学术期刊来源指标与影响力关系的实证研究

摘要：对学术期刊来源指标与影响力关系进行研究，总结其中潜在规律，对期刊评价与期刊管理具有重要意义。从期刊来源指标的角度系统分析其与期刊影响力关系的研究不多。本文利用散点图、回归分析和分组统计三种方法相结合，以中国科学技术信息研究所医学类学术期刊为例，分析了基金论文比、平均引文数、平均作者数、地区分布数、引用半衰期5个期刊来源指标与期刊影响力之间的关系。发现期刊来源指标较好并不代表期刊影响力就很大。各期刊来源指标与影响力之间存在着较低的相关关系，但是在不同数据段他们的相关程度又不一样。不同期刊来源指标与期刊影响力之间的关系各有特点。建议在期刊学术质量评价中舍弃来源指标。

Study on source indexes and influence of the academic journal evaluation

Abstract: It’s very important to study source indexes and influence in the academic journal evaluation and to continuously summarize their rules, howerer, the studies involving this area are quite rare. Adopting the medical journals in the institute of scientific and technical information of China, the relationship among ratio between grant-supported papers and total papers, average references per article, average number of authors, distribution of regions, citing half-life, and impact factor is analyzed based on the dot map, regression, and grouped statistics. The results show that the impact factor and source indexes have lower correlations, but their correlation level is different at the different data segment. The relationship among different journals’ source indexes and impact factor has its own characteristic; therefore source indexes should be given up while evaluating academic journal quality.
