空气污染是一个重要的全球性问题，各国政府都在努力减少空气污染物的排放。详细计算空气污染的社会成本，对于证明在空气污染控制政策上投入大量公共开支是必要的。本研究旨在通过市民的支付意愿（WTP），得出减少不同种类空气污染物的货币价值。通过选择实验调查，考察公众对空气质量改善的看法，并使用层次贝叶斯逻辑模型对收集到的陈述偏好数据进行分析。分析结果表明，公众对个别污染物减排的评价存在差异。平均来看，一吨减排的货币价值依次为PM2.5、PM10、SOx、TSP、NOx和VOC。根据所得WTP，对韩国政府的两项空气污染物减排计划的经济可行性进行了评估。根据平均WTP，这些计划的效益成本比分别为0.61和0.66，这表明它们目前在经济上是不可行的。根据研究结果，提供了有效分配空气污染控制政策预算的启示。
Air pollution is an important global issue, and governments are making efforts to reduce air pollutant emissions. The elaborate calculation of the social costs of air pollution is essential for justifying the substantial public expenditure on air pollution control policies. This study aims to derive the monetary value of reducing different kinds of air pollutants through the public's willingness to pay (WTP). A choice experiment survey is conducted to examine the public perception of air quality improvement, and the collected stated preference data are analysed with the hierarchical Bayesian logit model. The analysis results show that the public valuation of the emission reduction differs for individual pollutants. On average, the monetary value of one ton of emission reduction follows the order of PM2.5, PM10, SOx, TSP, NOx, and VOC. Based on the elicited WTP, the economic feasibility of the two air pollutant reduction plans of the South Korean Government is assessed. The benefit-to-cost ratio of the plans is 0.61 and 0.66, respectively, based on the mean WTP, indicating that they are not economically feasible at the moment. Implications for the efficient budget allocation of air pollution control policies are provided based on the results.
