摘要
基于影子价格方法建立两阶段水权交易均衡价格测算模型。第一阶段为单边测算阶段,对转让方、受让方分别构建影子价格模型。以各部门用水边际收益最大为目标,基于用水投入产出平衡关系构建转让方影子价格模型;以各部门用水净效益最大为目标,基于各部门用水上下限和总供水量等建立受让方影子价格模型,利用Lingo测算双方各用水部门影子价格。第二阶段为双边耦合测算阶段,以国民经济整体效益最大为目标,将第一阶段测算的双方影子价格,结合微分博弈均衡理论,运用HJB条件确定均衡水价。最后结合中国首批水权交易试点地区甘肃、内蒙古进行算例研究,并提出政策建议。
Based on the shadow price method,a two-stage water right trade equilibrium price measurement model is established.The first stage is the unilateral measurement stage.The shadow price model is built for the transferor and the transferee respectively.Taking the maximum marginal revenue of water use of each department as the target,the shadow price model of transferor is constructed based on the equilibrium relation of water input and output.Aiming at the maximum net benefit of each department,the shadow price model of the transferee is established based on the upper and lower limits of each department’s water consumption and the total water supply,etc.Lingo is used to calculate the shadow price of each water sector on both sides.The second stage is the bilaterally coupled calculation stage.Aiming at the maximum overall benefit of the national economy,the shadow price calculated in the first stage is combined with the equilibrium theory of differential game,and the HJB condition is used to determine the equilibrium water price.Finally,the case study of Gansu and Inner Mongolia in China’s first water rights trading pilot areas is carried out,and policy suggestions are put forward.
