基于选择试验法的北京市城乡居民耕地保护支付意愿研究

A Study on Willingness of Urban and Rural Residents to Pay for Cultivated Land Preservation Based on Choice Experiment Method

[目的]测算北京市城乡居民耕地保护的支付意愿,检验二者的支付意愿差异,并分析差异形成的原因,为制定面向对象差异化的耕地保护政策提供理论借鉴。[方法]采用选择试验法(CE),R统计及部分经济学模型。[结果]农村居民对保护耕地面积、耕地质量和耕地景观生态环境的支付意愿分别为67.24,113.75,51.47元/a,而城镇居民的支付意愿分别为58.07,66.40,150.80元/a。[结论]城镇居民的支付意愿明显高于农村居民,个体支付意愿与其文化程度、家庭年总收入、家庭抚养人口数显著相关;从二者耕地功能需求的角度看,城乡居民对耕地各项功能需求最高的分别为生态功能与生产功能,在需求差异的驱动下样本在选择集中做出符合自己需求偏好的选择。
