摘　　要：条件价值评估方法是生态产品价值核算的基本方法,但在实践中存在一些误区。文章基于福利经济学的研究方法,针对利用条件价值评估方法评估生态产品的社会价值中碰到的一些现实问题加以梳理,认为:生态产品的社会效益本就包涵经济效益,二者之间不存在此消彼长的关系;生态产品项目的价值评估实质上就是评估其社会净效益;由于多数项目既存在得益者,也存在受害者,因此生态产品项目的价值评估既要针对得益者使用支付意愿指标,也要针对受损者使用受偿意愿指标,并且这两个指标的权重应该均等,而不应有所偏颇;生态产品项目的支付意愿曲线等价于微观经济学中的市场需求曲线,但不同于计量经济学中的市场需求曲线。Contingent valuation method is a basic method for accounting the ecological product value,but in practice there exist some mistaken ideas about it. Based on the research methods in welfare economics,this paper teases out the practical problems encountered in evaluating the social value of ecological products and concludes that the economic benefits of ecological products contain economic efficiency,so the evaluation of ecological product items is essentially an assessment of their social net benefits; that the evaluation of ecological product items should be aimed at both beneficiary＇s pay willingness index and loser＇s repayment willingness index with the weight of these two indicators equal and balanced; and that the pay willingness curve is equivalent to the market demand curve in micro- economics but different from the market demand curve in econometrics.
