摘　　要：数字经济依托互联网、云计算等高新技术,已成为引领社会变革的推动力,数字经济的蓬勃发展成为驱动经济增长新引擎。基于“一带一路”沿线47个国家的面板数据,分析数字经济对碳排放强度的影响及其内在机制,并分析数字经济碳减排的空间溢出效应,研究结果表明:数字经济发展对碳排放强度具有显著的负向影响,即随着一国数字经济发展水平的提高,其碳排放强度倾向于降低;数字经济发展水平的提高会通过“技术创新效应”“贸易规模效应”和“贸易结构效应”对一国碳排放强度产生影响;本国数字经济发展对周边国家碳排放强度具有显著的抑制作用,即一国数字经济水平的提高具有空间溢出效应。我国应持续推进数字经济高质量发展,深入挖掘数字贸易发展新动能,并搭建数字化平台,积极推动碳减排技术的国际合作。Digital economy relying on high-tech like the Internet,cloud computing has become a driving force to lead social change,and the booming digital economy has thus been a new engine to drive economic growth.Based on the panel data of 47 countries along the“Belt and Road”,this paper analyzes the impact of digital economy on carbon emission intensity and its internal mechanism,and studies the spatial spillover effect of carbon emission reduction in digital economy.The results of the study show that the development of digital economy bears a significant negative impact on carbon emission intensity,that is,with the improvement of a country’s digital economy,its carbon emission intensity tends to decrease;the impact is made through“technological innovation effect”,“trade scale effect”and“trade structure effect”;one country’s development of the digital economy takes a significant inhibitory effect on the carbon emission intensity of its neighboring countries,that is,there is available a spatial spillover effect.China,therefore,should strive to promote high-quality development of the digital economy,deeply tap into new drivers of digital trade development,build digital platforms,and actively promote international cooperation in carbon reduction technologies.
