These characteristics of smart cities determine the advantages of smart cities, showing the superiority of smart cities compared with traditional urban models. Therefore, the construction of smart cities will be of great significance to the development of future cities.
With the acceleration of urbanization and the continuous improvement of the level of urban economic development, urban development has fallen into the dilemma of "aggregation" and "diffusion". On the one hand, urban development has long relied on the fundamental driving force of economic growth formed by population agglomeration and industrial agglomeration, and problems such as urban traffic congestion and environmental pollution caused by excessive agglomeration make the cost of urban agglomeration gradually exceed the benefits brought by agglomeration; On the other hand, although expanding urban geographic boundaries can effectively alleviate the scarcity of urban resources, the cost of urban sprawl is more land occupation, more expensive transportation costs, and more public financial expenditures. The extensive application of the new generation of information technology helps to realize the trade-off between the spatial agglomeration and the spatial diffusion of the city, and the urban spatial structure layout can become more free and flexible.
The information superhighway built by the new generation of information technology can shorten the logical distance between the city center and the peripheral areas. A large number of high-cost urban physical activities will be realized through virtual means such as smart business and smart government affairs, reducing the urban population agglomeration in space. and industrial agglomeration, information agglomeration will replace population agglomeration and industrial agglomeration and become a new driving force for urban economic development. The construction of smart cities will readjust the functional positioning of the city's "core-edge". The central area of the city will mainly play the role of an information hub, and other urban functions can be allocated to the urban fringe more reasonably. The efficiency of resource use, thereby effectively reducing the cost of congestion and environmental governance in the central area of the city.
In addition to the urban physical space layout, the urban development model is also one of the important contents of the urban form, which is mainly manifested in the interaction between human behavior and the environment. The extensive growth model of China's urbanization has brought huge challenges to the city's resource supply capacity and environmental carrying capacity. Therefore, it is imperative to seek a new mode of "low carbon, green and ecological" urban development. Smart city construction is precisely an effective choice for China to achieve "low-carbon, green, and ecological" urban development.
The information technology industry has the characteristics of low energy consumption and low pollution. The industry uses the "intangible" resources such as intellectual resources and information resources as the main input elements, which can effectively reduce the energy consumption of economic development. Although the carbon footprint of the information technology industry itself continues to grow, the application of information technology to other industries through smart solutions and the use of technology to change the way urban life, work, study, and tourism operate in a non-physical way can reduce emissions. The goal. It is predicted that by 2020, the emission reduction achieved by the application of information technology to other industries is equivalent to five times that of the information technology industry itself.
In view of the key problems existing in traditional industries such as unadvanced process equipment, backward management methods, low resource utilization, and low product added value, one of the important measures for the transformation and upgrading of traditional industries is to promote the integration of enterprise resource systems through information innovation. Business process reengineering, organizational restructuring and management model innovation. Driven by the concept of "integration of industrialization and informatization" in industrialization and informatization, the informatization level of China's traditional industries has been significantly improved in the past decade or so. However, unlike the traditional industry informatization that focuses on the design and implementation of a single subsystem, smart cities advocate the comprehensive implementation of intelligent transformation of enterprise product design, production, management, marketing, service and other links. Enterprise production systems, communication systems, etc. , security system, fire alarm system and other systems will achieve seamless interconnection, ubiquitous perception of enterprise micro-information, and use the cloud computing platform to process and analyze enterprise real-time data to achieve enterprise information flow, logistics, capital flow, The organic unification and integration of business flow improves the overall ability of the enterprise to operate collaboratively.
