国内生物医学类开放获取期刊在学术交流中的影响力研究

Influence of open access journals of biomedicine in China on academic exchanges

目的以中国科学引文数据核心库（CSCD—C）收录的生物医学期刊为数据来源，通过实证分析，对开放获取期刊在学术交流体系中的影响力进行比较研究。方法采用文献计量学与统计学方法，利用SPSS软件进行秩和检验，对CSCD收录的开放获取与非开放获取的生物医学期刊分别进行多指标统计。结果开放获取期刊仅占统计期刊总数的31．63％；开放获取期刊平均基金论文比为72．29％。统计期刊在学科中的影响力，临床医学与特种医学类开放获取期刊的自被引率较高；生物学类开放获取期刊的平均影响因子与h指数较高；预防医学类开放获取期刊的平均影响因子较高；综合医学类非开放获取期刊的平均h指数较高。结论各学科开放获取期刊的数量分布不均衡；开放获取期刊的基金论文比高于非开放获取期刊，两者学科影响力差异不明显。

Objective To compare the influence of open access journals （OAJ） of biomedi- cine on academic exchanges by empirically analyzing the journals enrolled in the Chinese science cita- tion database-the core （CSCD-C）. Methods Multivariate statistical analysis was performed on OAJ and non OAJ in CSCD by using bibliometric and statistical methods, SPSS software and rank-sum test. Results The OAJ were accounted for only 31.63% of the total enrolled journals, the average ratio of funded papers in OAJ was 72.29%. Statistical journals had high influence in the discipline. The self- citation rates of clinical medicine OAJ and special medical OAJ were high. The average impact factor and h index in biological OAJ were high. The average impact factor of preventive medicine OAJ was high. The average h index of comprehensive non OAJ was high. Conclusions The distribution of OAJ is uneven among different disciplines. The ratio of funded papers is higher in OAJ than in non OAJ with insignificant differences in discipline influence.
