【摘要】：政策文件替代计量指标作为一种相对较新的指标,为测度学术成果的社会影响力提供了新方向,具有很高的研究价值。本文基于Altmetric.com公司从2013年1月到2016年6月收集到的所有政策文件替代计量指标数据9万余条,通过统计分析揭示其分布特征,旨在为进一步研究提供基础。研究发现,政策文件替代计量指标的相对覆盖率较低,为1.7%;相对引文指标没有及时性优势,平均时滞长达4.5年;论文层次的分布较为均匀,94%的学术成果仅有1条政策文件提及;期刊层次的分布基本遵循布拉德福定律,EFSA Journal等核心期刊是政策文件参考的主要学术成果来源;保健科学和医学是政策文件提及最多的学科,占据了"半边江山";具有政策文件替代计量指标的学术成果,其替代计量关注度指数总体处于中等偏上水平,没有明显优势。
[Abstract]:As a relatively new index, the policy document substitute measurement index provides a new direction for measuring the social influence of academic achievements. This paper is based on all the policy documents collected by Altmetric.com from January 2013 to June 2016 to replace the measurement data of more than 90,000. Through statistical analysis to reveal its distribution characteristics, in order to provide a basis for further research. The study found that the relative coverage of policy document alternative measurement index is relatively low, 1.7; Compared with the citation index, there is no advantage in timeliness and the average delay is 4.5 years. There is only one policy document about 94% of the academic achievements. The distribution of periodical level basically obeys Bradford's law. The core journals such as EFSA Journal are the main sources of academic achievements for reference of policy documents. Health science and medicine are the most mentioned disciplines in the policy document, accounting for "half of the river"; With the academic achievement of policy document substitution measurement index, its alternative measurement concern index is generally in the middle level, and there is no obvious advantage.
