The New York Times comments: "For decades after its Communist revolution in 1949, China was known as 'the kingdom of bicycles'... China's cities are suddenly teeming with bicycles, and the humble one-speed, that remnant of China's collective memory, again serves as more than just a means of conveyance. It is now a digital device too, helping shape one of China's most dynamic growth engines — the so-called sharing economy. Three years ago, bike-sharing didn't exist in China. Today more than 40 companies offer the service... Who can blame China for hanging on to the term 'sharing economy'? It fits with the image that Beijing wants to project: warm, generous, egalitarian... A strategic planner at the advertising firm Havas Worldwide waxed so rhapsodic in a commentary about "the close-knit comradeship" of Chinese consumers that it seemed the idea of sharing was itself a Chinese invention... (But) The self-congratulation masks a growing awareness that, for all its economic success, China has become a hard-edged society where the spirit of sharing and social trust is in short supply."
