Abstract: In recent years, with the continuous expansion of the application field of lead ore, the demand for lead in various countries has been stimulated.Lead ore is an important supporting mineral for the development of strategic emerging industries.Lead ore trade has a certain impact on world industrial development.Because there are many countries participating in international lead trade and their trade relations are complex, this paper, based on the complex network theory, selects the international lead trade data from 1997 to 2016 to construct a directed weighted global lead trade network with countries as nodes and trade links between countries as edges, and analyzes the evolution characteristics of international lead mine trade network.The results show that the scale of global lead mine trade network is constantly growing, the number of countries participating in trade is increasing, and the volume of trade is also increasing.The degree and degree distribution of nodes in the trade network have power law distribution characteristics, and the trade relations between countries are gradually close, and trade tends to be globalized.
