[Purpose/significance] In the evaluation of academic journals, excessive self-citation and artificial manipu ?
lation of article quantity are two important problems, and it is necessary to amend it. [Method/process] The paper pro?
poses to use the variable weight of key index data to prevent the artificial manipulation of the biblimetric indicators.
The basic principle is to punish or motivate the original data of the evaluation index through the variable weight func?
tion, and to include the self-citation and article quantity into the evaluation system to evaluate. [Result/conclusion]
The paper makes an empirical study based on the data of CNKI management journals, the research shows that we must
attach importance to the artificial manipulation of the article quantity and self-citation in academic journals. It can ef?
fectively solve the artificial manipulation of index problem by using variable weight of key index data. The evaluation
system should pay attention to the balance between the evaluation goal and the prevention of artificial manipulation. It
is suggested that excellent journals should expand the article quantity.
