Resilience evaluation of China’s copper resources industrial chain and supply chain
Abstract
[Objective] Copper has a wide range of applications in new energy vehicles, electric power, communication, and other fields, and is a key metal that cannot be replaced in the process of energy transformation. China is the world’s largest copper consumer and demand country, and its industrial chain and supply chain security issues are increasingly prominent, therefore it is important to scientifically evaluate the resilience of its copper resources industrial chain and supply chain. [Methods] This study constructed a comprehensive evaluation indicator system for the resilience of China’s copper resources industrial chain and supply chain from four dimensions of resilience: resistance, recovery capacity, reorganization capacity, and renewal capacity, combined with the characteristics of the copper resources industry. The independence-adjusted entropy weight method was used to evaluate the resilience of the copper resources industrial chain and supply chain from 2000 to 2021, and the indicator barrier degree model and indicator contribution degree model were applied to identify the main factors that affect the improvement of resilience. [Results] The study found that: (1) From 2000 to 2021, the resilience of China’s copper resources industrial chain and supply chain showed a fluctuating upward trend, which was more rapid after 2012; (2) The lack of resistance was the main factor that led to the slow improvement of resilience, while the improvement of renewal capacity and recovery capacity was the main path to improving the overall resilience; (3) The coordination degree of resistance, recovery capacity, reorganization capacity, and renewal capacity fluctuated and increased after 2010, which contributed to the above-average resilience of the industrial chain and supply chain. [Conclusion] China should continue to improve the level of renewal capacity and recovery capacity of the copper resources industry, facilitate the integration of industry, academia, and research, and accelerate the transformation of scientific research results; reduce the negative impact of lack of resistance, identify the risks of chain breakage, strengthen the assessment and early warning of risks, and improve the secondary recovery rate of copper resources; collaborate in all aspects of the industrial chain and talent chain, and inject green kinetic energy into the industrial chain and supply chain.
