我国科技期刊引证指标数据库的对比分析与评价

目的 更好地了解我国科技期刊相关引证指标数据库的情况。方法 对科技期刊引证指标数据库（CSCD-JCR）、《中国科技期刊引证报告（核心版）》（CJCR）、万方数据的期刊统计分析与评价、维普资讯的中文科技期刊评价报告、中国知网的个刊影响力统计分析数据库这5个科技期刊引证指标数据库进行对比分析,详细分析比较了其引证指标组成及用于评价科技期刊的功能。结果 由于统计数据源不同,各引证指标数据库的引证指标数据差距较大。结论 用综合评价指标对期刊排名较单一指标排名能更准确反映期刊的学术水平和行业影响力;基于大型数据库的引证指标能更准确、全面地反映期刊被引用和传播情况,但基于源期刊的CSCD-JCR和CJCR引证指标更具有代表性,能更准确反映期刊的学术影响力和学科地位。
