ABSTRACT

Determining the structural positions and characteristics of multi-role sectors is critical for understanding supply chain networks. Thus, in this study, we developed an attribution analysis framework to assess the structure of sectors with multiple roles in a supply chain. Subsequently, we applied the framework in a case study, where the top-ranking Japanese sectors were identified for production-oriented, betweenness-oriented, and consumption-oriented carbon dioxide emission scores. Additionally, these attribution indicators were utilized to identify/visualize the structural positions of sectors. Using company-level data, we also evaluated the structural positions of Japanese companies in relation to their carbon disclosure project (CDP) reporting practices. The results demonstrate that a company's role in the supply chain is unlikely to be related to CDP reporting.

摘要

确定多角色部门的结构位置和特征对于理解供应链网络至关重要。因此，在本研究中，我们开发了一个归因分析框架来评估供应链中具有多个角色的部门的结构。随后，我们在一个案例研究中应用了该框架，其中日本排名靠前的行业被确定为生产导向、中介导向和消费导向的二氧化碳排放分数。此外，这些归因指标被用来识别/可视化部门的结构位置。利用公司层面的数据，我们还评估了日本公司在碳披露项目 (CDP) 报告实践方面的结构地位。结果表明，一家公司'
