Abstract: Antimony is a high-profile critical metal, known as “monosodium glutamate” “photovoltaic metal” “war metal”, etc. The output of China's antimony ores has continued to decline, and the global demand for antimony in the photovoltaic industry has increased significantly in recent years. In this context, a comprehensive analysis about the evolution of global antimony resources flow pattern is of great significance for China, which can help China to get a more accurate understanding of the global supply-demand situation of antimony resources and further to improve the international competitiveness of China’s antimony industry chain. This paper constructs a multi-layer network model of global antimony resources flow based on the complex network method. The temporal-spatial evolution characteristics of flow pattern of global antimony resources from 2003 to 2023 has been comprehensively analyzed. It is found that the status of secondary antimony has improved, and the proportion has increased from 12% in 2003 to 33% in 2023. China is the largest exporter of global antimony raw materials, with a cumulative export volume of 1.476 million tons. The United States is the largest importer of global antimony raw materials, with a cumulative import volume of 547000 tons. Import volume of antimony raw materials in India has increased rapidly in recent years, becoming the third largest importer of global antimony raw materials in 2023. China dominates the supply chain of global antimony raw materials, but its advantage in the upstream and midstream stage has both declined due to the decline of domestic antimony ore production. China has long been “self-sufficient” between domestic production and domestic consumption of antimony resources in the perspective of whole industry chain from 2003 to 2023, but the net export volume of antimony resources has decreased significantly. Based on the research results, it is suggested to strengthen the international competitive advantage of China’s antimony industry from three aspects: strengthening the exploration and development of domestic antimony resources, encouraging mining enterprises to go abroad and improving the recovery technology of secondary antimony.
