国际贸易网络

The International Trade Network

K. Bhattacharya, G. Mukherjee, S. S. Manna

摘要:

国际贸易网络(ITN)的概念是由世界各国之间在国际一级的双边贸易关系产生的。这个网络吸引了网络研究人员的注意,因为它是加权网络的一个很好的例子,链接权重被定义为衡量两国之间的贸易量。本文分析了53年的国际贸易数据,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也有一个规模不变的结构,像许多其他现实世界的网络。

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.
