The study takes the vanadium-titanium industry supply chain as the object, comprehensively sorts out and analyzes the development level of the vanadium-titanium industry in various regions, and finds that the current vanadium-titanium industry faces three major statuses: the vanadium-titanium industry is unbalanced in various regions;there is a shortage of professional talent resources related to the vanadium-titanium industry and the admission scores of relevant majors in colleges and universities are too high;enterprises and society lag behind in their understanding of the comprehensive utilization and health management of vanadium-titanium resources. In view of the current situation of obstruction in the vanadium-titanium industry supply chain, the study introduces digital technology, starting from the traditional vanadium-titanium industry supply chain, and realizes the optimization and coordination of the supply chain through digital means, thereby improving the flow efficiency of the supply chain and reducing the production cost of vanadium-titanium products. In addition, the study also combines the digital environment to conduct an in-depth study of the problems existing in the vanadium-titanium industry supply chain, and finally obtains an effective improvement path, which provides theoretical support and practical guidance for improving the resilience of the vanadium-titanium industry supply chain.展开更多
