Why is it beneficial for a country to make more money from exporting that it must spend on imports?

Export and import are activities related to international trade related, respectively, to the entry (purchase) and exit (sale) of products from a given country.

Export refers to the activity of selling, sending or donating products, goods and services from one country to another. Basically, it means the departure of a national item or service to another country.

Many companies decide to export in order to grow economically by expanding business and trade beyond the domestic market.

Importation refers to the activity of purchasing products, goods or services from abroad to other countries. Basically, it is the entry of foreign items in a given country.

Even with large territories and an abundance of wealth, no country is self-sufficient. Thus, it is inevitable that countries import items or goods which they are unable to produce. These imports can be carried out with the objective of supplying industrial sectors with raw materials, goods and services, making research feasible or supplying the population with food.

Export and import are important commercial activities that establish the economic dynamics of several countries. Although they can present disadvantages, both are necessary, since they attend to the country's privileges and deficiencies.

When we refer to the trade balance, obviously, it is expected to be positive, that is, that the country exports more than it imports. This does not mean, however, that the import is negative, since this is a way of meeting the needs in relation to the goods or services that are not produced by the country.
