| 本文以海河流域8个案例区为例，研究行业水经济价值序次和主要影响因素，提出行业生产和用水属性决定了水经济价值第三产业大于第二产业和第一产业，第一产业水经济价值主要取决于菜田水经济价值和种植面积，其主要低效指标是单方水纯收入;第二 第三产业主要受行业结构影响， 第二产业的低效指标是单方水纯收入和水重复利用率， 第三产业的是成本利税率和单方水纯收入区域综合水经济价值高不一定是用水效率高，消除低效指标是提高水经济价值的重要途径。 |
| 英文摘要: |
| The ordering and impact factors of economic value of water (EVW) in eight areas of the Hehai River Basin are analyzed. The result shows that the production and water utilization techniques of differ ent economic sectors determine that the magnitude of EVW for tertiary industry is higher than that of secondary and primary industry. The EVW of primary industry is depending on the magnitude of EVW of vegetable and its planting area，its low dominant inefficiency is the main factor affecting the net income per unit water. The EVW of secondary and tertiary industries are mainly affected by the indu strial structure. The dominant determinants of inefficiency of secondary industry are net income per unit water and the rate of water reuse. Whereas，the EVW of the tertiary industry is composed of the profit and tax to cost ratio and the net income per unit water. It is concluded that the high regional integrated EVW does not correspond to high water use efficiency. The way for elevating EVW is to reduce the determinants of inefficiency. |
