中国产业全碳足迹网络结构——基于投入产出与社会网络分析

Network Structure of Industrial Total Carbon Footprint in China:Based on Input-Output and Social Network Analysis

应用修正投入产出模型和社会网络分析解构中国产业部门之间的全碳足迹关联关系,并分析该网络的整体、节点和社区特征。研究表明:(1)中国产业部门的全碳足迹通达性良好,呈现复杂的网络关联关系;(2)其中电热力生产及供应业、化学工业、交通运输仓储和邮电通信业、炼焦煤气及石油加工业等是产业全碳足迹网络的发散中心,建筑业、交通运输设备制造业、其他服务业、通用专业设备制造业和电气机械及器材制造业是网络集聚中心;(3)产业全碳足迹网络存在显著的社团结构,包含碳原因、碳内部作用、碳结果和碳中介4个社区。

In this paper, the modified input-output model and social network are used to analyze the relationship between the total carbon footprint of industrial departments in China, and the overall, node and community characteristics of the network are analyzed. The results show that:(1) The total carbon footprint of the industrial sector in China is well accessible and presents a complex network relationship.(2) Among them, the electric and thermal production and supply industry, the chemical industry, the transportation and warehousing and post and telecommunications industries, the coke-oven gas and petroleum processing industry are the divergence centers of the industrial all-carbon footprint network, and the construction industry, transportation equipment manufacturing industry, other service industries, general professional equipment manufacturing industry and electrical machinery and equipment manufacturing industry are the network agglomeration centers.(3) The industrial total carbon footprint network has a significant community structure, including four communities: carbon cause, carbon internal role, carbon results and carbon intermediary.
