早期引文扩散深广度对论文后期扩散强度的影响
The Effect of Earlier Citation Diffusion Depth and Breadth on Later Diffusion Intensity of Scientific Papers
摘要
Abstract
[Purpose/Significance]This study sorts out and defines the concepts of citation diffusion depth and breadth,and explores the effects of citation diffusion depth and breadth characteristics in the earlier stages of a paper's pub-lication on the citation diffusion intensity in the later stages,in order to enrich the explanation of the mechanism of correla-ting the characteristics of a paper's earlier citations with its later citations.[Method/Process]This study collected the bib-liographic data of scientific papers published in 3 journals in 2013 from each of 50 subject categories,as well as the biblio-graphic data of their earlier citing literatures,to construct earlier ego citation networks for the target papers.The paper de-fined the citation diffusion depth as the average cascade depth of citations and the citation diffusion breadth based on Brillouin's Index from three dimensions:discipline breadth,regional breadth,and author breadth.And the paper used a negative binomial regression model and Double/De-biased Machine Learning method(DDML)to analyze the relationship between the depth and breadth of earlier citation diffusion and the later diffusion intensity of papers.[Result/Conclusion]Earlier citation diffusion depth shows a significant negative effect on the later diffusion intensity under both 2-year and 3-year citation windows,while earlier citation diffusion discipline breadth shows a positive effect on later diffusion intensity under both citation windows.Regional breadth shows a positive effect on later diffusion intensity of papers under the 2-year citation window,but doesn't show significance under the 3-year citation window.Author breadth shows a significant posi-tive effect on papers in low-cited group,but has a negative impact on papers in high-cited group.关键词
