Abstract:[Purpose/significance] Journal source indicators have been a hot issue in the academic communityBased on the timevarying parameter state space equation,the paper compares and analyzes the relationship between source indexes from the dynamic perspective[Method/process] Based on the Chinese Social Science Citation Index (CSSCI) as the data source database,this paper selects the source literature index data of 13 periodicals in library and information science from 2005 to 2018Through the grey correlation degree analysis,three indexes with strong correlation with the source literature volume are selectedAccording to the state space equation of timevarying parameters,the influence of indexes is compared[Result/conclusion] The first three correlations with the source literature amount from large to small are the ratio of fund papers,the number of regional distribution and the number of institutions distributionThere is a negative correlation between the amount of source literature and the ratio of foundation papers,and the negative correlation becomes stronger with timeThe results showed a positive correlation with the regional distribution and the institutional distribution,and showed an increasing trend with the passage of time
