Ranking and clustering countries and their products; a network analysis

Por • 21 ago, 2011 • Sección: Opinion

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.
