科研人员为了筛选出近期文献,在检索时习惯性选择以某年年初为起点进行检索,本文认为正是这种习惯导致了年底发表文献的影响力小于年初发表的文献,本文称之为“影响力陷阱”。本研究以《经济研究》2001年第1期到2010年第12期的文献为例进行实证分析,并得出结论:在杂志社主编没有刻意将核心著者的文献安排在年初发表的情况下,年末发表的文献在下载频次和被引次数上均显著小于年初文献。 Researchers in order to filter out the recent literature, the habitual choice of retrieval at the beginning of a year as a starting point for retrieval, this paper believes that it is this habit led to the end of the publication of the literature is less influential than the beginning of the publication of the paper, this article called “ Impact Trap ”. In this study, we use the literature of “Economic Studies” from 2001 to the twelfth in 2010 as an example for empirical analysis, and come to the conclusion: in the magazine editor does not deliberately arranged the core author’s literature at the beginning of the case, The published papers at the end of the year were significantly less than those at the beginning of the year in frequency of download and number of citations.
