Abstract Based on the theory of hyperbolic geometry, the international trade network is embedded in hyperbolic space by combining the national economy with trade distance. In order to ensure the accuracy of mapping, this paper preprocesses the method of backbone network firstly. And then the geometric framework of complex network is applied to map trade network to the hyperbolic space based on wheat trade data. The results demonstrate that hyperbolic network not only reflect the structure of "core-periphery", namely the United States, Canada, Australia and other countries at the core of the trade network. Over time, major trading nations, such as the United States and Canada have been at the forefront of the world. Russia's trade influence is on the rise, while China is showing a declining trend year by year. In addition, the coordinates of the international wheat hyperbolic network reveal the economic implications.
