基于供求关系和生产函数的灌区水量使用权交易模型
Water use right trading model of irrigation area based on supply-demand relation and production function
摘要
Abstract
As market plays an increasingly important role in the allocation of resources,water right trading is imperative to optimize the allocation of water resources,improve the efficiency of water use and promote water saving,which has been an important part of the pilot construction of the most stringent water resources management system in China.In this paper,water resources system analysis and economic theory are used and water use right trading model of irrigation area is established on the base of supply-demand relation and the production function.In the model,the maximized transaction income of transactors is taken as the goal and the value of the respective water is determined by C-D production function and the supply-demand relation,and Nash equilibrium price and water quantity are bound to determine the transaction volume and transaction income.This model is applied to water use right trading between Gaoguan reservoir irrigation area and Yingcheng city in Hubei province.The results show that with the depth of water saving in Gaoguan reservoir irrigation area,transaction volume is maximal under 50% conditions of current year 2013,planning year 2020 and 2030,which are 37.447 million cubic metres,47.44 million cubic metres,58.29 million cubic metres,respectively;trading amount of dry year of 75% and 85% are reduced among 12.25 million cubic metres to 41.81 million cubic metres,and 2.14 million cubic metres to 15.70 million cubic metres,respectively;conditions of water use right trading are lacked in special drought year of 90%.Water use right trading can not only ease the level of water shortage significantly under 50% conditions of current year 2013,planning year 2020 and 2030 in Yingcheng city and make water shortage rate decreased,but also improve net benefit of Gaoguan reservoir irrigation area by 2.02 million yuan to 705.42 million yuan and improve net benefit of Yingcheng city by 0.88 million yuan tol.32 billion yuan;but to fully solve the problem of water supply in Yingcheng city for drought year,it is necessary to establish water saving capacity trading income compensation investment mechanism of water saving in irrigation district,mobilize the enthusiasm of water conservation and fully tap the local water saving potential.It is of great significance to establish and improve the water right trading mechanism and the most stringent water management system,improve the utilization efficiency of water resources,guide water saving society construction in China,ensure the safety of urban and rural water supply.关键词
