Research Of Water Resources Value Based On The Theory Of Marginal Utility

The globe is threatened by worsening water crisis, at the same time, China isfacing a increasingly grim water situation. An important measure is to use economicinstruments to regulate the supply and demand of water resources effectively inaddition to macro-control under the condition of market economy. However, theproblem that has been baffling policy-makers in water resources management is howto determine the economic value of water resources scientifically and rationally, guidethe formation and reform of water pricing system, and a reasonable regulation ofwater resources allocation. So that to inhibit the effect of economic and social needsof the water to protect the ecological environment and economic and socialdevelopment, avoid the possibility of affecting the security and stability of society.The thesis starts with the economic value of water resources and then explores itstheoretical basis and a computational model of economic value of water resources. Ittouches upon multiple disciplines such as modern economics, ecological economics,environmental economics, resource economics and water science and othermulti-disciplinary theory. After all, combined with the actual situation of the projectarea, make use of model to calculate the economic value of water resources by sectorto provide a theoretical basis for the game played between the upstream anddownstream and the rational allocation within the region. The main contents includethe following aspects:1, The thesis summarizes systematically domestic and abroad vaqlue theory onwater resources, puts forward the water resource properties, elaborates valuemanifestation and value sources of water resources from the perspective ofsuntainable development.2, The thesis analyzes and summarizes the functions and values of waterresources in domestic, industrial, agricultural and ecological value according to theirsystem and category.3, Choose the C-D production function as the basic calculation modle ofagricaultural and industrial water resources ecomomic value based on the features andcontributions.4, Take consideration of the special nature of domestic water, and its closelyrelatationship with human survival and development, as well as the uncertainty of thecontribution to the value. Ecological economics can be selected to the value ofdomestic water based on the theory of economic value model, and use the theory of consumer surplus model checking.5, In view of the contribution and work mechanism of water resources onecological environment, the thesis illustrates, in great detail, the evaluation techniqueof water-use utility or value in ecological environment.6, According to the project area water status, the EVIEWS software is choosed tocalculate the economic value of water resources by sub-industry. Combined with thesocio-economic development project area, analyze the status quo and water users’ability to withstand. The mothod and method are being applied and proved in practice.Lastly, the thesis summarized the content of the whole research work and makessome suggestions about subsequent research and direction.
