为研究不同特征因子分值条件下,其与其他文献计量指标的关系,基于JCR 2009年电气电子期刊数据,采用分位数回归进行研究。结果表明,对于特征因子分值较低的期刊,论文影响分值、总被引频次与特征因子呈较低正相关,即年指标与特征因子无关,5年影响因子、被引半衰期与特征因子呈较低的负相关。载文量只在特征因子分值较低时与它呈正相关关系,其他情况无关。对于特征因子分值较高的期刊,论文影响分值与特征因子呈较高的正相关,即年指标与其呈较高的负相关,其他情况特点不明显。研究发现,特征因子分值的引入有利于期刊提高学术质量,但对于其他学科的情况有待进一步研究。
In order to study the relationship between the score of different characteristic factors and other indexes, the quantile regression was used to study the data based on the JCR 2009 Electrical and Electronic Journal. The results showed that for the journals with lower scores of the characteristic factors, the scores of the papers, the total number of cites and the characteristic factors showed a low and positive correlation, that is, the annual index had no relationship with the characteristic factors, and the five-year impact factors, the cited half-lives and the characteristic factors A lower negative correlation. The quantity of the essay is only positively related to it when the score of the eigenvalue is low, and has nothing to do with other cases. For journals with higher scores of feature factors, the scores of paper essay and eigenfactors showed a higher positive correlation, that is, the annual index had a higher negative correlation with the other characteristics. The study found that the introduction of eigenvalue scores is conducive to improve the academic quality of journals, but the situation of other disciplines to be further studied.
