What is a Digital City? What constitutes a digital city? What is the core of a digital city? 100

First, the technology is different.

When the digital city reproduces the traditional city in the virtual space through the digitization of urban geospatial information and all aspects of the city's information, the smart city focuses on further using sensing technology and intelligent technology to achieve automatic, real-time, comprehensive and thorough perception of the city's operating state.

Second, efficiency and service quality are different.

While the digital city has improved the management efficiency and service quality of various industries through the informatization of various industries in the city, the smart city emphasizes more on moving from the relatively closed informatization architecture of industry segmentation to the open, integrated and collaborative urban informatization architecture as a complex giant system, so as to give full play to the overall efficiency of urban informatization.

Third, the Internet is different.

While digital cities form initial business collaboration based on the Internet, smart cities pay more attention to ubiquitous interconnection and intelligent convergence services anytime, anywhere through ubiquitous networks and mobile technologies.

Fourth, the operation and development functions of cities are different.

While the digital city is committed to realizing all aspects of urban operation and development through information technology, improving the efficiency of urban operation, and serving urban management and development, the smart city emphasizes the realization of urban public value shaping and unique value creation through the participation and collaboration of all parties, the market, and social forces.

Digital Cities.

Public utility services have begun to be informatized and digitized, and social security and provident funds can be queried and paid online, but they are still in a state of separate data islands.

Smart City · Putting people at the center.

The information from the first department has penetrated into a little bit of people's lives, and the service process can feel more intelligent, and each system can provide you with personalized services, rather than cookie-cutter services. More public affairs can be handled on mobile phones, and people in the city feel convenient, welcoming, and everyone is taken care of. At its core, it's people-oriented.

Smart city is the product of the combination of digital city and Internet of Things, including ancient smart sensor network, smart control network and smart safety network.

The smart city makes full use of the new generation of information technology in all walks of life in the city, based on the next generation of innovation of the knowledge society (innovative advanced form of urban informatization, to achieve the deep integration of informatization, industrialization and urbanization, which will help alleviate the "big city disease", improve the quality of urbanization, achieve refined and dynamic management, and improve the effectiveness of urban management and improve the quality of life of citizens.

Formation Factors:

There are two driving forces to promote the gradual formation of 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 open urban innovation ecology gradually nurtured in the knowledge society environment. The former is a technical factor at the level of technological innovation, and the latter is a socio-economic factor at the level of social innovation. This shows the driving role of innovation in the development of smart cities.

At the same time, many domestic companies have also proposed architecture systems under the inspiration of "smart earth", such as the "five core platform systems of smart cities", which have been applied in smart city projects such as smart Xuzhou, smart Feng County, and smart Karamay.

Summary. Digital city is the application of computer, Internet, 3S, multi-** and other technologies to combine urban geographic information and other urban information, digitize and store on the computer network to form an urban virtual space. Through the standardization of spatial data infrastructure and the digital integration of various urban information, the construction of digital city provides a foundation for data sharing and interoperability from both technical and institutional aspects, and realizes the integrated integration of urban 3S technology and the in-depth application of informatization in various industries and fields.

Digital city is the application of computer, Internet, 3S, multi-** and other technologies to combine urban geographic information and other information of the city, digitize and store it on the network of the stool clearing machine to form an urban virtual space. Through the standardization of spatial data infrastructure and the digitization of various urban information and the integration of multiple resources, the construction of digital city provides a foundation for data sharing and interoperability from both technical and institutional aspects, and realizes the integration of urban 3S technology and the in-depth application of informatization in various industries and fields. <>

A smart city is defined as a smart city that makes the key infrastructure components and services of the city, such as utilities and public safety, more connected, efficient and intelligent through the application of intelligent computing technology. <>

When the digital city recreates the traditional city in the virtual space through the digitization of urban geospatial information and all aspects of urban information, the smart city focuses on further using sensing technology and intelligent technology to realize the automatic, real-time, comprehensive and thorough perception of the city's operating status.

Why is the ** chain innovation insufficient?

In the development process from digital city to information city to smart city, the main driving factors include:

Technological progress: The continuous progress of information technology has provided strong support for the city's informatization construction, such as the application of the Internet, Internet of Things, cloud computing, big data and other technologies. The application of these technologies has led to the continuous improvement of the informatization of cities, thus promoting the digital development of cities.

Economic development: The informatization construction of the city requires a large amount of capital and manpower investment, and these factors promote the economic development of the city. At the same time, informatization construction can also drive the development of related industries and improve the city's employment dispersion rate and economic vitality.

Policy support: Policy support is an important driving force for urban informatization construction. **Through the introduction of relevant policies and regulations, it provides policy support and financial guarantee for urban informatization construction.

Social needs: The informatization construction of cities needs to meet the needs of society, such as improving the level of public services and promoting the efficiency of urban management. The society's demand for informatization construction is also an important driving force for urban informatization construction.

In short, the driving factors of urban informatization construction include technological progress, economic development, policy support and social demand, which jointly promote the construction and development of urban informatization.
