越来越多的实证数据显示,中国科研发表的被引频次正在迅速上升。不同的解释相继提出。本研究探讨了另一种可能性———中国研究的被引频次激增是否存在“俱乐部效应”,②即高影响力的中国科研论文会有更高的内部援引率。以纳米技术这一交叉新兴领域作为研究素材,我们发现中国高被引论文在个体、科研机构以及国家三个层次上较大比例的引用来源于内部网络。描述性和统计检验表明,与美国同类论文相比,中国高被引论文的内部引用更为显著。文末就该“俱乐部现象”进行了诠释并提出相关政策建议。%There is increasing evidence that citations to Chinese research publications are rising sharply.A series of reasons have been highlighted in previous studies.This re-search explores another possibility-whether there is a “clubbing”effect in China’s surge in research citations,in which a higher rate of internal citing takes place among influential Chinese researchers.Focusing on the most highly cited research articles in nanotechnolo-gy,we find that a larger proportion of Chinese nanotechnology research citations are local-ized within individual,institutional,and national networks within China.Both descriptive and statistical tests suggest that highly cited Chinese papers are more likely than similar U.S.papers to receive internal and localized citations.Tentative explanations and policy implications are discussed.
