The Elements,structure And Model Of Smart City System

Smart City is a new concept of urban development in recent years, it attracted widespread attention as soon as it entered the people’s vision. The academic circles explored to define the concept and build theoretical models of smart city from different perspectives and with different forms of analysis.Focus on the core issue”What is the Smart City”, the paper started from the origin of the smart city concept, combining with the basic laws of the urban evolution and the typical view of the smart city, it analyzed the basic connotation of the smart city and smart city system; based on this, the paper summarized the main dimensions of the smart city with method of co-word analysis and social network analysis. Through standardized theoretical analysis, the paper analyzed the elements and hierarchy of smart city systems, and build a system model of the smart city. Finally, a case study of Smart Guangzhou system was made which is based on the thoery of the smart city system.This paper has found that: 1.The mart city is a concept based on the emerging of information technology, the basic development direction of the Smart City is the sustainable development of the economy, society and environment. The artificial intelligence and human intelligence are the basic tools for a city to becoming smart, they promote the integration of the city’s various resources in the areas,optimizing the allocation of the urban core resources. In system thinking approach, the smart city itself is a complete system, the smart city system is a urban system form to be fully self-optimized, through the good coupling of intelligence of ICT and people’s wisdom. 2.The smart city system is a complex giant system compounded by various elements/subsystems, including five subsystems which are strategic systems, social systems, economic systems, support systems and space systems. From a structural point of view, the structure of smart city system is of with specific hierarchy characteristics, containing physical layer, the active layer and the strategic layer three layers with the complexity from low to high. 3. The system model of smart city depicted the main constituent elements of a complete system, it expressed the contact between the different constituent elements with a certain structure form. The system model revealed the internal mechanism of the forming, running and the development of smart city system, through the interconnected contact between strategic systems, social systems, economic systems, support systems, space systems and strategic layer, the active layer, the physical layer.The main innovation reflected in this paper is:(1) It analyzed the concept, elements and structure of smart city system, concluding some basic ideas and theories about the smart city;(2) It built the system model of smart city through standardized theoretical analysis, and made a detailed analysis of the structural relationship of smart city system model, revealing the internal mechanism of smart city system’s form, operation and development;(3) It developed the theory of urban system, and it discussed the urban system form five aspects innovatively, which were strategic system, social system, economic system, support system, and space system.
