铜原料（CRM）和铜废料（CWS）是铜制品的两个主要来源。由于铜生产和消费的地理分布不均衡，国际CRM和CWS贸易发展起来。然而，没有研究探讨CRM贸易和CWS贸易之间的复杂的相互依赖关系或调查的特点，这种多元化的贸易系统。本研究使用1988年至2017年的贸易记录构建了多元贸易网络：全球CRM贸易网络和全球CWS贸易网络。回顾了1988年至2017年铜贸易的演变，并确定了多元化贸易网络中的复杂关系。研究发现，我国的水煤浆贸易与CRM贸易之间存在高度的正相关关系，但在多边贸易结构中，两者之间存在明显的差异。由核心出口国和核心进口国驱动的多边贸易结构分别在CRM贸易和CWS贸易中占据突出地位。此外，还分析了中国的限制性政策对多元化贸易体系的影响。研究结果为各国制定铜资源安全战略和维护多元化贸易体系提供了政策启示。
Copper raw materials (CRM) and copper waste and scrap (CWS) are the two main sources of copper manufactured products. Due to the uneven geographical distribution of copper production and consumption, international CRM and CWS trade developed. However, no study has explored the complicated interdependencies between CRM trade and CWS trade or investigated the characteristics of this multiplex trade system. This study uses trade records from 1988 to 2017 to construct multiplex trade networks: a global CRM trade network and a global CWS trade network. The evolution of copper trade from 1988 to 2017 is reviewed, and the intricate relationships in the multiplex trade network are identified. It is found that CWS trade has a highly positive correlation with CRM trade, but there are obvious differences between CWS trade and CRM trade in the multilateral trade structure. Multilateral trade structures driven by core exporting countries and core importing countries are prominent in CRM trade and CWS trade, respectively. In addition, the impacts of China's restrictive policies on the multiplex trade system are analyzed. The results provide policy implications for countries regarding copper resource security strategies and safeguarding the multiplex trading system.
