Abstract: The digital-energy coupling coordination index and its direct, indirect, nonlinear, and spatial spillover effects on energy efficiency are studied based on the realistic environment of in-depth development of digital systems and digital transformation of energy systems. It is found that digital-energy coupling coordination directly affect energy efficiency improvement. Among them, digital-energy coupling coordination indirectly affects energy efficiency improvement through technological progress and energy substitution in strong energy and digital provinces, respectively. There are nonlinear characteristics of increasing marginal effects. Strong digital provinces have significant spatial spillover effects on energy efficiency from digital-energy coupling coordination, but strong energy provinces do not. Therefore, we should speed up the construction of the “east-data-west-computing” project and implement dynamic and differentiated digital-energy coupling coordination strategies to improve energy efficiency and build a strong energy nation.

Key words: digital economy; energy system; coupling coordination; energy efficiency
