Abstract：Alumni relationship significantly influences research output.Nevertheless,due to challenges in accessing educational background data,research on alumni relationship's impact on research output remains limited.Utilizing data from 30989 National Natural Science Foundation projects (2009—2014),we developed alumni centrality and research output metrics.Our findings revealed the followings.①Alumni relationship significantly and negatively impacts research output,with a more pronounced effect on ordinary papers than high-quality ones.Additionally,the adverse influence on technical efficiency outweighs that on scale efficiency,and direct alumni relationship have a more substantial impact than indirect ones.②The negative impact of alumni relationship on research output intensifies during a researcher's early career,in high-knowledge-barrier disciplines,and with affiliations to 985/211 universities or the Chinese Academy of Sciences.It's also stronger when papers are published in Chinese.③Alumni relationship negatively affects research output by bolstering a researcher's weak ties and shrinking project teams.Our research underscores alumni relationship's significance in scientific research and offers insights for optimizing research resource allocation in China.
