中国产业全碳足迹网络结构研究--基于投入产出与社会网络分析

Research on the China"s Industrial Carbon FootprintBases on EIO-SNA Model

摘要:

应用修正的投入产出模型和社会网络分析解构产业部门之间的全碳足迹关联关系,对网络进行整体、节点和社区三个层级的特征分析。研究表明：(1)我国产业部门的全碳足迹关联密切,通达性良好,呈现复杂的网络关联关系；(2)电热力生产及供应业、化学工业、交通运输仓储和邮电通讯业、炼焦煤气及石油加工业和金属冶炼及压延加工业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产业全碳足迹网络的集聚中心；(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”四个社区。

Abstract:

Bases on the modifies Economic Input-Output Method and Social Network Analysis ,this paper deconstructs the total carbon footprint relationship between industrial sectors and analyzes the characteristics of the network at three levels of the whole, the nodes and the communities.Results are as follow:(1)The total carbon footprint of China"s industrial sector is closely related, and its accessibility is good, showing a complex network correlation;(2)The electricity and heat production and supply industry,chemical industry,transportation and storage and post and telecommunications industry,petroleum and coking gas processing industry and metal smelting and plating industry are the main divergent centers of carbon footprint outflows;The construction industry, transportation equipment manufacturing industry,other services industry,general equipment manufacturing industry and electrical machinery and equipment manufacturing industry are the main gathering centers of carbon footprint inflows;(3)The industrial total carbon footprint network has remarkable community structure, which includes “carbon causes”, “carbon internal effects”, “carbon results” and “carbon intermediaries” four communities.
