| 摘 要： | 通过对塔里木河下游某地区农业用水的水价弹性计算、成本效益分析和管理机制分析,指出价格机制对当地水资源的调节作用十分有限,而造成这一现象的主要原因是“政府失灵”。因此,加强政府干预、消除“政府失灵”是本地区面临的首要任务。同时,对本地区水价的制定提出了自己的意见。

| Abstract: | Through calculation of price elasticity of water demand for agricultur e in the lower reaches of the Tarim River basin, we find out that the price elas ticity in the study area is tiny.In other words, the water consumption bears lit tle relation to the water price which indicates that market mechanisms do not af fect apparently on water allocation. By cost-benefit analysis, we find that the crops in the area make contribution to water conservation to certain degrees whi le local farmers waste water seriously. In addition, we notice that local farmer s have considerable endurance with present water price owing to the high margina l product of water. So it is feasible to continue the increase of water price. W ater management analysis indicated that there exist "government failtures" of wa t er resource management in the lower reaches of the Tarim River basin. The role o f water saving via crops is due to strict planning and management. However, the local authority has special power of using water because of local protectionism which leads to waste of water. According to such analysis, we draw a conclusion t hat strengthening governmental intervention and getting rid of local protectioni sm are the principal tasks in this area. Meanwhile, some suggestions are given o n water price reform. |
