Other innovators are eager to follow, because China's digital economy now has some advantages that even the American version does not have. Instead of being fragmented among dozens of apps—one for Starbucks, others for Amazon and airlines and so on—much of Chinese commerce happens within one of the two giant networks—WeChat Pay and Alipay. People open an app and can pay for almost anything, in stores or online. The simplicity encourages further retail spending, and Facebook and Google are trying to mimic this model. It feels like the future of commerce.
