Economic complexity index
open-in-new
<p>The economic complexity index (ECI) is a <a href="/facts/Holistic/QnIpnLr6">holistic</a> measure of the productive capabilities of large economic systems, usually cities, regions, or countries. In particular, the ECI looks to explain the knowledge accumulated in a population and that is expressed in the economic activities present in a city, country, or region. To achieve this goal, the ECI defines the knowledge available in a location, as the average knowledge of the activities present in it, and the knowledge of an activity as the average knowledge of the places where that economic activity is conducted. The product equivalent of the economic complexity index is the product complexity index or PCI. </p><p>Higher economic complexity as compared to country's income level drives economic development. </p>
