– Foreign trade
All business activites that take place outside the borders of a country are called foreign trade. The purpose of participating in foreign trade is to provide the necessary tools and equipment at a cheaper, more appropriate price and to obtain the benefit and profit of trade. Obviously in foreign trade, the money exchanged for commercial transactions is foreign currency.
۱- Financial goals
Some business units are taken over by governments in order to use the country`s resources to generate revenue for the country, such as insurance companies, banks, railways, airlines and others that state-owned in IRAN.
۲- Economic goals
some other units, which operate under the supervision of governments, are run for the sole purposes of economic and strengthening the productive capacity of the country and of course, they maybe affected in some cases, but there is no way out. Because their existence is effective and necessary in the country`s macro-economy and the private sector can not invest in them, such as the construction of large industrial plants such as steel, steel production, mining, petrochemical refineries and power plants, etc.
۳- Social goals
There are other units run by governments that aim to serve social and public welfare purposes, such as health care facilities, educational institutions, welfare organizations, the post office and the telephone.
