Beijing is crawling with motorcycle-mounted deliverymen, one sign of the rapid growth of China's service industries. Services grew 8.3 percent last year and for the first time generated more than half of gross domestic product, or 50.5 percent. Manufacturing rose only 6 percent. "If it hadn't been for the service sector, China's economy would be in a much worse state today," says Louis Kuijs, head of Asia economics at Oxford Economics in Hong Kong. He notes that all kinds of services have expanded quickly in recent years.
