Domestic export concentration of economy, index

Domestic export concentration refers to a ration that measures export concentration based on the Herfindahl-Hirschman Index, which results in values between 0 and 1. A value that is close to 1 (Maximum concentration) indicates a very concentrated portfolio of export products (or of market). On the contrary, values closer to 0 reflect a more equal distribution of export product (or market) shares.
