摘要

工业是碳排放的主要来源,厘清工业生产环节引发的碳转移规律性,对于实现工业减污减碳的协同发展具有重要意义。本研究基于责任分配视角,对产业碳排放进行核算,构建了碳转移加权有向网络模型,并运用社会网络分析方法,探讨了2005-2020年产业碳转移网络结构及其演化特征。结果表明:①2005-2020 年行业碳排放总体呈快速增长趋势,行业间碳排放差异较大。碳转移网络规模迅速扩大,小世界网络特征显著。碳转移网络的群落结构明显,包括高碳排放、碳传递、碳内生、高溢出四个最优关联。建筑业和金属冶炼及压延加工业是碳转移网络结构的核心,具有较强的网络控制力。针对上述特点,我们从落实协会碳减排责任分配和差异化减排措施、注重网络核心节点管理等方面提出了对策建议,以期为我国工业行业可持续低碳转型发展提供跨行业协同减排思路。

[Characterization of Industrial Carbon Emission Dynamics and Network Structure Evolution in China].

Given that industry is the major source of carbon emissions, clarifying the carbon transfer regularity triggered by industry production linkage is of great importance in realizing the synergistic development of industry to reduce pollution and carbon emissions. Based on the perspective of responsibility allocation, the study accounted for the industry carbon emissions and constructed a carbon transfer weighted directed network model and applied the social network analysis method to explore the structure of the industry carbon transfer network and its evolution characteristics from 2005 to 2020. The results showed that: ① The overall carbon emissions of industries from 2005 to 2020 presented a rapid growth trend and large differences occurred in emissions between industries. ② The scale of the carbon transfer network was expanding rapidly and the characteristics of the small-world network were significant. ③ The community structure of the carbon transfer network was obvious, including four optimal associations: high carbon emission, carbon transmission, carbon endogenous, and high spillover. ④ The construction industry and the metal smelting and rolling processing industry were the core of the carbon transfer network structure, with strong network control. In view of the above characteristics, we proposed countermeasures and suggestions in terms of implementing the allocation of carbon emission reduction responsibilities and differentiated emission reduction measures for associations as well as focusing on the management of core nodes of the network, with the intent of providing cross-sectoral synergistic emission reduction ideas for the development of sustainable low-carbon transformation in China's industry sector.
