摘要翻译：
本文采用加权网络分析方法，研究了世界贸易网(WTW)的拓扑特征及其随时间的演变。我们证明了WTW作为一个加权网络所显示的统计特征与使用传统的二元网络方法所获得的统计特征是非常不同的。特别是，我们发现：(i)大多数现有的联系都与薄弱的贸易关系有关；(ii)加权WTW仅是弱不协调的；㈢贸易关系更为密切的国家更加集中。

英文摘要：
  This paper studies the topological properties of the World Trade Web (WTW) and its evolution over time by employing a weighted network analysis. We show that the WTW, viewed as a weighted network, displays statistical features that are very different from those obtained by using a traditional binary-network approach. In particular, we find that: (i) the majority of existing links are associated to weak trade relationships; (ii) the weighted WTW is only weakly disassortative; (iii) countries holding more intense trade relationships are more clustered.
