All enterprises that produce, manufacture, excavate, transport and sell commodities and goods belong to the category of real economy. For example, automobile manufacturing, petroleum, chemical industry, computers, refrigerators, machine tools and other manufacturing enterprises, railway transportation, hotels, restaurants and so on. , are characterized by the production, transportation and operation of various "visible and tangible" goods, collectively referred to as the real economy. Invisible stocks and futures similar to electronic transactions belong to the category of virtual economy.
The real economy of a country must be dominant, otherwise the foundation of the national economy will be unstable. At that time, Iceland was hit by the international financial crisis because of the large proportion of virtual economy in the national economy, which led to "national bankruptcy".
The factors that determine the proportion of the real economy are the number, scale, output value, profits and taxes of enterprises in the real economy.
