Scientific collaboration plays a significant role in scientists' research performance. When scientists move from one institution to another and leave the team they belong to or lead, they may continue collaborating with the former team because engaging in or building a new team takes time. In this study, we collected data from the Open Researcher and Contributor ID (ORCID) website on 2,922 scientists who published first-tier journal papers defined by the Chinese Academy of Science (CAS) before they moved to a new institution. By applying a Poisson regression model to the dataset, we explored the correlation between continued collaboration and the transition period after scientists moved, which is defined as the time span between the year of the move and the year when they published their first top-tier journal paper after moving. Our findings indicated that: (1) continued collaboration significantly shortens the transition period by 27.2%; (2) continued collaboration significantly shortens the transition period of senior scientists to a larger extent than that of junior scientists; (3) continued collaboration significantly shortens the transition period of social scientists to a larger extent than that of natural scientists; (4) the transition period is shorter after moves for scientists with higher inherent potential; and (5) there is no evidence that the transition period is associated with culture-related differences between the origin country and the destination country after the move, or whether they had lived in the destination country before.
科研合作在科学家的研究表现中发挥着重要作用。当科学家从一个机构转到另一个机构,离开他们所属或领导的团队时,他们可能会继续与原团队合作,因为组建新团队需要时间。在本研究中,我们从开放研究者和贡献者标识符(ORCID)网站收集了2922名科学家的数据,这些科学家在转到新机构之前发表了中国科学院(CAS)定义的一流期刊论文。通过对数据集应用泊松回归模型,我们探讨了科学家迁移后持续合作与过渡期之间的相关性,过渡期定义为迁移年份与迁移后发表第一篇顶级期刊论文年份之间的时间跨度。我们的研究结果表明:(1)持续合作显著缩短过渡期27.2%;(2)持续合作对资深科学家过渡期的缩短幅度明显大于初级科学家;(3)持续合作对社会科学家过渡期的缩短幅度明显大于自然科学家;(4)内在潜力较高的科学家迁移后的过渡期较短;(5)没有证据表明迁移后的过渡期与迁移前后原籍国和目的地国之间与文化相关的差异有关,也与他们之前是否在目的地国生活过无关。
