本文从供应链增值的角度,使用投入产出表的分析方法,提出了用增值碳排放系数来测度供应链各部门及整条供应链的碳排放,同时本文还计算供应链各部门的碳排放量、碳排放强度指标,将增值碳排放系数与碳排放量、碳排放强度进行对比分析,以证实增值碳排放系数在寻找供应链碳排放的薄弱环节时的有效性。 In this paper, from the perspective of supply chain value-added, using the input-output table analysis method, we propose to use the value-added carbon emission coefficient to measure the carbon emissions of various departments and the entire supply chain. At the same time, this paper also calculates the carbon emissions Carbon emissions intensity index, the value-added carbon emission factor and carbon emissions, carbon emissions intensity comparative analysis to confirm the value added carbon emission reduction coefficient in the supply chain to find the weak links in the effectiveness of carbon emissions.
