Table 2 Classification of decoupling status
From: Spatial heterogeneity and scenario simulation of carbon budget on provincial scale in China
Degree of decoupling | D | \(\varDelta C\) | \(\varDelta GDP\) | |
|---|---|---|---|---|
Negative decoupling | Expansive negative decoupling | D ≥ 1.20 | > 0 | > 0 |
|  | Weak negative decoupling | 0 ≤ D < 0.80 | < 0 | < 0 |
|  | Strong negative decoupling | D < 0 | > 0 | < 0 |
Decoupling | Recessive decoupling | D ≥ 1.20 | < 0 | < 0 |
|  | Weak decoupling | 0 ≤ D < 0.80 | > 0 | > 0 |
|  | Strong decoupling | D < 0 | < 0 | > 0 |
Coupling | Expansive coupling | 0.80 ≤ D < 1.20 | > 0 | > 0 |
|  | Recessive coupling | 0.80 ≤ D < 1.20 | < 0 | < 0 |
