六大国际检索系统收录我国科技期刊的循证研究

Evidence-Based Research on Chinese Academic Journals Inde xed by Six International Index Systems

目的研究我国科技期刊被6大国际检索系统收录情况,以期为我国科技期刊健康有序发展提供科学依据.方法应用循证医学原理和方法,通过网络搜索和数据库检索SCI等6大检索系统对我国科技期刊的收录信息,尤其是教育部主管的科技期刊,由6名训练合格的评价员盲法评价所得信息.结果截至2004年8月,SCI共收录我国科技期刊76种,占我国科技期刊总数的1.52%,其中教育部主管科技期刊6种,占教育部主管科技期刊的1.46%;我国被ISI收录的科技论文的平均影响因子在0.9～2.2之间,平均被引次数(相对影响力)在0.2～0.5之间;约有4.8%、1.6%、1.28%和11.32%的科技期刊分别被美国<工程索引>(EI)、美国<医学索引>(IM)、荷兰医学文摘(EM)和俄罗斯文摘(AJ)收录.结论我国科技期刊被重要检索系统收录数量偏少,质量也有待提高.

Objective To investigate the academic journals indexed by 6 international index systems so as to provide scientific evidence for the development of acad emic journals.Methods The principle and approach of evidence-based medicine were adopted. Information about Chinese academic journals indexed by 6 index systems was obtained by WEB searching and database retrieval. Details of academic journals in the charge of the Ministry o f Education of China( MOE) were sought and assessed by six well-trained reviewe rs using a blind method. Results Seventy-six a cademic journals were indexed by SCI which was about 1.52% of total journals pu blished in China and six of them were in the charge of MOE (about 1.46% of the total). Citation impact of academic papers indexed by ISI ranged from 0.9 to 2 .2, and average impact ranged from 0.2 to 0.5. Approximately 4.8%, 1.6%, 1.28% and 11.32% academic journals were indexed by EI, IM, EM, AJ respectively . Conclusions The number of Chinese academic j ournals indexed by key international index systems was small, and the quality of journals should be greatly improved in future.
