New Development of Sustainable Design under the Background of Smart City

The development of smart cities uses big data and computer technology to coordinate city operations. Sustainable development is an inevitable demand for future urban development. "Collaborative consumption" is one of the new consumption forms under the development of the sharing economy, which has an important role for dealing with the environmental and resource issues and realizing the sustainable development of society. In recent years, domestic and foreign scholars have continuously researched on the collaborative consumption, which enriches the new ideas for the practices of sustainable development; companies constantly explore the new modes of collaborative consumption to achieve the sustainable production and the maximization of economic benefits. This paper organizes relevant documents, materials, and business cases of collaborative consumption at domestic and foreign, summarizes its development characteristics, explores the new development direction of collaborative consumption and provides theoretical ideas for the sustainable innovative development. It has theoretical guiding significance for the construction of smart cities.
