Business transaction taking place within the geographical boundaries of a nation is known as domestic or national business. It is also referred to as internal business or home trade. Manufacturing and trade beyond the boundaries of one’s own country is known as international business. International or external business can, therefore, be defined as those business activities that take place across the national frontiers. It involves not only the international movements of goods and services, but also of capital, personnel, technology and intellectual property like patents, trademarks, know-how and copyrights.
It may be mentioned here that mostly people think of international business as international trade. But this is not true. No doubt international trade, comprising exports and imports of goods, has historically been an important component of international business. But of late, the scope of international business has substantially expanded. Companies have started increasingly making investments into foreign countries and undertaking production of goods and services in foreign countries to come closer to foreign customers and serve them more effectively at lower costs. The fundamental reason behind international business is that the countries cannot produce equally well or cheaply all that they need. This is because of the unequal distribution of natural resources among them or differences in their productivity levels.
Due to these differences, it is not uncommon to find one particular country being in a better position to produce better quality products and/ or at lower costs than what other nations can do. In other words, we can say that some countries are in an advantageous position in producing select goods and services which other countries cannot produce that effectively and efficiently, and vice versa. As a result, each country finds it advantageous to produce those select goods and services that it can produce more effectively and efficiently at home, and procuring the rest through trade with other countries which the other countries can produce at lower costs. The international business as it exists today is to a great extent the result of geographical specialization as pointed out above.
Fundamentally, it is for the same reason that domestic trade between two states or regions within a country takes place. Most states or regions within a country tend to specialize in the production of goods and services for which they are best suited. Most developing countries which are labor abundant, for instance, specialize in producing and exporting garments. Since they lack capital and technology, they import textile machinery from the developed nations which the latter are in a position to produce more efficiently. To conclude, we can say that international business is a much broader term and is comprised of both the trade and production of goods and services across frontiers.
