Research On The Time Defining Of Water Rights And The Efficiency Of Water Resources Allocation

With the increasing anxious and water shortage, how to optimize the disposition of water resources is now a water resources management important task. The shortage of water resources not only affected the economic and social development and people's lives, and on ecosystems and the environment also caused a strong impact. The total water consumption in China, the proportion of agricultural water up to 70 percent or more, but the face of agricultural water use efficiency is not high, an alarming phenomenon and a waste of the traditional model of water resources allocation plan has been unable to meet the socio-economic development of the status quo, The effective distribution of agricultural water ease water shortage crisis is an important part. Use of water rights theory to solve water shortage crisis, the management of water resources is one of the areas of innovation. Analysis of this water right time to affect the structure of water resources allocation efficiency of the relevant factors, explained the various factors on the efficiency of water allocation principles, thereby optimizing water on the right structure, improve the efficiency of the allocation of water resources in an effective mechanism to ease China Water crisis situation proceed to achieve the optimal allocation of water resources in the target is of great significance.First of all, this paper on the existence of water right time and the efficiency of water resources allocation theory on the relationship, that is, the right to water survival time and efficient allocation of water resources is not a simple positive (or negative) relationship, but a stage in the Changes. Then make a few typical water right time structure, including: the right to water stability, the right to water changes, water rights and water rights Ningzhi circulation. Thus revealing the right to water in the various stages of existence, the efficient allocation of water resources among the different effects. The main draw the following conclusions: (1) the right to water and stability as the right to water main to provide the established right to water expected, (2) water right changes to make the water main "acts of short-term" and the expected impact on earnings (3) water Ningzhi not conducive to the efficient allocation of water resources, (4) the right to water circulation is to achieve optimal allocation of water resources in an effective way.Second, water rights changes that the right to water instability, and the result of this instability in the non-household water use is outside the will of the circumstances, owned by some of the right to transfer or loss. Such changes in performance as: water rights holders of the change in time, the main changes in water rights and water quality changes. Water rights and lead to changes in factors can be attributed to three main categories: First, of natural causes, such as climate factors have led to uneven distribution of precipitation, this is inevitable. Second, the water rights system, such as public water rights only emphasized the basin-wide (or regional) water distribution plan, the existence of private economic entities and the cost of water rights difficult to define the problem. Third, it is national policy reasons, such as emergency inter-basin water transfer. In this paper focuses on the latter two reasons caused the water right changes. Through the changes of water rights theory and relevant case studies, and changes of water right under the water act and its performance analysis, the right to draw water to maintain the stability of improving the efficiency of the allocation of water resources significance.Again, the paper of the right to water a time structure: the right to water Ningzhi, generated by the analysis of socio-economic effects, from water resources allocation perspective, the permanent water rights holders, does not mean that the efficient allocation of water resources and Effective use. Yellow River water rights through the allocation of agricultural practice, that of the Yellow River water rights Ningzhi the impact of agricultural water resources allocation, there are four aspects: (1) not conducive to agricultural water conservation (2) not conducive to agricultural water resources in a rational flow to other sectors (3) not conducive to agricultural water in the lower reaches of the rational flow (4) not conducive to the promotion of social welfare. So to make up for the right to water Ningzhi state of the efficiency losses and achieve the optimal allocation of water resources, water rights on the original effective circulation is to solve the efficiency loss of possibilities.Finally, this exposition, from time to optimize the structure of water rights, the right to water to achieve stability in the system design and improve the water right Ningzhi and promote the right to water circulation system design. In addition the optimal allocation of water resources, is related to China's sustainable utilization of water resources, economic stability and development of an important cornerstone, the owner of water resources (countries) should maintain the right to water stability, improve the efficiency of water resources allocation to play its due Role. Therefore, this article made six recommendations, including: the right to play in the water in the initial configuration of the advantages of establishing the right to water circulation system; establish a unified water resources management; clear water diversion water rights, the establishment of the transfer fee system to achieve Water resources information disclosure; establish a sound water rights system of laws and regulations.
