摘要翻译：
国际贸易网络(ITN)是指世界上两个国家之间在国际层面上的双边贸易关系。这种网络引起了网络研究者的注意，因为它是加权网络的一个极好的例子，链接权重被定义为两国之间贸易量的度量。本文通过对53年国际贸易数据的分析，详细研究了与ITN相关的不同网络相关量的变化。我们的观察是，ITN也像许多其他现实世界的网络一样具有尺度不变的结构。

英文摘要：
  Bilateral trade relationships in the international level between pairs of countries in the world give rise to the notion of the International Trade Network (ITN). This network has attracted the attention of network researchers as it serves as an excellent example of the weighted networks, the link weight being defined as a measure of the volume of trade between two countries. In this paper we analyzed the international trade data for 53 years and studied in detail the variations of different network related quantities associated with the ITN. Our observation is that the ITN has also a scale invariant structure like many other real-world networks.
