摘要
[目的/意义]知识的分化、重组、融合是激发科学创新、促进科学发展的重要动力。基于知识重组视角,揭示知识边界跨越特征与被引量的因果机制对知识扩散研究具有重要意义。[研究设计/方法]通过倾向值匹配的方法,基于科学计量学领域5本期刊2011-2015年的论文及双向引用数据,从知识主题的层面检验边界跨越论文对其被引数量的影响。[结论/发现]边界跨越对论文的被引量有积极效应,边界跨越程度高的论文平均比跨越程度低的论文超出9次左右的被引量。平衡性及共同区间表明了匹配结果的有效性和可靠性。[创新/价值]揭示科学论文边界跨越特征与引文量的内在关系,为解构交叉科学知识流动、解析知识演化提供必要的实证支撑。
[Purpose/Significance]The differentiation,combination and fusion of knowledge are the driving force to stimulate scientific innovation and promote the development of science.This paper is concerned with the causal mechanism between boundary-spanning knowledge and citation counts based on knowledge combination perspective,which is of great significance for knowledge diffusion research.[Design/Methodology]Using propensity score matching,based on 2,860 papers of 5 journals in Scientometrics field during 2011-2015,and their backward as well as forward citation records,this research examines the impact of boundary-spanning papers on citation counts from the knowledge topic level.[Findings/Conclusion]The research results show that boundary-spanning has a positive effect on the citations of papers.Papers with a high degree of boundary-spanning may be cited about nine times more than papers with a lower degree boundary-spanning.The balance and common interval indicate the validity and reliability of the matching results.[Originality/Value]This paper reveals the internal relationship between the boundary spanning feature of papers and their citation counts,which provides necessary empirical support for exploring the flow of interdisciplinary knowledge and explaining the evolution of knowledge.
