摘　　要：耕地资源非市场价值评估既是福利经济学研究的热点,又是资源管理政策制定的依据。本文以张掖市甘州区的耕地保护规划为契机,基于选择实验详述了非市场价值评估中指标选取过程和实验设计方法,使用Mixed Logit模型和经验仿真方法分析了城镇居民和农村居民消费者剩余的变动。结果表明,耕地保护政策实施后,甘州区城镇居民的平均补偿剩余为3445.79元/户,农村居民的平均补偿剩余为3263.19元/户,社会福利整体增加5.09亿元;城镇和农村居民组内对价值评估指标的偏好存在显著的随机性,组间对耕地生态系统服务的支付意愿存在显著的异质性。Welfare Economics has generated an abundance of non-market valuation methods to help inform farmland protection policies. Choice experiment,based on public preference,is often employed for such valuation for understanding the benefits associated with different policy outcomes. Drawing from a case study of farmland conservation program in Zhangye Ganzhou district,this paper elaborates the formation of choice attributes and experimental design through the development of choice experiment questionnaire. Mixed logit model together with empirical simulation is used to measure urban and rural residents' welfare change separately. We conclude that: 1) the average urban residents in Ganzhou district are willing to pay 3445. 79 Yuan per household,compared with rural residents' 3263. 19 Yuan for the implementation of farmland conservation policy,and the average total welfare improvement will be 590 million Yuan; 2) urban and rural residents' preference for choice attributes varies within groups,and their estimated willingness to pay shows significant heterogeneous across groups.
