考虑动态水权分配的差异化寡头垄断

Differentiated oligopoly considering dynamic water rights allocation

研究了一个商品具有差异化并且价格具有粘性的动态寡头对策模型。在生产规划和节水问题双重决策问题的基础上,提出水资源优化模型,给出了静态纳什均衡、反馈均衡下的最优生产规划、节水决策和购水决策,最后分析了寡头垄断竞争对社会福利的影响,并对参数值变化时的最优解进行了数值模拟。该研究认为初始水权分配是一个随时间变化的动态变量,政府可以根据企业节水、用水、购水情况的实时反馈对初始水权进行重新分配,避免水资源浪费。结果表明,初始水权分配和产品的初始保留价格、水权的初始保留价格之间是可以相互影响的,同时,企业的生产规划、节水规划和购水决策以及初始水权分配会受到产品的初始保留价格和水权的初始保留价格的影响。

This paper examines a dynamic oligopoly response model with differentiated goods and sticky prices.Based on the dual decision problem of production planning and water conservation,this paper propose a water resource optimisation model and provide optimal decisions on production planning,water conservation,and water procurement under static Nash equilibrium,open-loop Nash equilibrium,closed-loop Nash equilibrium,and feedback equilibrium.Finally,this paper examines the effects of oligopoly competition on social welfare,analysing the optimal solution by means of numerical simulation as parameter values change.In this paper,we contend that the initial allocation of water rights is a dynamic variable that varies over time and suggest that the government could adjust initial water rights based on real-time feedback from enterprises regarding water conservation,usage and procurement in order tOprevent water waste.The results show that the initial water right allocation,the initial reserve price of the product and the initial reserve price of the water right can interact with each other.Meanwhile,the production planning,water conservation planning,water purchase decision and initial water right allocation of the firm are affected by the initial reserve price of the product and the initial reserve price of the water right.
