期刊影响因子的影响因素分析

期刊的影响因子是期刊学术影响力的一个重要评价指标,但单纯依靠该指标对期刊进行学术评价有失偏颇。文章从影响因子的定义出发,对影响期刊影响因子的主客观因素进行了分析。结果表明,客观因素中,学科间差异和统计时段的影响无规律可循;综述类期刊和综述性文章比重大的期刊影响因子普遍高于其他期刊;期刊的刊文数量和作者数量越多,影响因子越大;统计样本越多,期刊的影响因子越大。主观因素导致的期刊影响因子增大不能体现期刊的学术影响力。在对期刊的学术水平进行评价时,如果以“他引影响因子”作为评价指标,或将影响因子作为目标函数,他引率和扩散因子作为约束条件,从而优化出评价指标应该更为客观与公正。

An Analysis of Affecting Factor of Journal's Influencing Multiplier

Journal's influencing multiplier is one of the important evaluating indicators to evaluate its academic influence.But the influencing multiplier is not the only academic evaluation criterion.Based on the definition of the influencing multiplier,both subjective and objective influencing factors for the influencing multiplier are analyzed in this article.The result indicates that in the objective factors,the influences of subject diversities and statistics time interval are ruleless.The influencing multiplier of overview journals and journals with majority of overview articles is higher than that of the other journals.And also,the journal's influencing multiplier will grow with the increase of papers',writers'and statistic samples'amount.The increase of influencing multiplier derived from subjective factors could not embody the academic influence.If using the referenced-by-others influencing multiplier or the optimized evaluation criterion by use of influencing multiplier as target function and referenced-by-others frequency and divergence factor as boundary conditions,this evaluation will be more objective and fair.
