Openness index
Trade Openness System
From Wikipedia, the free encyclopedia
The openness Index is an economic metric calculated as the ratio of a country's total trade, the sum of exports plus imports, to the country's gross domestic product.[1] = (Exports + Imports)/(Gross Domestic Product)[2]
The interpretation of the openness index is, the higher the index, the larger the influence of international trade on domestic activities and the stronger that country's economy.[3]
