Now that the recession（经济衰退）is most likely over, it’s time to start looking at which companies, institutions, and individuals developed well during this unpleasant period. In the downturn that began in December 2007, the recession ruined the wealthiest cconsumer markets—the united States, Europe, Japan—there were very few safe shelters. But some countries, such as Peru, managed to grow right through the global recession. And some companies arranged their business so that they resisted the contraction and benefited from the trends affecting their industry. Some even managed to bring more business.

Chief among the Great Recession’s winners is McDonald’s. McDonald’s sales growth in 2008 was greater than in 2006 and 2007. while many restaurants reduced their business operation, it opened nearly 600 stores in 2008. and the chain has achieved same-store sales growth in each of 2009’s first seven months.

In 2008, after a decade of severely trading up to higher quality consumer goods and services, Americans began to trade down with a vengeance（报复）. McDonald’s, which has 44 percent of its 32,000 stores in the United States, was set up to profit from trading down in two ways. Fist, in a recession, people eat out less and at home more frequently. And when they eat out, they eat at cheaper places. McDonald’s is so cheap, efficient, and convenient that it was a practical alternative to casual restaurants like Ruby Tuesday.

In the United States, McDonald’s may be a cheap source of calories in food. In other parts of the world, McDonald’s is an appealing brand, identified with middle-class, westernized consumerism. Much of the world, such as China, India, is still not developed for the Golden Arches. Coincidentally, these are the right places where its business has continued to grow during the global recession. While it faces operational challenges in markets, McDonald’s has benefited form a weakening dollar and rising incomes in Asia.

The question now for investors（投资者）is whether McDonald’s can survive the recovery.

When people feel better-off, will they still stop by? The growth in same-store sales in the United States has come down a little in recent months. And there’s a rising amount of the population that has grown accustomed to eating healthier and better. Going forward, McDonald’s may face larger cultural barriers in the United States than in China.
