| 摘要: |
| 行业最小需水定额研究是用水定额管理的基础性课题.本文首先阐述了行业最小需水定额的定义,并提出3条编制原则,即因地制宜、先进性和合理性及动态调整原则.在此基础上,应用数据包络分析方法计算行业在一定用水技术管理水平下单位产值的最小取水量,以此反映该行业的最小需水定额值.最后,以上海市2004年纺织行业为例计算其最小需水定额.结果表明,数据包络分析方法能表征最小取水量与一定产出的数量关系,以此确定的行业最小需水定额,能较准确地反映行业处于最优状态时一定用水水平下创造单位产值的理论取水量. |

| Abstract: |
| Minimum industrial water-demand-quota is the fundamental research for the management of water use quota.In this paper,the definition of minimum industrial water-demand-quota is illustrated and the four basic principles are put forward,which include the following three aspects:(1)Adjusting measures to local conditions;(2)Establishing advanced and reasonable minimum water-demand-quota;(3)Adjusting the minimum industrial water-demand-quota dynamically.Afterwards,the method of data envelope analysis is employed... |
