目的运用德尔菲法对PI制科研管理模式的影响因素进行分析,初步确定影响PI制科研管理模式的相关因素。方法采用德尔菲法问卷咨询法。结果两轮问卷调查,专家积极系数都为100%,专家权威系数分别为0.80和0.84。第一轮的变异系数为0.11,肯德尔和谐系数为0.78;第二轮变异系数为0.04,肯德尔变异系数为0.89,且两次的检验差异都有统计学意义（P〈0.01）。PI制管理模式影响因素的重要程度依次为PI自主权、稳定的科研经费来源、科研机构学术氛围。结论通过德尔菲法评价影响PI制科研管理相关影响因素,为PI制的高效率科研管理提供参考和帮助。Objective To evaluate and determine the factors affecting Principal Investigators（PI） research management mode by Delphi method.Methods Expert consultation was conducted in the form of questionnaire according to Delphi method.Results The positive coefficients of two rounds of expert consultation were both 100% and the authority coefficient was 0.80 and 0.84 in the two rounds.In the first round,coefficient of variation were 0.11 and coordination coefficient（Kendall W） was 0.78.In the second round,coefficient of variation was 0.04 and coordination coefficient（Kendall W） was 0.89,and the differences of the two rounds were statistically significant（P 0.001）.The factors affecting PI management mode was PI autonomy,stable source of research funding and academic environment in order of sigificance.Conclusion Evaluation of key factors by Delphi method can provide reference for more effective PI research management
