Economic nationalism is a body of policies that emphasize domestic control of the economy, labor, and capital formation, even if this requires the imposition of tariffs and other restrictions on the movement of labor, goods and capital. In many cases, economic nationalists oppose globalization or at least question the benefits of unrestricted free trade. Economic nationalism may include such doctrines as protectionism and import substitution.
Examples of this include Henry Clay's American System, French Dirigisme, Japan's use of MITI to "pick winners and losers", Malaysia's imposition of currency controls in the wake of the 1997 currency crisis, China's controlled exchange of the yuan, Argentina's economic policy of tariffs and devaluation in the wake of the 2001 financial crisis and the United States' use of tariffs to protect domestic steel production.
Instances became more visible from 2005 after several governments intervened to prevent takeovers of domestic firms by foreign companies. Some cases include:
- Proposed takeover of Arcelor (Spain, France and Luxembourg) by Mittal (India).
- French governmental listing of Danone (France) as a 'strategic industry' to pre-empt a potential takeover bid by PepsiCo (USA).
- Blocked takeover of Autostrade, an Italian toll-road operator by the Spanish company Abertis.
- Proposed takeover of Endesa (Spain) by E.ON (Germany), and the counter-bid by Gas Natural (Spain).
- Proposed takeover of Suez (France) by Enel (Italy), and the counter-bid by Gaz de France (France).
- United States Congressional opposition to the takeover bid for Unocal (USA) by CNOOC (PR China), and the subsequent takeover by Chevron (USA).
- Political opposition in 2006 to sell port management businesses in six major U.S. seaports to a company DP World based in the United Arab Emirates
- Case of new draft legislation at the beginning of 2007 restricting foreign companies' access to Russia's natural-resource wealth and selected Russian industries.
- The New Zealand Government veto of the Canada Pension Plan Investment Board's bid for a majority stake in Auckland Airport in 2008. 
- The renationalization since 2003 in Argentina of numerous formerly state-owned firms privatized during the 1990s; some of the most significant firms controlled by foreign ownership at the time of their renationalization include Aguas Argentinas (the water utility serving Buenos Aires), Aerolíneas Argentinas, the energy firm YPF, and Metrogas.
The reason for a policy of economic protectionism in the cases above varied from bid to bid, In the case of Mittal's bid for Arcelor, the primary concerns involved job security for the Arcelor employees based in France and Luxembourg. The cases of French Suez and Spanish Endesa involved the desire for respective European governments to create a 'national champion' capable of competing at both a European and global level. Both the French and US government used national security as the reason for opposing takeovers of Danone, Unocal, and the bid by DP World for 6 US ports. In none of the examples given above was the original bid deemed to be against the interests of competition. In many cases the shareholders supported the foreign bid. For instance in France after the bid for Suez by Enel was counteracted by the French public energy and gas company Gaz De France the shareholders of Suez complained and the unions of Gaz De France were in an uproar because of the privatization of their jobs.
Economic patriotism is the coordinated and promoted behaviour of consumers or companies (both private and public) that consists of favoring the goods or services produced in their country or in their group of countries. Economic patriotism can be practiced either through demand stimulation (encouraging consumers to purchase the goods and services of their own country) or through supply protection, the shielding of the domestic market from foreign competition through tariffs or quotas (protectionism). A recently emerging form of economic patriotism is financial protectionism, the hostility against acquisitions by foreign groups of companies considered of "strategic value" for the economy of the country.
The objective is to support economic activity and promote social cohesion. The supporters of economic patriotism describe it as a kind of self-defence of local economic interests (national or European in case of the countries of the European Union). Some manifestations of economic patriotism are attempts to block foreign competition or acquisitions of domestic companies. An often cited example is France, where economic patriotism was the main rationale used in the Pepsico-Danone, Mittal-Arcelor, and GDF-Suez affairs.
In the United States, an example of economic patriotism would be the numerous bumper stickers: "Be American, Buy American".
Consumer preference for local goods gives local producers more market power, affording them the ability to lift prices to extract greater profits. Firms that produce locally produced goods can charge a premium for that good. Consumers who favor products by local producers may end up being exploited by profit-maximizing local producers. For example; a protectionist policy in America placed tariffs on foreign cars, giving local producers (Ford and GM market) market power that allowed them to raise the price of cars, which negatively affected American consumers who faced fewer choices and higher prices.
Locally produced goods can attract a premium if consumers show a preference towards it, so firms have an incentive to pass foreign goods off as local goods if foreign goods have cheaper costs of production than local goods. This is a viable strategy because the line between foreign-made and locally-made is blurry. However, as supply chains expand globally, the definition of local goods becomes hazy. For example, while a particular car may be assembled in America, its engine may be made in another country such as China. Furthermore, while the engine may be made in China, the engine's components may be imported from several other countries: the pistons may come from Germany and the spark plugs may come from Mexico. The components that make up the spark plugs and pistons may come from different countries and so on.
