基于生活质量指数的风险社会可接受性研究

风险的社会可接受性是风险管理的重要环节,文章从社会公众的角度出发,将风险可接受性看成一个社会事件,基于社会核心指标:人均国民生产总值GDP,人的寿命期望以及人们用来享受健康生活的时间,给出了生活质量指数的概念。利用该指数,结合净收益原则可以确定社会对于安全投入的支付意愿值,即,给出了一个定量的费用支出水平,超过该水平的安全投入就是不合理的。该方法可为评估风险减缓措施的有效性提供依据。

Social risk acceptability based on life quality index

Safety is an important objective in society but it is not the only one.The allocation of society's resources devoted to safety must be continually appraised in light of competing needs,because there is a limit on the resources that can be expended to extend life The paper presents the Life Quality Index(LQI)as a tool to quantify the level of expenditure beyond which it is no longer justifiable to spend resources in the name of safety.It is shown that the LQI is a compound social indicator comprising societal wealth and longevity,The paper provides an intuitive formulation of the LQI as equivalent to a valid utility function that is consistent with the principles of rational decision analysis.The paper concludes that the LQI can be promising in supporting decisions for risk management.
