Countries by Economic Complexity

Japan ranks first in the world in terms of economic complexity.

Economic Complexity Index (ECI) is the measure of the sophistication of large economies such as Germany, the United States, Switzerland, and China. These nations produce a wide variety of quality products and services. Their prowess in production is a result of both their advancement in technology and highly skilled labor. They possess world-class business in industries such as automobiles, pharmaceutical products, financials, and consumer goods among others. The basis of the computation of economic complexity is economic diversity and economic ubiquity. Economic diversity refers to the number of products that a nation produces. On the contrary, economic ubiquity determines which other countries produce the goods and services produced by another nation.

Application of the ECI

The ECI is more of a predictive tool rather than a descriptive tool. It is often used to predict the economic growth of a nation in terms of GDP per capita. In addition, it also explains the international variations in the income inequality.
