Abstract: Under the background of global economic integration,the nickel supply chain is constrained by multiple risks and presents a problem of insufficient resilience,which seriously restricts the stable development of the industry and down stream related fields.Taking the resilience of nickel supply chain as the research object,the DEMATEL-ISM-MICMAC integra tion method was used to construct an index system of influencing factors covering 10 factors in four dimensions of supply chain resistance,recovery,re-organization and renewal,and the action rules,hierarchical structure and attribute characteristics of each factor were systematically analyzed.The research shows that the macroeconomic and policy environment is the core driving force for the improvement of nickel supply chain resilience,which can leverage the resilience construction of each link of the industry through hierarchical transmission.Industrial synergy and circular development are important related factors,which form a strong linkage effect with multi-dimensional influencing factors.The influencing factors of the resilience of the nickel supply chain show distinct hierarchical characteristics,and can be divided into three categories : leading,undertaking and assisting accord ing to the driving-dependence attribute.All kinds of factors play their own roles and work together in the resilience system. Based on this,the promotion strategy is proposed from the perspective of government-enterprise coordination : the government sets up special funds,formulates targeted policies,establishes market risk prevention and control mechanisms,and strengthens macro-level driving and guidance.Enterprises consolidate the industrial foundation,increase investment in innovation and R & D,deepen the upstream and downstream coordination of the industrial chain,and implement micro-level resilience improvement measures.The government and enterprises jointly build a pilot project to improve the resilience of the supply chain,forming a promotion mechanism of the whole chain linkage.This study improves the theory and method of strategic mineral supply chain resilience research,and provides a scientific decision-making basis for ensuring the safety and stability of nickel industry chain supply chain and promoting the sustainable development of the industry.
