| 中文摘要: |
| 采集较大样本量,并引入虚拟变量代表样本期刊是否独家出版,运用相关和回归分析观察独家出版对科技期刊影响因子的影响。相关分析表明,无论是CNKI还是万方独家出版,影响因子与是否独家出版之间均存在显著的负相关性。对包含CNKI独家期刊的数据回归分析显示,虚拟变量前的回归系数虽然为负值但从统计学上看并不显著。对包含万方独家出版的医学期刊的数据回归分析发现,虚拟变量前的系数不仅为负值,而且具有统计学上的显著性,表明万方独家出版引起期刊影响因子降低。结果还显示,若独家出版对影响因子有影响,将非常显著。期刊应慎重考虑是否独家出版。 |
| 英文摘要: |
| In order to explore the effects of exclusive digital publishing on impact factor of journals, we analyze large samples with correlation and regression analysis. Dummy variables are introduced into the analysis which represent whether a sample journal is exclusive or not. Correlation analyses show that there are remarkable negative correlations between impact factor and exclusive publishing no matter which publisher (CNKI or Wanfang) publish them. When using the journals exclusively published by CNKI, the regression analyses show that the regression coefficients of dummy variables are negative but not statistically significant. When using the journals exclusively published by Wanfang, the regression analyses show that the regression coefficients are both negative and statistically significant, which suggests that exclusive publishing causes decrease of impact factors. The analysis results also show that if exclusive publishing has negative effects on impact factor, the effects will be very marked from statistics view. Therefore, journals should carefully consider whether to be exclusively published or not. |
