Research on the resilience of the industry chain and supply chain network of fluorite resources from the perspective of China

Against the backdrop of intensifying global geopolitical conflicts, the rise of trade protectionism and profound adjustments to the economic landscape, the industry chain and supply chain network of fluorite resources is confronted with multiple risk impacts such as “chain shortening” “chain breaking” and “chain blocking”. Studying the network resilience in the face of shocks is crucial to safeguarding the security of the fluorite resource industry chain and supply chain. Based on complex network theory, this study constructs an upstream-midstream-downstream network of the fluorine chemical industry within the fluorite resource industry chain and supply chain. The network is measured from the dimensions of node resilience and structural resilience, and the evolutionary characteristics of its resilience during the four stages of preparation, resistance, stabilization and reconstruction are analyzed from both static and dynamic perspectives. The results show that: ①the core countries in the fluorite resource industry chain and supply chain are relatively stable, mainly including Germany, China and the United States, among which Germany has long maintained a dominant position relying on its technological and resource advantages. ②The fluorite resource industry chain and supply chain networks are all disassortative networks, with significant differences in resource endowment, industrial scale and other aspects among countries in the networks. ③The network stability is significantly affected by core nodes and key trades, and the network efficiency presents power-exponential changes and polarization effects. ④Resource complementarity, technological advantages and dynamic changes in market demand among countries provide possibilities for strategic cooperation. Based on the above conclusions, targeted policy suggestions are proposed, including strengthening resource strategic layout, optimizing network structure, cultivating key node enterprises and deepening international strategic cooperation, aiming to enhance the resilience of China’s fluorite resource industry chain and supply chain network, and promote the efficient utilization of fluorite resources and the sustainable development of the industry chain and supply chain.
