摘　　要：[目的/意义]自引作为一种特殊的引文交流形式,在知识扩散过程中是否更具时效性?这一问题需要在实证研究中加以检验。[方法/过程]以JCR收录的管理学期刊为例,从Web of Science获取2009-2018年10年间的发文和引文数据,从期刊自引角度进行计算,从共时和历时两个维度,分别对自引与他引的引用延时指标的分布及变化规律进行比较分析。[结果/结论]期刊自引较之他引确实更具时效性,自引的引用延时普遍低于他引,其平均值相差5~6年,自引的引用高峰早于他引2年,单篇文献包含的参考文献平均年龄与其自引证率显著负相关,期刊自引较之他引,在捕捉新兴知识、加快知识扩散速度方面具有显著的优势。[Purpose/Significance]As a special form of citation communication,does self-citation have the advantage in the speed of knowledge diffusion?This assumption needs to be verified in empirical research.[Method/Process]Taking the journals under the category of"Management"indexed in the JCR as an example,this paper collects the bibliometrics data of publications and citations during the period of 2009-2018 from Web of Science,and calculates the citation lag of journal self-citations and journal external-citations respectively.The distribution and dynamics of the citation lag of self-citations and external citations are compared and analyzed from synchronic and diachronic aspects.[Result/Conclusion]Self-citations are proved to be more prompt than external citations.The citation lag of self-citations is pronouncedly and generally lower than that of external citations,with the average value differing by 5~6 years.The self-citation peak of self-citations is earlier for 2 years.The average age of references included in a paper is significantly and negatively correlated with the self-citing rate of the paper.Compared with external citations,self-citations have apparent advantage in accelerating new knowledge diffusion.
