| 中文摘要: |
| S计划是重要的公共资助开放获取（OA）政策，在世界范围具有示范效应。本文以S计划转换期刊（TJ）项目为例，分析OA资助政策对期刊学术影响力的提升效应，揭示OA促进科学知识传播的作用，为国内相关政策制定提供借鉴。基于2014—2023年Scopus数据库期刊数据，采用双重差分法分析加入TJ项目前后混合OA期刊的篇均被引频次差异，探讨OA论文占比的中介作用。研究发现：TJ项目显著提升混合OA期刊的篇均被引频次；在OA论文占比提升达到TJ项目要求的条件下，OA论文占比在TJ项目对篇均被引频次的影响中起部分中介作用。异质性分析表明，TJ项目对于不同地区、学科、出版社期刊篇均被引频次的影响存在差异。我国可借鉴其实践经验，从引导方式、实施规范和组织模式等方面改革OA资助政策，推动OA运动可持续发展。 |
| 英文摘要: |
| Plan S is an important open access (OA) policy driven by public funding, which has formed a demonstration effect in the world. Taking the transformative journal (TJ) programme proposed by Plan S as an example, this paper analyzes the role of OA funding policies in enhancing the academic influence of journals, explores how OA promotes the dissemination of scientific knowledge, and provides references for the formulation of relevant policies in China. Based on the journal data from the Scopus database spanning 2014 to 2023, the difference-in-difference method is used to analyze the difference in citations per article between the journals before and after joining the TJ programme, and to analyze the mediating effect of the proportion of OA articles. Results indicate that hybrid OA journals experience a significant increase in average citations per article after joining the TJ programme. Under the condition that the proportion enhancement of OA articles meets the requirements of TJ programme, the proportion of OA articles plays a partial mediating role in the effect of the TJ programme on the average citations per article. Heterogeneity analysis indicates that the TJ programme exhibits different influences across region, subject,and publisher. China can learn from its practical experience and reform the OA funding policy in terms of guidance methods, implementation standards, and organizational models to promote the sustainable development of the OA movement. |
