摘要：

目的 从定量角度探讨期刊实施科研数据开放政策对期刊学术影响力的提升效应，从而推动期刊学术影响力不断提升并为期刊制定相关科研数据开放政策提供理论依据和决策参考。 方法 以中国科学引文数据库（CSCD）收录的中文期刊为研究对象，首先调查期刊科研数据开放政策的实施情况，随后采用双重差分法（DID）评估科研数据开放政策对期刊学术影响力的政策效应，并通过多种稳健性检验及异质性分析进一步验证结果的可靠性。 结果 科研数据开放政策的实施能够显著提升期刊的学术影响力，且政策效应在不同属性的期刊中表现出显著的异质性。 结论 期刊通过制定并执行科研数据开放政策，不仅能够提高研究论文的透明度和可靠性，还能增强期刊的学术声誉，从而扩大其学术影响力和社会影响。

Abstract:

Purposes The purpose of this paper is to explore the effect of implementing open research data policies on the enhancement of journal academic influence from a quantitative perspective， thereby promoting the continuous improvement of journal academic impact and providing a theoretical basis and decision-making reference for journals in formulating related open research data policies. Methods The study focuses on Chinese journals indexed in the Chinese Science Citation Database （CSCD）. It first investigates the implementation status of open research data policies in these journals. Then， the difference-in-differences （DID） method is used to assess the policy effects of open research data on the academic influence of journals. Various robustness tests and heterogeneity analyses are conducted to further validate the reliability of the results. Findings The implementation of open research data policies significantly enhances the academic influence of journals， with policy effects showing significant heterogeneity across journals with different attributes. Conclusions By formulating and implementing open research data policies， journals can not only improve the transparency and reliability of research papers but also enhance their academic reputation， thereby expanding their academic influence and societal impact.
