Abstract

This study examines the copper value chain through firm-level, temporal, and multi-tier network analysis to explore risk propagation and structural evolution. By incorporating relationship duration as an edge weight in a cascading failure model, this study identifies critical firms based on their connectivity and vulnerability to disruptions. This granular approach captures the roles of both public and private firms, emphasizing the interconnectedness of the value chain. Community detection and backbone filtration reveal that while cascading failures are generally contained within tightly connected groups, key firms in metal mining and industrial machinery show significant systemic influence. Additionally, the results highlight the critical role of supporting industries beyond the core copper supply chain in ensuring overall resilience. These insights highlight the necessity of dynamic and cross-sectoral risk mitigation strategies to enhance stability and minimize disruptions in the copper value chain.

铜价值链中的风险传播：一个公司层面的网络分析

本研究透过企业层级、时间层级及多层网路分析，探讨铜价值链的风险传播与结构演化。通过将关系持续时间作为级联失效模型中的边缘权重，本研究根据企业的连通性和对中断的脆弱性确定了关键企业。这种细粒度的方法抓住了上市公司和私营公司的角色，强调了价值链的相互联系。社区检测和骨干过滤表明，虽然级联故障通常包含在紧密联系的群体中，但金属采矿和工业机械领域的关键企业表现出显著的系统性影响。此外，研究结果强调了核心铜供应链以外的支持性产业在确保整体弹性方面的关键作用。这些见解强调了动态和跨部门风险缓解战略的必要性，以增强铜价值链的稳定性并最大限度地减少中断。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
