Successful rental model for bikes will not work for sharing all things

AS SHARED BICYCLES PROVE POPULAR, more companies are copying the model with things such as basketballs and umbrellas. However, some of these self-claimed "sharing" businesses are unlikely to succeed. Beijing News comments:

In economics, there is a strict definition of the "sharing economy". It means people sharing their unused resources with others, so that both sides benefit and the whole society avoids wasting resources.

In this mode, a company provides a platform enabling one person to rent or lease a resource of another. An example of this is Airbnb, which offers a platform for those offering or wanting to rent a room from others. The company in turn makes money by charging a service fee.
