摘要
推动数字经济与能源高质量发展耦合协调对实现“双碳”目标具有重要意义。基于2013—2020年中国30个省份的面板数据,利用耦合协调度模型、马尔可夫链、Dagum基尼系数和空间计量模型,探讨数字经济与能源高质量发展耦合协调度的时空格局、动态演进、区域差异及碳减排效应。研究发现:(1)各省份的耦合协调度均呈上升态势,但存在明显的梯度差异。(2)各省份耦合协调度在空间上呈现出东高西低的发展态势。(3)耦合协调等级存在“俱乐部趋同”特征,在短期内难以实现跨越式发展。在考虑空间因素后,耦合协调度具有“空间溢出”效应,“近朱者赤,近墨者黑”现象并存。(4)耦合协调度的空间差异总体上在不断缩小,区域间差异是耦合协调度差异的构成主因。(5)耦合协调度可以有效减少碳排放,在东中部地区,碳减排效应更明显。针对以上研究发现,认为应因地制宜实施差异化政策,积极落实“东数西算”工程,推动数字经济与能源高质量发展协同共振,有效减少碳排放。
Promoting the coupling coordination of digital economy and high-quality energy development is of great significance to realizing the“double carbon”goal.Based on the panel data of 30 provinces in China from 2013 to 2020,the article explored the spatiotemporal pattern,dynamic evolution,regional differences and carbon emission reduction effects of the coupling coordination degree of digital economy and highquality energy development by utilizing the coupling coordination model,Markov chain,Dagum’s Gini coefficient,and spatial econometric model.The results are as follows.1)The coupling coordination degree of each province shows an upward trend,but there are obvious gradient differences.(2)The coupling coordination degree of each province shows a spatial development trend of“high in the east”and“low in the west”.(3)The coupling coordination level has the characteristic of“club convergence”and it is difficult to achieve leapfrog development in the short term.After considering spatial factors,the coupling coordination degree has a“spatial spillover”effect,and the phenomenon of“One takes on the color of one’s company”exists.(4)The spatial differences in coupling coordination degrees are generally shrinking,and interregional differences are the main cause of the differences in coupling coordination degrees.(5)The coupling coordination degree can effectively reduce carbon emissions,and the emission reduction effect is more obvious in the eastern and central regions.Based on the above results,the article proposes that differentiated policies should be implemented according to local conditions,and the“East Counts,West Counts”project should be actively implemented,so as to promote the coordinated resonance of the digital economy and high-quality energy development and effectively reduce carbon emissions.
