Water Property Utilization Management In Resource Economy Society

Water is a special, irreplaceable resource as well as a kind of natural resource which could be repetitively used. According to the"World Water Development Report"issued by United Nations Educational, Scientific and Cultural Organization recently, the global supply of water in the next 20 years is expected to fall by one third and there will be 20-70 million people from 48-60 countries affected by shortage of drinking water in 2050. Water will definitely become one of the most important strategic resources in 21st century.China's water resources are facing the biggest threat among all natural resources. China ranks first in the world consumption of water while the water supply per capita is far below the world's average level. According to the prediction of the State Development and Reform Commission, the gap between water supply and demand will reach 32 billion cubic meters by 2010 and will be increased to 50 billion cubic meters in 2030. Therefore, how to make effective and efficient distribution of water resource to ease contradiction between supply and demand has become a major proposition in social development.In the 11th Five-Year Plan, the central government clearly pointed out that we should comply with the basic national policy of resource conservation and environment protection to build a low-input, high-yield, low-consumption, emission, energic and sustainable economic system and a resource-saving, environment-friendly society. In order to build a resource-saving society, we should strengthen resource management, especially in water resource management to improve water usage permission and paid system, to implement water volume control, to initialize the establishment of water property distribution system and water property trade system, to sound water resource management system.There are a few key issues to analyze the impact of optimal allocation of water property on establishment of resource-saving society. This thesis will focus on the issues under the base of water property and optimal allocation of water property theory and to solve the issues like water property distribution mode, initial water property allocation model, water property trade system. This thesis did some demonstration and data analysis for Taihu Lake Watershed and the main results and conclusions are as follows:Firstly, this thesis clarifies the purpose and significance of the topic and sum up the reviews of optimal distribution of water property and some relevant studies.Secondly, this thesis studies water property theory, explain the definition of water property, characteristics of water property, and analyze the water property system. The findings are that the water property study should be based on watershed in China because of the completely non-exclusive, un-dividend, externality, inequality and scarcity features of water property. Therefore, the water property is defined as the right to use water, get profit from water, dispose of water and trade of water.Thirdly, this thesis mainly discusses the distribution model of water property. Through the analysis of three different models, we consider that the adoption of water trade distribution model will be the more effective one because it overcomes of shortcomings of government failure as well as market failure. In discussing water trade distribution model, we find that the trade distribution model based on the principle of proportional allocation could eliminate the inequality between the users. And more important, this kind of distribution model could upgrade the welfare of the whole society if the water users have the same coefficient of elasticity.Fourthly, this thesis solve the problem of water resource competitiveness on the level of"Valley to City"through multi-level, multi-objective optimization model; solve the problem of water resource competitiveness on the level of"City to Sector"through multi objective programming model. According to the data analysis of Taihu Lake Watershed, the initial water property allocation could improve the efficiency of water-saving, guide the optimization of industrial structure and increase the economic effectiveness of the entire watershed. At last, this thesis studies water property quasi-market trading mechanism by setting out in detail of two types of quasi-market auction model for water property. The one is the first price auction model and another is two sides outcry auction model. Based on these two basic models, this thesis initialize the water property quasi-market dynamic transaction model by considering both parties water property value judgment, that to say the elasticity co efficiency of water price. Based on the data analysis of Taihu Lake Watershed, this thesis use C++ computer programming language to realize the process of dynamic trading and get the equilibrium price of water property trade from primary industry to second industry in Shanghai.Through the research above, the innovative points of this issue could be summarized as follows:1. Through the analysis of two kinds of water property trade distribution model——Based on the principle of priority sharing and proportional sharing, the conclusion is that the optimal distribution of water property should be based on the principle of proportional sharing. Therefore, it's very important to clarify water property before water property allocation.2. Through choosing a reasonable target system and multi-level, multi-objective optimization model and multi-objective programming model, the thesis initializes the two level water property allocations to solve the problem of property competitiveness.3. Based on the multi-factor water property quasi-market dynamic transaction model, this thesis analyze the equilibrium price water property trade and use C++ computer programming language to realize the process of dynamic trading and get the equilibrium price of water property trade from primary industry to second industry in Shanghai.
