Key Indicators of Journal Evaluation Based on K-means and PLS-DA

[Purpose/Significance] There are many evaluation indicators and methods for journal evaluation, and it is of great significance to study the importance of evaluation indicators of journals. This paper proposed an analysis framework for "post-event" analysis of the importance or weight of evaluation indicators. [Method/Process] This paper divides the journal evaluation indicators into "before" importance and "after" importance, and focuses on the "after" importance, that is, the determination of key indicators after objective cluster analysis. Taking the bibliometric indicators of JCR 2019 economics journals as the research object, K-means clustering was first used to obtain the classification of evaluation results, and then the key indicators of journal evaluation were calculated based on principal component analysis and partial least squares discriminant analysis, and the importance of each indicator was analyzed. Starting from the objective results and the meaning of the indicators themselves, this study ex
