摘要: 在数字系统深入发展和能源系统数字化转型的现实环境下,研究数能耦合协调指数和其对能源效率的直接、间接、非线性以及空间溢出效应影响具有重要意义。研究发现:数能耦合协调对能源效率提升具有直接影响,其中,能源强省和数字强省数能耦合协调分别通过技术进步和能源替代对提高能源效率产生间接效应,且存在边际效应递增的非线性特征;数字强省数能耦合协调对能源效率具有显著的空间溢出效应,但能源强省不具备。因而,应加快建设“东数西算”工程,实施动态化、差异化的数能耦合协调策略等,实现提升能源效率、建设能源强国的目标。

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
