In recent years, China has placed high importance on strengthening and standardizing the management of scientific data. In 2018, the General Office of the State Council issued the Measures for the Management of Scientific Data, requiring mandatory deposit of data generated from government-funded science and technology projects at all levels, and proposing the establishment of a sound management system for data deposit associated with domestic and international academic papers. This study investigates the current perceptions of sci-tech journal editors in Shanghai regarding the deposit of associated data for research papers, identifies and analyzes their cognitive characteristics, and provides references for advancing and refining data deposit practice in China.The study employs a questionnaire survey method to investigate frontline full-time editors from sci-tech journal publishers in Shanghai. The survey focuses on journal editors' cognition of data sharing and deposit of associated data for research papers, covering three main areas: awareness of relevant concepts, policies, and ideas; understanding of technical procedures in the data deposit process; and knowledge of scientific data repositories and collaboration. Based on the survey results, the study analyzed and summarized the distinctive features of editors' perceptions, and offers recommendations for journal publishers to promote and implement associated data deposit and sharing.

The findings reveal the following characteristics of Shanghai sci-tech journal editors' perceptions of associated data deposit: ① They possess a relatively strong foundational awareness of data ownership and management; however, this high level of industry awareness is disconnected from current practices of journals. ②Although respondents generally acknowledge the necessity of conducting data review for associated papers, there remain cognitive deviations regarding the responsible entity for data review. ③ Their understanding of the importance of localized data storage remains to be improved. Many editors hold misconceptions about the relationship between "journal internationalization" and "storage localization", tending to assume that journal internationalization implies that associated data must also be stored "internationally".

Based on the analysis, the paper proposes the following recommendations for journal publishers to advance and implement associated data deposit and sharing: ① strengthen policy dissemination and professional training; ② deepen collaboration with data repository platforms; ③ develop data deposit management tools by leveraging clustered journal publishing platforms.
