资源简介：
This dataset provides information on export diversification of 166 countries from 1962 to 2010. Export diversification is expressed as the inverse of Herfindahl–Hirschman index (HHI) of export concentration. HHI is a measure of the degree of market concentration and as a measure of specialization, outperforms others (Palan, 2010).
