新旧常态中国产业全碳足迹复杂网络比较

国民经济是由多个性质迥异且相互依赖产业构成的复杂系统,科学识别产业碳排放关联传导结构对于实现中国碳减排目标具有的重要理论及现实意义。为此,首先从直接和间接两个角度综合定义全碳足迹,基于能源消耗及生产服务修正直接消耗系数,创立函数改进容许性,及时更新投入产出表,夯实数据来源基础。再设计平衡性投入产出产业全碳足迹生命周期模型测算产业全碳足迹,基于WT指数法构建新旧常态中国产业全碳足迹复杂网络,继而从网络整体、节点地位、社团结构等角度分析新旧常态中国产业全碳足迹网络特征。经比较发现,构造的新旧常态中国产业全碳足迹复杂网络整体结构合理;较旧常态而言,新常态产业全碳足迹联系更为紧密,核心关键产业控制影响力更强,社团结构则总体保持稳定。在此基础上,提出综合衡量产业全碳足迹、全面顾及个体及整体特征、重点关注核心关键节点和充分考虑产业社团特征的对策建议,以求更有效提升新常态中国产业协同减排效率。

A comparative study on the complex networks of China's industrial total carbon footprint in the new and old normal periods

The national economy is a complex system composed of many different industries and interdependent industries. Scientifically identifying the correlation conduction structure of industrial carbon emissions is of great theoretical and practical significance for achieving the goal of carbon emission reduction in China. Therefore, the total carbon footprint was defined from the direct and indirect angles. Based on the energy consumption and the direct consumption coefficient of production service, the admissibility of the function improvement was created to update the input-output table and ram the data source base. Then the balanced input output industrial total carbon footprint life cycle model was designed to calculate the total carbon footprint of the industry. Using the WT index method, China's industry total carbon footprint complex networks in the new and old normal periods were constructed, and the characteristics of networks were analyzed from the point of view of the whole network, nodes status and community structure. By comparison, it was found that the structures of China's industrial total carbon footprint complex networks in the new and old normal periods were reasonable. Compared with the old normal period, the total industrial carbon footprint in the new normal period industry linked closer, the core key industries had stronger control influence, and the community structure was generally stable. At last, the paper put forward countermeasures and suggestions, which were a comprehensive consideration of the total carbon footprint of the industry, taking into account the individual and the overall characteristics, focusing on the key nodes and taking full consideration of the characteristics of the industrial community. And we hope this paper could improve the efficiency of China's industrial synergistic emission reduction in the new normal period.
