摘要翻译：
本文探讨了国际贸易网络拓扑性质的决定因素。我们使用标准重力方程拟合双边贸易流量，建立一个“剩余”ITN，其中贸易联系权重从地理距离、规模、边界效应、贸易协定等中去除。然后我们比较了原始和剩余ITNS的拓扑性质。我们发现残余的ITN与原始的ITN不同，显示了一个复杂系统的标记签名，并且具有非常不同的拓扑结构。最初的国际贸易网络在地理上是围绕着几个大型枢纽聚集和组织的，而剩余的国际贸易网络显示了许多小规模但以贸易为导向的国家，这些国家不受地理位置的影响，要么发挥地方枢纽的作用，要么以相对复杂的贸易互动模式吸引大国和富国。

英文摘要：
This paper begins to explore the determinants of the topological properties of the international - trade network (ITN). We fit bilateral-trade flows using a standard gravity equation to build a "residual" ITN where trade-link weights are depurated from geographical distance, size, border effects, trade agreements, and so on. We then compare the topological properties of the original and residual ITNs. We find that the residual ITN displays, unlike the original one, marked signatures of a complex system, and is characterized by a very different topological architecture. Whereas the original ITN is geographically clustered and organized around a few large-sized hubs, the residual ITN displays many small-sized but trade-oriented countries that, independently of their geographical position, either play the role of local hubs or attract large and rich countries in relatively complex trade-interaction patterns.
