Typically, there are two main types of FDI: horizontal and vertical FDI.

Horizontal: a business expands its domestic operations to a foreign country. In this case, the business conducts the same activities but in a foreign country. For example, McDonald’s opening restaurants in Japan would be considered horizontal FDI.

Vertical: a business expands into a foreign country by moving to a different level of the supply chain. In other words, a firm conducts different activities abroad but these activities are still related to the main business. Using the same example, McDonald’s could purchase a large-scale farm in Canada to produce meat for their restaurants. However, two other forms of FDI have also been observed: conglomerate and platform FDI.

Conglomerate: a business acquires an unrelated business in a foreign country. This is uncommon, as it requires overcoming two barriers to entry: entering a foreign country and entering a new industry or market. An example of this would be if Virgin Group, which is based in the United Kingdom, acquired a clothing line in France.

Platform: a business expands into a foreign country but the output from the foreign operations is exported to a third country. This is also referred to as export-platform FDI. Platform FDI commonly happens in low-cost locations inside free-trade areas. For example, if Ford purchased manufacturing plants in Ireland with the primary purpose of exporting cars to other countries in the EU.
