"Sharing" is one of the themes of urban development in the new era. From the Third United Nations Conference on Housing and Sustainable Urbanization (Habitat III), which put forward the vision of "We share a vision of cities for all", to the "sharing concept development" proposed by Chinese government, all of them contain the value of "sharing". In the context of today’s slowing economic growth, the transformative impact of information technology on daily life, the renewed enthusiasm for community spirit among urban citizens and the promotion of sustainable and green low-carbon lifestyles, the sharing concept has a high degree of adaptability in such a social environment and can propose appropriate solutions to these problems.
