An Empirical Study on the Coordinated Development of Energy-Economy-Environment-Society System in Sichuan-Chongqing Region Under the “Dual Carbon” Goals

From the perspective of regional development, this paper conducts an in-depth research on the coordinated development of four major systems, namely energy, economy, environment and society, in Sichuan-Chongqing Region against the backdrop of the Dual Carbon Goals. Breaking the limitations of the traditional energy-economy-environment analytical framework, this study incorporates the social dimension to establish a 3E+S system framework and analyzes the dynamic correlations and developmental characteristics of various regional subsystems. Meanwhile, a coupling coordination degree model is constructed for empirical analysis to comprehensively evaluate the development levels of the four systems and identify their evolutionary trends of coupling coordination. The results reveal that the coupling coordination degree of the composite system in Sichuan-Chongqing Region maintains a continuous upward trend, yet has not reached the high-quality coupling level. Accordingly, targeted development strategies are proposed to facilitate the high-quality, coordinated and sustainable development of Sichuan-Chongqing Region under the Dual Carbon Goals.
