From: Entropic measure unveils country competitiveness and product specialization in the World trade web

(a) Comparison between the fine-grained (6 digit HS07 classification) entropies \(H_c\) of the countries for Eq. (10) and the coarse-grained (4 digits HS07 classification) entropies \(H^{\mathrm {CG}}_c\) of Eq. (12). The quadrant bisector marks the inequality \(H_c>H^{\mathrm {CG}}_c\) relating the two. (b) Average intra-sectorial entropy \(\Delta H_c\) of Eq. (14) plotted against the overall export of a country \(X_c\). Germany (DEU) emerges as the country with the highest \(\Delta H_c\), implying an extremely articulated structure of the export shares. The gradient of the color of every point is related to the overall number of exported products by each country in the 6 digit HS07 classification.
