摘要
本文以"开放牛津"的93种混合型期刊为研究样本,对其2009年刊载的全部论文的被引频次进行统计分析,以验证关于开放获取引用优势(OACA)的三个假设:存在开放获取引用优势;不同学科的OACA不同;OACA与期刊影响因子有相关性。通过研究发现:开放牛津期刊存在OACA,开放牛津期刊中的OA论文与非OA论文相比有138.87%的引用优势;五个学科领域的开放牛津期刊的OACA存在差异(其中人文科学不存在OACA);开放获取引用优势与期刊影响因子之间具有显著的逆函数关系,即随着期刊影响因子的增长,开放获取引用优势呈下降趋势。
This study takes 12354 original research articles published on 93 Oxford Open journals in 2009 as a sample,and then carries out statistic analyses on the citation frequency that these articles have received by July 2010 to validate 3 hypotheses:(1) there is citation advantage for open access articles(OACA) published in Oxford Open journals over the non-OA ones;(2) OACA varies with disciplines;(3) higher-impact-factor Oxford Open journals maybe have weaker OACA over lower-impact-factor ones.We finally discovers that: 1) there exists OACA for open access articles,in this case which indicates 138.87% over non-OA ones;2) different disciplines have different OACAs,and Humanities journals of Oxford Open have even a negative OACA;3) Oxford Open journals with lower IFs have stronger OACAs than those with higher IFs,namely OACA would shrink along with the augment of journals' IFs.
