报告摘要：

Understanding the complexity of international trading is critical for a variety of issues ranging from quantifying the competitiveness of individual nations to forecasting the collective evolution of the world economy. Despite the significant progress made in this direction, the economic complexity of the international trading system is mainly concentrated upon a single-layer network such as the monopartite product space network and the bipartite country-product network. In order to better capture the more detailed dynamics, we characterize the international trading system with a multi-layer network with each layer representing the transnational trading relations of a product. This framework immediately reveals the nested structure in each layer and allows us to capture the product complexity with the level of nestedness in the corresponding layer. Furthermore, the nestedness metric can be extended to evaluate the trade advantage of nations and predict their future trend of the economic growth.
