虚拟水战略为众多国家和地区面临的水资源分布不均问题提供了可行解决方案,但其具体落实涉及的合作博弈机制还有待深入研究.文中基于委托-代理模型和沙普利值模型,综合考虑实施虚拟水战略的各区域以及上级政府之间的利益协调分配机制,并通过数值模拟验证该利益分配机制的科学性.研究发现,在合作博弈视角下,利用改进的沙普利值模型设计各区域之间的利益分配方式,并将其融入上级政府与区域之间的利益分配契约中,由此设计出的利益分配机制科学且合理.1)上级政府可以充分地激励更多区域联盟实施虚拟水战略,从而实现收益最大化.2)沙普利值的分配方式统筹兼顾了效率与公平,不仅能扩大实施虚拟水战略的区域联盟的规模,还能实现联盟整体收益最大化,有利于高效解决区域间水资源分布不均衡及供需矛盾问题.
Coordination mechanism in virtual water strategy:Cooperative game
Virtual water strategy(VWS)provides a feasible solution for the uneven distribution of water resources in many countries and regions.However,the implementation of VWS involves a cooperative game mechanism that needs further study.Based on the principal-agent model and Shapley value model,this study proposes a benefit distribution mechanism of the cooperative game including the regions where the VWS is implemented and their superior government,and verifies the rationality and feasibility of the mechanism through numerical simulation.The results show that the benefit distribution mechanism in cooperative game is conducive to the smooth implementation of the virtual water strategy,which fully takes the interests of the superior government and various regions into account.On one hand,the cooperative game mechanism can help the superior government encouraging more regions to join the alliance to implement VWS,thereby maximizing its benefits.On the other hand,the distribution model guided by Shapley value integrates efficiency and fairness,which can not only expand the scale of regional alliances of VWS,but also maximize the overall utility of the entire society.This study proves that the cooperative game theory is conducive to efficiently improve the uneven distribution of water resources and the imbalance between supply and demand of virtual water.
