Sharing economy refers to the economic phenomenon that individuals, organizations or enterprises share idle physical resources or cognitive surplus through social platforms, and provide services at a lower marginal cost than professional organizers and obtain benefits. Its essence is to rent rather than buy, and the right to control and use resources is separated. Sharing economy integrates massive, scattered and idle social resources in a platform and collaborative way, and reuses and matches supply and demand, thus realizing a new economic format that maximizes the use of economic value and social value.
