资源型城市居民改善空气质量的支付意愿——以山西太原为例

The Resident’s Willingness to Pay for Air Quality Improvement in Resource-based Cities:Taking Taiyuan City of Shanxi Province as an example

研究资源型城市居民对空气质量改善的支付意愿及影响因素,有利于进一步推动各地区实行减污降碳。基于山西太原443份调研问卷,利用条件价值评估法测算居民的支付意愿及支付额度,构建二元Logistic回归模型和Tobit模型对支付意愿及支付额度的影响因素进行分析。发现79.2%的受访者具有正的支付意愿,平均支付意愿为28.16元/(月·人),其中受教育程度、家庭总收入、是否患有呼吸系统疾病、本地居住时长、是否关注空气质量以及空气质量对健康危害程度具有显著的正向影响,而性别、年龄、职业、居住位置、对空气质量的现状满意度以及对政府采取措施的满意度影响不显著。为此,应加强环保宣传教育,合理制定支付标准,制定相应的实施政策,以引导居民支付空气质量改善的费用。
