"Digital city management" refers to the processing, analysis and management of all parts and event information of the whole city by means of information technology and mobile communication technology, so as to promote the smooth and coordinated flow of people, logistics, capital flow, information flow and traffic in the city. In other words, urban elements such as manhole covers, street lamps, mailboxes, garbage bins, parking lots and telephone booths are all included in the scope of urban information management, and each public property is equipped with an "ID card". If the manhole cover on the street is broken and the street lamp at the door is not lit, there is no need to make a complaint call. Under the tracking search of mobile GPS positioning system, relevant departments will find and solve the problem in the first time.

The new mode of digital city management is to combine the grid management method of 10,000-meter unit with the urban component and event management method, apply and integrate a number of digital city technologies, develop the information collector "Urban Management Link", innovate the means of real-time information collection and transmission, build a two-axis management system of the city management supervision center and the command center, and recreate the urban management process to realize an accurate, agile, efficient, all-weather and all-round coverage urban management mode.
