固定资产引致碳排放与部门完全碳强度 --基于投入产出法的测算与分析.

Carbon intensity is a measure of the amount of carbon emissions generated by a unit of added value in an economy. However, the existing carbon intensity index ignores the carbon emissions caused by the fixed asset depreciation in the production process, so it is not tenable to use it in the comparative study of carbon intensity between sectors. Based on this, this paper used China's competitive input-output table in 2020 to restore the fixed asset depreciation originally located in the value-added part of the table to the intermediate consumption of the final products of each sector and used the input-output analysis method to calculate the carbon emissions caused by the fixed asset depreciation of each sector, complete carbon emission intensity, and comprehensive effect coefficient. The results showed that: ① We should not ignore the carbon emissions caused by fixed asset depreciation, which accounted for 23.28% of the total carbon emissions of all industrial sectors and 34.44% of the tertiary industry sector. ② The ranking of high-carbon sectors was different based on different carbon intensity indexes and carbon emission indexes. Considering the dual control degree of carbon emission intensity as the main control degree and total carbon emission as the auxiliary control degree, this paper suggests that complete carbon intensity should be used as the assessment index of the whole industry sector in China. ③ The analysis of factors affecting the robustness of the conclusions of this paper showed that the total amount of depreciation of fixed assets remained relatively stable in each period, and that different settings of the fixed asset depreciation rate had little impact on the robustness of the conclusions of this paper.
