Abstract

The value of statistical life (VSL) reflects the trade-off between money and the risk of death. It is a key indicator for conducting regulatory impact assessments. The main purpose of this study was to estimate the VSL in the field of food safety. At the same time, it investigates respondents' willingness to pay (WTP) for reducing the risk of death from foodborne illnesses and explores the impact of factors such as the average household monthly income, health status, and education level on WTP. We conducted a survey using an open-ended contingent valuation method among 1307 respondents aged 18 and above to determine their WTP. Based on the WTP survey results, we calculated the VSL in the food safety sector. We used binary logit and Tobit models to analyze the influencing factors. The results of the study show that the median WTP for reducing the risk of foodborne illness is CNY 100 (USD 16), and the estimated VSL is approximately CNY 9.09 million (USD 141 million). Indicators such as the average household monthly income, health status, and education level are important factors affecting WTP. This study will help practitioners, researchers, and policymakers understand the current population's attitudes towards food safety regulations and determine the priorities for regulatory implementation. Future research can explore the effects of different elicitation methods, cultural differences, and regional variations on WTP and VSL.

摘要

统计生命价值(VSL)反映了金钱与死亡风险之间的权衡。它是进行监管影响评估的关键指标。本研究的主要目的是估计食品安全领域的统计生命价值。同时,调查受访者为降低食源性疾病死亡风险的支付意愿(WTP),并探讨家庭月平均收入、健康状况和教育水平等因素对支付意愿的影响。我们采用开放式条件价值评估法对1307名18岁及以上的受访者进行了调查,以确定他们的支付意愿。基于支付意愿调查结果,我们计算了食品安全领域的统计生命价值。我们使用二元logit模型和Tobit模型分析影响因素。研究结果表明,降低食源性疾病风险的支付意愿中位数为100元人民币(16美元),估计的统计生命价值约为909万元人民币(1.41亿美元)。家庭月平均收入、健康状况和教育水平等指标是影响支付意愿的重要因素。本研究将有助于从业者、研究人员和政策制定者了解当前民众对食品安全法规的态度,并确定监管实施的重点。未来的研究可以探讨不同诱导方法、文化差异和地区差异对支付意愿和统计生命价值的影响。
