黄河流域数字经济发展与能源利用效率的关联特征及作用机制
Correlation characteristics and mechanism of action between digital economy development and energy utilization efficiency in the Yellow River Basin
【摘要】 为了探究数字经济对能源利用效率的影响及其作用机制,进而提升黄河流域的能源利用效率,本文基于2014—2023年78个城市的面板数据,采用非期望产出超效率SBM模型和熵权TOPSIS法分别对能源利用效率和数字经济发展指数进行测算,并运用双向固定效应模型、中介效应模型和调节效应模型分析数字经济与能源利用效率之间的关系。结果表明:(1)黄河流域的能源利用效率在研究期间不断提升,但整体水平较低,且存在显著的空间差异,呈现东高西低的分布特征。(2)数字经济对能源利用效率具有显著的正向影响,尤其在黄河下游地区的效果更为明显。(3)数字经济通过提升产业结构和科技创新水平来促进能源利用效率的提高。此外,政府干预程度对产业结构高级化和科技创新水平与能源利用效率之间的正向关系具有显著的调节效应。
【Abstract】 To investigate the impact of the digital economy on energy utilization efficiency and its underlying mechanisms, thereby enhancing energy utilization efficiency in the Yellow River Basin, this study is based on panel data from 78 cities during the period from 2014 to 2023. The non-desired output super-efficiency SBM model and entropy-weighted TOPSIS method are utilized to measure energy utilization efficiency and the digital economy development index, respectively. Furthermore, a bidirectional fixed effects model, mediating effect model, and moderating effect model are employed to analyze the relationship between the digital economy and energy utilization efficiency. The findings indicate that:( 1)The energy utilization efficiency in the Yellow River Basin has been continuously improving over the study period; however, and the overall level remains low, with significant spatial disparities characterized by a distribution pattern of "higher in the east and lower in the west".(2) The digital economy exerts a significant positive impact on energy utilization efficiency, particularly pronounced in the downstream regions of the Yellow River.(3) The digital economy enhances energy utilization efficiency by improving industrial structure and technological innovation levels. Additionally, the degree of government intervention significantly moderates the positive relationship between the advancement of industrial structure, technological innovation levels, and energy utilization efficiency.
