Business activities are becoming increasingly worldwide as many firms spread their operations into markets abroad. Many US firms, for instance, are trying to enlarge markets by doing business in China, India, Latin America, and Russia and other Eastern European countries. Multinational corporations (跨国公司), which operate in more than one country, move operations to wherever they can find the least expensive employees who are able to do the work well.
    Production jobs requiring only basic or repetitive skills — such as sewing computer pieces — are usually the first to be moved abroad. Multinational corporations can pay these workers a small part of what they would have to pay in their own countries, and often work them longer and harder. Most US multinational businesses keep the majority of their upper-level management, marketing and finance within the United States. They employ some lower-level managers and a large number of their production workers in offices, factories, and buildings in developing countries. Multinational corporations based in the United States have moved many of their production operations to Central and Latin America, China, and Southeast Asia.
    Merger（合并） is also becoming more common than in the past. In the United States, for example, tobacco producer and food producer R. J. Reynolds Industries bought food giant Nabisco Brands to form RJR Nabisco Holdings Corp. in 1985 and in 1995 the industrial power generator, electronics and machine producer Westinghouse Electric Corporation bought media production company CBS Inc.
