| 中文摘要 |
| 行业是碳排放的主要源头,厘清行业生产关联引发的碳转移规律,对实现行业减污降碳协同增效发展具有重要意义.基于责任分配视角核算行业碳排放并构建碳转移加权有向网络模型,运用社会网络分析方法,深入探讨2005~2020年中国行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,行业间排放存在较大差异.②碳转移网络规模迅速扩大,小世界网络特性显著.③碳转移网络社团结构明显,包含“高碳排”、“碳传导”、“碳内生”和“高外溢”这4个最优社团.④建筑业、金属冶炼及压延加工业是行业碳转移网络结构的核心,网络控制力强劲.针对上述特征,研究从落实碳减排责任分配、实施社团差异化减排措施和聚焦网络核心节点管理等方面提出对策建议,可为中国产业可持续低碳转型发展提供跨行业协同减排思路. |
| 英文摘要 |
| 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. |
