzed the innovation and the influence of the focus paper,the correlation between the reference influence and the number of reference citations.[Results/Conclusion]The weighted D index is reasonable and can identify the innovation of a paper more effectively than the traditional disruption index.When the innovation degree and influence of the focus paper are higher,the citing papers are more likely to cite its references.When the reference influence of the focus paper is higher,the citing papers also tend to cite its references.
