摘要
为解决洪水时期流域上下游、左右岸区域主体之间争相排水的问题,亟须构建"准市场"下的排水权交易制度。立足于我国区域间防洪排水问题,提出排水权的概念,设计"准市场"下排水权交易制度框架及运行机制,通过构建区域间排水权交易的演化博弈模型,探讨影响区域间排水权交易的影响因素,最后利用Matlab软件进行仿真研究,分析各影响因素的变化对交易主体行为策略选择的影响程度的研究表明,构建"准市场"机制下的排水权交易制度可以促进区域主体运用经济手段解决洪涝灾害问题。在洪涝灾害时期,各地区应从区域整体利益出发,积极谈判交易排放洪水的权力。发达地区通过购买欠发达地区的排水权,以减轻洪水给自身带来的损失;欠发达地区利用出售排水权获得的收益进行灾后重建,这样可以使区域整体洪涝灾害损失降至最低,促进区域和谐稳定发展。
During the flood period, in order to solve the problem of discharging flood between the upstream and downstream of the basin and between the main bodies of the left and right banks, it is urgent to construct a drainage right trading system under the quasi market. Based on the problem of flood control and drainage in China's regions, the concept of drainage right is put forward, and the system framework and operation mechanism of drainage right transaction under "quasi market"are designed. By constructing an evolutionary game model of inter-regional drainage rights trading, the influencing factors of inter-regional drainage rights trading are discussed. Finally, the simulation study is carried out by using MATLAB software to analyze the impact of the changes of the influencing factors on the behavior strategy choice of the trading subjects. The results show that the establishment of the drainage right trading system under the quasi market mechanism can promote the regional main body to use economic means to solve the flood disaster. During the period of flood disasters, all regions should actively negotiate and trade the power to discharge flood water from the perspective of the overall interests of the region. Developed areas can reduce the losses caused by floods by purchasing the drainage rights of underdeveloped areas. Underdeveloped areas can use the proceeds obtained from the sale of drainage rights to rebuild after disasters, so as to minimize the overall loss of flood disasters in the region and promote the harmonious and stable development of the region.
