As such, the concept of business exists only if you have an international company or a trading business procurement abroad. But in general I will tell what the imports and exports and what it is for the state. and as the state itself affects him and why! Imports (from Latin import – import, bring, write) – the importation of goods, it briefly. Exports (in translation from English export) in the economy – it is the export of goods designed abroad for sale in foreign markets. Imports and Exports play an important role in the economy, because affect the level of gdp and thus the extent of the country's economy. There is the concept of "net exports".
What is it? So we call the difference between exports and imports in the country. Ie If a country for a month were imported goods in the $ 1 billion and exported $ 800 million, net exports amounted to $ 20 million, or (+ $ 20 million), ie gdp has grown, and the economy too. If Export figures will be back = $ 800 million, while imports = $ 1 billion, net exports is negative (- $ 20 million). The scale of the economy in such a case should be reduced. It is clear that every country wants to be Exporter and only increase the scale of the economy. But not all countries do it.
It is believed that the U.S. is a country in which the consumption of goods is the highest in the world, so imports are generally higher than it exports, and net exports are almost always negative. In many countries around the world to keep a positive net export level by introducing high tariffs on imports and many other factors. Now you know another reason why the state rate increase on import!
