标题： Ranking and clustering countries and their products; a network analysis

摘要： 在本文中，我们分析了来自联合国的国家和产品生产数据的网络。 我们定义了国家-国家和产品-产品网络，并引入了一种基于元素相似性的社区检测新方法。 结果我们发现，国家聚类揭示了最具有竞争力国家之间的意外社会地理联系。 在同一基础上，产品聚类可以高效地用于生产商品的自下而上分类。 此外，我们定义了一个程序，以对全球市场上的不同国家及其产品进行排名。 这些分析是国家国内生产总值的良好代理，因此可能用于确定国家经济的稳健性。 显示英文摘要

摘要： In this paper we analyze the network of countries and products from UN data on country production. We define the country-country and product-product networks and we introduce a novel method of community detection based on elements similarity. As a result we find that country clustering reveals unexpected socio-geographic links among the most competing countries. On the same footings the products clustering can be efficiently used for a bottom-up classification of produced goods. Furthermore we define a procedure to rank different countries and their products over the global market. These analyses are a good proxy of country GDP and therefore could be possibly used to determine the robustness of a country economy.
