基于CVM的农户水价支付意愿及其影响因素分析——以张掖市甘临高三地为例

科学合理的水价制度有助于促进水资源的可持续利用。农户作为农业灌溉用水的主体,在制定与实施水价政策的过程中必须考虑他们对水价的态度和承受能力。文中以黑河流域张掖市甘州区、临泽县和高台县为例,设计问卷实地调查获取数据,利用条件估值法(CVM)评估了农户对农业灌溉用水水价的支付意愿,通过列联表方法分析了支付意愿的影响因素。结果表明:1)农户的水价平均支付意愿为75.37元·亩-1;2)影响因素分析中,支付意愿与总播种面积、玉米播种面积、灌溉用水类型、家庭总收入、家庭主要劳动力年龄、个体风险认知和所在区域7个因素显著相关(Approx.Sig<0.05);与灌溉方式存在较明显的相关关系(Approx.Sig<0.1)。研究结果证明,运用CVM评价农户对农业水价的承受能力具有一定实践意义,可为水价改革制度的制定和实施提供借鉴。

Economic Value of Water Resources of the Upper Reaches of the Xin’an River Basin, China

Estimating the value of water resources not only forms the basis of water rights transactions between upstream and downstream and eco-compensation standards, but also provides scientific data for the reasonable establishment of local water prices and promotes sustainable use and efficient management. Here, we estimate the economic value of the water resources of the upper reaches of the Xin’an River basin. Our purpose is to establish theoretical support for eco-compensation standardization and provide data for the protection of water resources and water price reform.
