摘要
高耗能行业作为中国低碳转型的重要一环,是落实碳达峰、碳中和目标的重要抓手。结合各行业/部门上下游关联,本文力求构建中国隐含碳关联网络,解析高耗能行业的碳风险传导路径,主要结论如下:(1)中国高耗能行业的碳排放总量从2007年的50.45亿t增长至2017年的74.27亿t,占比从77%增长至80%。(2)石油加工业、化学原料制品业、有色金属加工业的上下游隐含碳转移效率相对较高,而电力生产供应业、非金属制品业、黑色金属加工业则相对较低。(3)随着高耗能与其上下游行业的关联增强,隐含碳排放占比逐层降低,碳风险传导路径各有不同。(4)电力生产供应业、黑色金属加工业、非金属制品业等的单位增加值减少量对应的碳排放削减量较高,减排效率较其他行业更为显著。本研究通过构建隐含碳关联网络,解析碳风险传导的关键节点及路径,力求为中国高耗能行业的可持续低碳转型及潜在风险规避提供借鉴参考。
