[目的/意义] 数据出版与科技期刊融合发展是一条“双赢”之路。针对目前期刊论文关联数据出版量少，论文作者数据出版的意识和积极性还没有被充分激发出来等问题，调研国际出版商数据政策的实践经验，在此基础上提出我国科技期刊参与数据出版的机制和政策，为推动我国数据出版、建设世界一流期刊提供有力支撑。[方法/过程] 通过文献综述、案例分析、网站信息采集等方法分析我国数据与论文关联出版现状及Elsevier、Springer Nature、Wiley、SAGE Publishing和Taylor & Francis五大国际出版商的数据政策及运行机制。[结果/结论] 五大出版商实施数据政策的模式基本一致：整体政策说明+旗下期刊自由选择。Elsevier、Springer Nature、Wiley、SAGE Publishing和Taylor & Francis旗下分别有68%、99.9%、92.2%、47.0%和69.3%的期刊明确提出数据政策，但以鼓励为主。我国出版界可以借鉴国际出版商的实践经验，结合我国科技期刊的特点，制定科技期刊数据政策标准规范和实施模式，由少到多、由点到面逐步推动数据出版与科技期刊在广度和深度上融合发展。

[Purposes/significance] Integrative development of data publication and sci-tech journals is a win-win solution. However, nowadays the publication of data related to journal articles is few and the awareness and initiative of authors about data publication have not been activated yet in China. Therefore, this paper investigated practical experience for data policies of international publishers, on this basis, the operation mechanism and data policies which suitable for sci-tech journals in China were put forward, as to provide strong support for data publication and world-class journal construction in China. [Methods/process] The data policy and operation mechanism of five international publishers (i.e., Elsevier, Springer Nature, Wiley, SAGE publishing, Taylor & Francis and so on) and the current situation of the publication of data related to journal articles in China were obtained through literature research, case research, and network information collection. [Result/conclusion] The implementation mode on data policies of five international publishers is basically same: general policy introduction + free choice of individual journals. Results showed that 68%, 99.9%, 92.2%, 47.0% and 69.3% of journals under Elsevier, Springer nature, Wiley, SAGE publishing, and Taylor & Francis clearly put forward the data policies, respectively. However, most of them adopted the “encouragement” policy. Their practical experience for data policies is worth learning for Chinese journals. Based on characteristics of Chinese journals, we should formulate the journal data policy standards and implementation mode, gradually promoting the breadth and depth of the integrative development of data publication and sci-tech journals.
