摘　　要：提升隐含碳生产率是产业部门碳减排的关键。基于2002—2020投入产出数据与能源碳排放数据建立隐含碳生产率指标,利用LMDI-PDA综合分解法,系统梳理各效应、各细分产业部门对产业部门整体隐含碳生产率变动的影响。研究结论为:直接排放率效应对28个产业部门中的大部分产业部门的隐含碳生产率提升起到阻碍作用,排放能效效应以及能源资本替代效应则主要起积极作用;隐含碳生产率效应普遍推动三次产业隐含碳生产率上升,排放结构效应则阻碍第二产业与第三产业隐含碳生产率的增长,负向效应分别为-0.0166万元/吨、-0.0190万元/吨;对产业部门整体隐含碳生产率增长贡献最大的两个产业部门是其他服务业和建筑业。研究结论为加速推进产业低碳变革提供了理论与数据支撑。Improving embodied carbon productivity is the key to carbon reduction in industrial sectors.This article establishes embodied carbon productivity indicators based on input-output data and energy carbon emissions data from 2002 to 2020.Using the LMDI-PDA comprehensive decomposition method,the iof various effects and sub sectors on the overall changes in embodied carbon productivity in industrial sectors is systematically analyzed.The conclusion is that the direct emission rate effect hinders the improvement of embodied carbon productivity in most of the 28 industrial sectors,while the emission energy efficiency effect and energy capital substitution effect mainly play a positive role;The embodied carbon productivity effect generally promotes the increase of embodied carbon productivity in the tertiary industry,while the emission structure effect hinders the growth of embodied carbon productivity in the secondary and tertiary industries.The negative effects are-0.0166 million yuan/ton and-0.019 million yuan/ton,respectively;The two industry sectors that contribute the most to the overall embodied carbon productivity are the other service industry and the construction industry.The conclusion provides theoretical and data support for accelerating the low-carbon transformation of industries.
