学术合作是学术谱系内知识传承的核心特征,其合作关系和合作强度影响着谱系的发展和演变。文章运用社会网络分析以及历史学方法对以地质学家刘东生为核心的第四纪学术谱系的合作网络特征、学术传承进行分析,结果显示学术谱系内的合作是合作的主体,盘踞学术大本营的学生与导师的合作长期稳定,合作强度明显高于离开学术大本营到其他单位工作的学生。另外,研究显示刘东生通过选派学生去国外一流研究机构学习或合作研究,建立深入稳定的国际合作,促使了一批高水平研究成果的产生,从而提升了整个学术谱系的学术影响力。
Academic cooperation is the core feature of the inheritance of knowledge in academic pedigree. The cooperation and intensity of cooperation affect the development and evolution of pedigree. The article uses social network analysis and historical methods to analyze the characteristics of the cooperation network and the academic inheritance of Quaternary pedigree based on the geologist Liu Dongsheng. The results show that the cooperation within the academic pedigree is the main body of the cooperation and the students who occupy the academic base camp The cooperation with mentors is stable in long term, and the intensity of cooperation is obviously higher than that of students who left the academic camp to work for other units. In addition, the study shows that Liu Dongsheng promoted the academic influence of the entire academic pedigree by selecting students to study or cooperate with top-tier research institutions in foreign countries to establish in-depth and steady international cooperation, prompting a batch of high-level research results.
