Yulin is a place where has a serious shortage of water resources in northwest of China. With the development of economic construction in recent years, the problem has been becoming more serious than ever before. The shortage of water resources even restrained the development of economic. In this paper, we analyzed the water use and economic elasticity by the dates from 1990 to 2005, which is relationship between socio-economic and water consumption. The results showed that the average water use and economic elasticity is 0.196, that is to say when economyof Yulin increases by 1%, then water consumption will rise 0.2 percent. At the same time, we can see that the change of water use and economic elasticity in Yulin have a decline trend. According to the situation of Yulin city, we can learn that it is the results of industrial structure adjustment and the technology and management innovation, which caused the decline of average water use quota, then the contribution of those two factors are quantitatively analyzed. Results showed that water use and economic elasticity of Yulin in 1990-2005 is more impacted by industrial structure adjustment, the amount is 0.048, accounting for 58.8%, and the amount of technology and management innovation is 0.034, accounting for 41.2%. At last, we suggest that there should be more researches to be done in the optimize the industrial structure and water-saving technologies, through the reasonable restrictions under the principles of demand side management, to realize the balance of water supply and demand in chemical energy base in the long-term.
