Abstract: In order to grasp the current situation of global cobalt intermediate products trade, to guarantee the supply of cobalt intermediate products resources and to deal with the potential trade risks.Based on the method of complex network, this paper establishes global cobalt intermediate products trade network and analyzes the temporal and spatial pattern of the international cobalt intermediate products trade network from 2010 to 2018.The results show that the characteristic of the global trade of cobalt intermediate products is stable and disperse.The average trade size of the trading body is relatively small and the trade transmission efficiency is high.Bilateral trade and net import mode are the most important trade modes.A few countries such as the United States, Britain, Germany and Belgium have extensive trade links, and they occupy the position of trade hub and have strong trade control ability.Although China ranks the forefront of the world in terms of trade links and trade scale, and has strong trade control ability, but its ability to cross trade restrictions is weak.In order to deal with the trade risks, China needs to take measures such as promoting diversification of supply sources, moderately expanding overseas capacity of cobalt intermediate products, implementing strategic reserves of cobalt intermediate products resources, increasing the recovery of cobalt intermediate products resources, and establishing a global monitoring system for cobalt intermediate products trade risks.
