Research On Efficiency Of Utilization Of Water Resources In Jiangxi Province

Water is the source of life, production and ecological radicals, along with economic development, people’s increasing demand for water resources, demand has become increasingly acute. Strengthening water resources management, more efficient use of water resources is to achieve optimal allocation of water resources and sustainable use of the premise and key. Jiangxi province has rich water resources, but the uneven distribution of time and space, along with growth in demand and the emergence of new problems with water. In recent years, through the industrial transfer, economic construction and social development in Jiangxi province have achieved certain results. In the area of water resources use, water amount and water structures have undergone significant changes due to regional water resources among different, different levels of economic and technological levels are different, the utilization efficiency of water resources in different regions there are often large differences. Utilization status of water resources in Jiangxi province, in order to clarify and improve the efficiency of water use in the future, this article will analyze the utilization of water resources in Jiangxi province, affecting factors and through the field of operations research, management science and economics of DEA models around the utilization efficiency of water resources in Jiangxi province, in accordance with the conclusions put forward suggestions for improvements.Chapter one: explain the purpose and significance of the article, and sorts out the theory, methods, indicators and data sources, literature, and introduces the research methods used in the research process.Chapter two: first introduced the theory of water resources use efficiency including: externality theory and institutional theory and the theory of sustainable development of water rights. Then introduces the main efficiency evaluation method. Jiangxi Province around the development and utilization of water resources, thesis, Data Envelopment Analysis(DEA) to analyze the utilization efficiency of water resources in Jiangxi province.Chapter three: time series analysis of the utilization efficiency of water resources in Jiangxi province, Jiangxi province, found that total water use increased substantially, increase industrial water as a proportion of total water, agriculture continues to be large water first in Jiangxi province, accounting for 60 per cent of the total water consumption, water consumption exhibited faster growth trends. In Jiangxi province, water problems are more obvious, irrigation water is less efficient water consumption enormous industrial water recycling rate is low, the large amount of sewage emissions; residential water waste, water-saving awareness is not strong. Through the analysis of water resource utilization and problems, combined with the theory of water resources, factors which affect water resources utilization efficiency and representativeness of the data availability and selects the GDP, agriculture, water, industrial water, domestic water, the economically active population and total investment in fixed assets in the six indicators.Chapter four: first introduced has data package complex analysis method, and on DEA model and the judge guidelines for has explained, then on DEA-Malmquist index for has introduced, both combines using can more full of reflect decision unit of efficiency level and efficiency level changes, through empirical analysis found, Jiangxi Province around city water resources using efficiency difference larger, Nanchang, and Xinyu, to of water resources using efficiency high, Yichun, and Ji’an, to of water resources using efficiency lower, Jiangxi province technology progress is unlikely to, But still was the main factor promoting water use efficiency. Finally through the principal component analysis, measuring water use efficiency of composite scores around the city, and compare the results of the two methods, compared with two kinds of methods of evaluation result is approximately the same, that data envelopment analysis to evaluate the result has a certain credibility.Chapter five: summarizes the empirical results, and making a reasonable adjustment of industrial structure and the scale of production, the efficiency of resource use as an evaluation index of the business, establishing and perfecting the management system of water resources, accelerate the introduction and extension of advanced water-saving technologies, focusing on the introduction and cultivation of talents with high quality advice.
