Table 7
Grey relation entropy sorting between the Beijing water resources system and economic system.
| | | Added value of primary industry | Industrial added value | Added value of primary industry | Added value of primary industry | Permanent residents |
| | Total water supply | 6 | 4 | 3 | 2 | 4 | | Water consumption per capita | 7 | 3 | 4 | 3 | 5 | | Agricultural water consumption | 1 | 5 | 6 | 5 | 1 | | Industrial water consumption | 2 | 7 | 7 | 7 | 3 | | Domestic water consumption | 3 | 1 | 1 | 4 | 6 | | Ecological water consumption | 4 | 2 | 2 | 1 | 2 | | Water resources per capita | 5 | 6 | 5 | 6 | 7 |
