基于履历信息的海外华人高层次人才成长研究:生存风险视角

Using the Curriculum Vitae for Career Trajectories Research of Top Chinese Overseas Talents:the Perspective of Survival Hazard Analysis

本文从ESI高被引作者库中的华人科学家入手,通过网络搜集到其中233名科学家的履历信息,对其进行深度加工,利用Kaplan-Meier法研究了不同因素下各阶段生存风险率的差异,并用Cox比例风险模型探讨了成长过程中各因子的具体影响效果。KM结果表明在职业生涯的初级阶段获得博士学位的国别对科技人才的职业成长具有显著影响,在美国获得博士学位或不在中国获得博士学位的科技人才都具有相对明显的优势实现快速成长;在较高级阶段这种影响越来越不显著。Cox结果表明博士毕业后选择在研究所工作增加了助教和教授阶段的生存风险,从而加速职业成长;而具有博士后工作经历则降低了助教和教授阶段的生存风险,从而减缓了成长速度。

The paper has presented detailed information about how to proceed with a survival analysis of career trajecto-ries research of Chiuese overseas highly-talents from CVs. Using Cox proportional hazard model,it revealed the effects of different situations after obtained PhD on the survival rates. Specifically, talents received PhD in US spent less time be- coming assistant professor,but rather associate professor and professor. Those who worked in research institutions after the Doctor graduation require less time becoming assistant professor and professor. Furthermore, the postdoctoral experi-encing has a negative effect on being assistant professor and professor.
