Any firm that supports foreign direct investment can gain valuable advantages when trading with other nations. Foreign direct investment has also ensured a number of employment opportunities by aiding the setting up of industrial units in the host country. Often foreign direct investment brings along the fact that procurement of properties, buildings, and labour can be obtained at a fraction of the cost in host countries than would be the case within the company's home country. When firms take interest in foreign direct investment they must realize that there are certain requirements that should be met, primarily the need for competitiveness of the firm. In many cases foreign direct investment is able to provide a firm with new markets and marketing channels. Firms may wish to participate in foreign direct investment to widen their export base for goods or services. Firms that invest towards foreign direct investment may gain large sums of tax revenue from the profits of their firm.
