摘　　要：数字经济蓬勃发展已成为当前推动中国经济高质量发展的重要力量,同时也对生态环境和气候变化产生了深远影响。本文基于数字经济视角,采用全球多区域投入产出模型和EXIOBASE数据库,分析了2013-2022年中国对外贸易隐含碳排放及其驱动因素。研究表明,与中国对外总贸易相比,数字经济视角下中国对外贸易隐含碳排放增长率更高。高隐含碳排放行业主要包括重制造业、数字重制造业及能源工业。规模效应是碳排放增长的最大驱动因素,而碳排放强度效应则是抑制碳排放增长的关键因素,尤其体现在重制造业及数字重制造业领域。此外,数字依赖效应对进出口贸易隐含碳增长具有促进作用,对贸易隐含碳净值具有抑制作用。其中,数字依赖效应对出口隐含碳增长的促进作用更多来源于国内数字依赖效应,对进口隐含碳增长的促进作用和对贸易隐含碳净值的抑制作用更多来源于国外数字依赖效应。In recent years,the vigorous rise of the digital economy has profoundly reshaped the pattern of China's economic development.Its extensive penetration and integration have not only promoted rapid economic growth but also imperceptibly produced far-reaching impacts on the ecological environment and global climate.In this process,economic expansion is often accompanied by an increase in energy consumption.China,as one of the major contributors to global carbon emissions,faces a particularly pressing challenge to reduce carbon emissions.This article,from the perspective of the digital economy,uses the global multi-regional input-output model and the EXIOBASE database to estimate China's foreign trade-embodied carbon emissions during 2013-2022 and conducts a structural decomposition analysis of the driving factors behind carbon emissions.The article finds that compared to the overall growth rate of China's foreign trade-embodied carbon emissions,the growth rate of China's foreign trade-embodied carbon emissions from the perspective of the digital economy is higher.Heavy manufacturing,digitally intensive manufacturing,and the energy industry are the three sectors with the highest foreign trade-embodied carbon emissions from the perspective of the digital economy.Over the entire study period,the scale effect was the largest driver of the growth in foreign trade-embodied carbon emissions from the perspective of the digital economy,while the carbon intensity effect was the primary factor in mitigating the growth of foreign trade-embodied carbon emissions.Heavy manufacturing and digitally intensive manufacturing were the main sectors where the carbon intensity effect played a role in carbon reduction.The digital dependency effect has to some extent promoted the growth of embodied carbon emissions in China's imports and exports from the perspective of the digital economy,while it has slowed the growth of the net value of trade-embodied carbon emissions.The digital dependency effect's contribution to the growth of China's e
