Research on the Coupling Coordination of Energy-Economy-Environment System in Zhejiang Province

Driven by the “dual-carbon” strategy, the coupling and coordination of energy-economy-environment systems (referred to as 3E systems) has become a key issue in promoting coordinated regional development. Taking Zhejiang Province as an example, based on the long time-series panel data from 2008 to 2022, the entropy value method is used to construct a coupling coordination degree model, and the evolution law and driving mechanism of the coupling coordination degree between systems are analyzed in multiple dimensions. The results show that the degree of coordination of the 3E system in Zhejiang Province is generally on the rise, but there are fluctuations in some years, and the degree of coupling coordination of subsystems still needs to be improved. Based on this, strategies to optimize the coupling coordination degree of 3E systems in Zhejiang Province are proposed to provide theoretical and practical references for exploring its sustainable development path.
