基于选择实验法的流域中下游居民生态补偿支付意愿及其偏好研究——以渭河流域为例

在流域生态补偿机制的建设中,相关利益主体的生态补偿意愿和行为的分析对政策的管理和执行至关重要。运用选择实验法对渭河流域中下游居民的支付意愿进行考察,通过构建Mixed Logit模型对城乡居民的支付意愿及其偏好进行实证分析。研究发现,城镇和农村居民的选择显著受到水质、河流面积/水量、水土流失情况、动物种类/数量这4个属性变量的正向影响,支付金额的负向影响;其次,城镇和农村居民对水质这一属性具有最高的支付意愿,对河流面积/水量这一属性具有次高的支付意愿,而对动物种类/数量这一属性具有最低的支付意愿;最后,城镇和农村居民的平均支付意愿分别为13.168元月^-1人^-1和9.050元月^-1人^-1,前者的支付意愿明显高于后者。

Study on willingness to pay and preference of ecological compensation for residents in the midstream and downstream of the Weihe watershed based on choice experiment method

In the establishment of watershed ecological compensation mechanism, the willingness and behavior of ecological compensation of relevant stakeholders is essential to the management and execution of policies. This article uses choice experiment to examine the willingness to pay (WTP) of the residents in the midstream and downstream of of Weihe watershed. We empirically analyzed the WTP of urban and rural residents and the respondents'' preferences by the Mixed Logit model. The results showed that the choice of urban and rural residents was positively affected by water quality, river area/water, soil and water loss situation, and the animal species/quantity, while negatively affected by payments. Secondly, the urban and rural residents had the highest willingness to pay for the property of water quality, the second highest willingness to pay for the property of river area/water volume, and the lowest willingness to pay for the property of animal species/number. Finally, the average WTP of the urban and rural residents was respectively 13.168 yuan/month/ person and 9.050 yuan/month/person. The former WTP was significantly higher than the latter.
