There are two important driving forces to promote smart cities. One is the new generation of information technology represented by the Internet of Things, cloud computing and mobile Internet, and the other is the urban open innovation ecology for innovation 2.0 gradually bred in the knowledge society environment. The former is a technical factor at the level of technological innovation, while the latter is a socio-economic factor at the level of social innovation. From this we can see the driving role of innovation in the development of smart cities. Professor Meng Qingguo, secretary and vice president of Tsinghua University School of Management, pointed out that a new generation of information technology and innovation 2.0 are two genes of a smart city, and they are both indispensable. The construction of smart cities should not be ignored or only emphasize the application of technology and ignore the innovation of social economy. The smart city pilot will also standardize and promote the healthy development of smart cities, build a new urban form in the era of innovation 2.0, and lead the new urbanization road with China characteristics.
