全球石墨产业链贸易网络韧性研究OA

The accelerated global shift toward a green and low-carbon economy has elevated graphite to a strategic critical mineral.Ensuring a stable and secure graphite supply chain is now critical for advancing key modern sectors like new energy,new materials,and aerospace.Based on complex network theory,this study examines the resilience of the global graphite industry chain trade network from three dimensions:static structural resilience,dynamic disturbance resistance,and key node resilience.The findings indicate that:(1)the graphite trade network exhibits scale-free and small-world characteristics,yet significant structural differences exist across product tiers.The deep-processed product network is tightly connected,efficient,and resilient,whereas the raw material and primary product networks rely heavily on core nodes,display high heterogeneity,and are more vulnerable to geopolitical factors and supply shocks;(2)under dynamic scenario shocks,the primary raw material network deteriorates rapidly and recovers slowly under targeted attacks,while the deep-processed product network demonstrates stronger functional maintenance and recovery capacity due to diversified pathways and redundant connections;(3)key nodes show structural disparities in resi-lience—upstream and midstream links exhibit centralized control and high vulnerability,whereas downstream links feature more de-centralized functions and enhanced structural resilience.China holds prominent control and transit capabilities in upstream and mid-stream segments and sustains influence downstream,while countries such as the Netherlands and Germany maintain pivotal roles across the entire chain.Finally,this paper proposes policy recommendations to enhance the resilience of the global graphite trade network and ensure the security and stability of key mineral resource supply chains.
