摘 要: 以"理性人"假设为基础的期望效用理论指导风险评估时忽略了企业自身应对风险的能力,在一定程度上会影响后续风险管理工作的科学性与有效性。根据问卷调查获取的数据,分析了项目管理者风险应对能力、基于期望效用的风险重要性指数及风险管理投入努力度三者之间的关系。研究结果表明:基于期望效用理论的风险重要性排序与管理者相应的风险应对能力排序之间存在显著差异,管理团队的风险应对能力与其针对风险的管理投入之间具有更强的正相关关系。并建议在现有风险评估体系中增加项目管理者风险应对能力这一指标。 The expected utility theory ignores the company's own ability to deal with risk with the hypothesis of rational man which affects the effectiveness and scientificity of risk management to some certain extent. Based on a questionnaire survey, this paper analyzes the relationship among the project management team's risk response ability, risk assessment based on the expected utility and managerial input. The result shows that the risk rank based on the expected utility theory has a significance discrepancy with the corresponding response capacity of risk management team, and there is a stronger positive correlation between risk management team's response capacity and managerial input of risk factors. Suggestions are presented for better risk management in the construction industry.
