"Digital Internet City" is the development trend of new smart cities. True wisdom should be taken from the people and used by the people. Only by giving people the feedback we get can the vitality of this industry continue. "People" promote social development. Urban construction should create an ecology conducive to innovative thinking, and realize the thoroughness of perception, the extensiveness of interconnection forms and the comprehensiveness of data use. Social development is a dynamic change. When an industry or an ecology develops to the extreme, it will produce another ecology, and the derived ecology can replace it or complement and integrate with its original ecology. Just like the emergence of innovative technologies such as cloud computing, Internet and big data, the construction of smart cities needs to be more adapted to the needs of the people, and it needs to provide more practical applications that benefit the people and move towards a more advanced "digital Internet city". The construction of "Digital Internet City" advocates taking "people" as the core, realizing information interconnection in an all-round way, building industry mutual assistance in an all-round way, creating a more open and cooperative ecological environment, and comprehensively improving the intelligent level of the city. Under the call of the country's "new urbanization", every role in the industrial chain should give full play to its own advantages and help build a smarter government, more dynamic enterprises and happier people.
