At the present stage, in china's central and western regions, the utilization efficiency of water resource in agriculture is very low, and agriculture production consume too much water resource so that the water resource for industry is lack, both which become the outstanding problems to the development of regional and country's economy. The state of low efficiency affects the efficiency of biotransformation of water resource in the process of grain production as well as the cycle efficiency of ecosystem. In a sense, the inappropriate configuration of water resource lowers the economic efficiency of water utilization so much that both the lack of water and the decline of its quality become the bottleneck to the economic development. Therefore, the primary purpose of this thesis is to objectively make accurate assessment on the utilization efficiency of water resource in agriculture in the central and western regions and analysis the relative factors that affect the efficiency.To begin with, the technical and institutional factors that affect the utilization efficiency of water resource in agriculture have been discussed with the analytical methods of economics in this thesis, and then the utilization efficiency of water resource in agriculture in central and western regions has been estimated with analytical methods of demonstration. On the basis of the previous analysis, many suggestions about enhancing the utilization efficiency of water resource have been put forward. This thesis is divided into six parts as follows. In the preface part, the background and significance of this research has been described, and then the domestic and international research status of this research has been summarized comprehensively. Next, the main issues and methods, which studied in the following chapters, have been generalized. In chapter two, the definitions of utilization efficiency of water resource brought forward by scholar have been summarized and developed into further extent. Next, some theories related to utilization efficiency of resource have been explained, which is the theoretical foundation of the following chapters. Chapter three mainly focused on the assessment of current situation of utilization efficiency of water resource in the central and western regions, and then analyzed the main problems that exist in these regions. In Chapter four, many factors that affect utilization efficiency, such as economy technique of irrigation and engineering, water right system, water price system, water management system, etc., have been analyzed. In chapter five, the research makes demonstrative analysis towards...
