Table 2.
The meaning of collaborative control cross elasticity.
| Calculated value | Meaning |
|---|---|
| Elsj/k > 0 (both the numerator and denominator are positive) | It has emission reduction effects on both the j-type air pollutant and the k-type greenhouse gas, and it has a synergistic control effect. |
| Elsj/k < 0 | It can reduce the emission of either the j-type air pollutant or the k-type greenhouse gas, while increasing the emission of the other one, which is a non-synergistic measure. |
| Elsj/k = 1 | The degrees of emission reduction of the j-type air pollutant and the k-type greenhouse gas are the same. |
| 0<Elsj/k < 1 | The degree of emission reduction of the k-type greenhouse gas is greater than that of the j-type air pollutant. |
| Elsj/k > 1 | The degree of emission reduction of the j-type air pollutant is greater than that of the k-type greenhouse gas. |
| Elsj/k > 0 (both the numerator and denominator are negative) | It promotes the emissions of both the j-type air pollutant and the k-type greenhouse gas. |
| ERj/Qj = 0 | It has no effect on the j-type air pollutant emission reduction. |
| ERk/Qk = 0 | It has no effect on the k-type greenhouse gas emission reduction. |
