Abstract
A uni national company is an enterprise or a business, a venture which target is to have some customers in order to make some profits. But, it is represented in only one country. They can be smalls or big like the railway company in France SNCF for example. A multinational enterprise (MNE) may be defined as a company that owns or controls production or service facilities in more than one country. In other words, a multinational is not simply a company that trades internationally by exporting its product (or by licensing overseas producers). It actually owns (via a wholly or partly-owned subsidiary) or controls (via a branch plant, joint venture or minority shareholding) productive facilities outside its home country. Very large multinationals have budgets that exceed those of many countries. They can have a powerful influence in international relations, given their large economic influence in politicians' representative districts, as well as their extensive financial resources available for public relations and political lobbying.
