摘　　要：数字技术作为一种新的生产要素逐渐融入全球生产分工体系,在绿色低碳发展的背景下,数字全球价值链成为实现减排目标的新动力。本文聚焦数字全球价值链的碳减排效应,从增加值视角出发,考察数字全球价值链对出口贸易隐含碳排放强度的影响及其作用机制。实证结果表明,数字全球价值链能够显著降低出口贸易隐含碳排放强度,且在发展中国家、服务业行业和高出口依赖度行业以及来源于非数字化行业的间接参与的抑制作用更强。进一步机制检验表明,规模效应削弱了数字全球价值链对出口贸易隐含碳排放强度的抑制作用,而技术进步效应和能源结构转型效应增强了这种抑制作用。本文的研究为数字技术赋能全球价值链实现温室气体减排目标提供了经验证据。Digital technology,as a production factor,is gradually being integrated into the global production and labor division system.Against the backdrop of low-carbon development,digital global value chains have emerged as a new driver of emission reduc-tion goals.This study examines the carbon emission reduction effects of digital global val-ue chains from the perspective of value added.We comprehensively analyze the impact of digital global value chains on the intensity of export-embodied carbon emissions and the underlying mechanisms.The empirical results indicate that digital global value chains sig-nificantly reduce the intensity of export-embodied carbon emissions.This inhibitory effect is more pronounced in developing countries,service industries,industries with higher ex-port dependence,and non-digital source industries.Further mechanism analysis reveals that while the scale effect weakens the inhibitory impact of digital global value chains on the intensity of export-embodied carbon emissions,technological progress and energy structure transformation effects enhance this impact.The findings provide empirical evi-dence that digital technology empowers global value chains and supports greenhouse gas e-mission reduction goals.
