摘　　要：【目的/意义】信息不确定的情况下信息瀑布现象层出不穷,现有信息瀑布研究主要是针对群体一致性行为。本文基于信息瀑布理论、个体决策理论和调节定向理论,重在探究不同准确度的环境信息对信息瀑布中个人决策行为的影响。为信息瀑布的管控提供理论思路。【方法/过程】本文基于相关理论构建了环境信息对信息瀑布中个人决策的影响模型,通过调查问卷的方法采集个体的样本信息,并通过相关分析、回归分析、方差分析的方法对提出的假设进行了验证。【结果/结论】结果表明,环境信息准确度正向影响信息瀑布中个人决策行为,而私人信息可信度反向影响个人决策行为;私人信息在环境信息与决策行为间具有中介效应;相比预防定向,促进定向在环境信息与决策行为间的调节作用更显著。【创新/局限】本文基于个体层面的研究丰富了信息瀑布和调节定向的相关理论研究,但尚未考虑个体的其他特质因素的影响。【Purpose/significance】Information cascades emerge one after another under the condition of uncertain information.The existing information cascades research is mainly focused on the group consistent behavior.Based on information cascade theory,individual decision-making theory and regulatory focus theory,this paper focuses on the influence of environmental information with different accuracy on individual decision-making behavior,in information cascade.It provides the theoretical thinking for the management and control of the information cascade.【Method/process】Based on relevant theories,this paper constructs a model of the influence of environmental information on individual decision-making in an information cascade,the proposed hypothesis is verified by correlation analysis,regression analysis and variance analysis.【Result/conclusion】The results showed that the accuracy of environmental information positively affected individual decision-making behavior in information cascade,while the credibility of private information negatively affected individual decision-making behavior.Private information has a mediating effect between environmental information and decision-making behavior.Compared with prevention orientation,promotion orientation has a more significant moderating effect on environmental information and decision-making behavior.【Innovation/limitation】The research based on the individual level enriches the related theory of information cascade and regulatory focus,but it has not considered the influence of other characteristic factors of individual.
