数字经济与能源高质量发展的时空演变与耦合协调实证分析
The Spatiotemporal Evolution and Coupling Coordination Empirical Analysis of Digital Economy and High-Quality Energy Development

推动数字经济与能源高质量发展的耦合协调对实现“碳达峰”、“碳中和”目标具有重要意义。本文采用投影寻踪模型对2013~2022年中国30个省份的数字经济和能源高质量发展指数进行测算，并利用耦合协调度模型分析了两者在时空上的耦合协调发展特征。研究结果表明：(1) 2013~2022年间，数字经济发展水平持续上升，区域差异显著；能源高质量发展水平上升幅度较小，区域差异较小。(2) 各省份的耦合协调度均呈现上升态势，但存在明显的梯度差异。针对以上研究，文章提出加强政策支持与体制机制创新，推动区域协调发展，促进数字经济与能源高质量发展深度融合。
The coupling coordination between digital economy and high-quality energy development plays a crucial role in achieving the “carbon peak” and “carbon neutrality” goals. This study employs the Projection Pursuit Model to calculate the digital economy and high-quality energy development indices for 30 provinces in China from 2013 to 2022. The Coupling Coordination Degree Model is then used to analyze the spatiotemporal coupling coordination characteristics of the two. The results of the study show the following: (1) Over the study period, the level of digital economy in China continuously improved, although there were significant regional disparities; the level of high-quality energy development exhibited an overall upward trend with relatively small differences across regions. (2) The coupling coordination degree of all provinces showed an upward trend, but there were noticeable gradient differences. Based on these findings, the paper suggests promoting regional coordinated development, deepening the integration of digital economy and high-quality energy development, and enhancing policy support and institutional innovation.
