Currently,there are about 270 million people aged between 18 and 30 in China,and the owning rate of smartphone among this age group is up to 92%,far above the global average of 67%.According to statistics,the annual per capita disposable income of Chinese urban residents is 24,565 yuan,with average monthly income per capita being 2,047 yuan.That means,urban residents can afford an iPhone 5 with a price of 5,288 yuan after working for 3 months.Whereas,during the first 10 months in 2012,actual per capita disposable income in America is 32,653.1 dollars,with average monthly income per capita being 3,265 dollars.That tells us,American people can afford 16 iPhones 5 by working only for one month.Calculating in this way,American people's consumptive power of iPhone 5 is 48 times that of Chinese people.But the coverage of smartphone in America is still surpassed by China,from which Chinese people's great enthusiasm towards smartphone is obvious.
