摘　　要：在“双碳”战略深入推进的背景下,基于海关数据库及能源消费数据库,从“城市-行业”尺度入手,刻画分析了中国地级市二位数工业产业碳排放的时空分布特征;采用面板数据构建固定效应模型,研究了产业关联赋能工业碳减排的影响及传导机制.结果发现:(1)东部及中西部地区中各行业的碳排放强度均有所下降,且两区域间的行业碳排放差异明显缩减.其中中西部地区同一行业类别的碳排放强度下降更加明显,工业碳减排措施成效显著.(2)提高城市内部行业的产业关联水平是降低工业碳排放的可选路径,产业关联每提高1个单位,碳排放强度平均下降0.234%,且该结果在进行一系列稳健性检验后仍然成立.(3)产业关联的工业碳减排效应在资本密集行业、中低端技术行业、西部及政府干预程度越强的城市更为显著.(4)技术创新质量与数字经济活力在产业关联的工业碳减排效应中发挥重要中介作用,产业关联通过提升技术创新的质量以及经济创新活力,推动工业碳排放强度的降低.研究结果揭开了“城市-行业”尺度产业关联促进工业行业碳减排的效用“黑箱”,可以为实现区域产业发展和低碳转型协调统一提供新的决策参考.In the context of the deepening of the “dual carbon” strategy,based on the customs database and the energy consumption database,starting from the “city-industry” scale,this study characterizes and analyzes the spatiotemporal distribution characteristics of carbon emissions from double-digit industrial industries in prefecture-level cities in China.We constructed a fixed effects model using panel data and studied the impact and transmission mechanism of industrial correlation,empowering industrial carbon reduction.Moreover,it was revealed that:(1) The carbon emission intensity of various industries in the eastern and central western regions had decreased,and the difference in industry carbon emissions between the two regions had been significantly reduced.The carbon emission intensity of the same industry category in the central and western regions decreased more significantly,and the effectiveness of industrial carbon reduction measures was significant.(2) Improving the level of industry correlation within cities was an alternative path to reducing carbon emissions.For every 1% increase in industrial correlation,the average carbon emission intensity decreased by 0.234%,a result that still held after a series of robustness tests.(3) This effect was more significant in capital-intensive industries,middle-and low-end technology industries,western regions,and cities with stronger government intervention.(4) The quality of technological innovation and the vitality of the digital economy played an important intermediary role in the carbon emission reduction effect of industrial linkage.Industrial linkage promoted the reduction in industrial carbon emission intensity by improving the quality of technological innovation and economic innovation vitality.The research results uncovered the “black box” of the effectiveness of industry correlation in promoting industry carbon reduction at the “city-industry” scale,which can provide new decision-making references for achieving coordinated and unified regional i
