1. Overview of the digital twin industry
Digital twins implement the construction of a digital model of physical objects in the digital space based on data integration and analysis, so as to realize the transmission of physical information from real to virtual to virtual to virtual world, and then make optimization decisions through simulation, verification, prediction and control of the entire life cycle behavior of physical entities, and ultimately realize the feedback empowerment of the physical entities by virtual entities.
1, development history
Review the development history of digital twins. Before the 21st century, the birth of pre-technology such as CAD/CAE series of software and system engineering laid a technical foundation for digital twins. The concept originated in the fields of aviation and air force in the early days. With the development of the concept in recent years, it has gradually entered the fields of urban management, industry, transportation, etc. At the same time, relevant academic research on digital twins has also shown a rapid growth trend.

2, Digital Twin City Technology Structure Diagram
Currently, the technology providers of China's digital twin city market include three types of roles: infrastructure solution provider, platform-level solution provider and integrator. As the core of the digital twin city market, the platform-level market includes market sectors such as simulation deduction, visualization, interactive control, and urban information model. The overall market size is still small, but the growth rate is relatively high.

3, Industrial advantages
Take the automotive R&D link as an example, in the styling stage, digital twin solves the problems of data lag and difficulty in backtracking; solves the systematic and collaborative verification problems of traditional distributed simulation in the virtual simulation stage; solves the failure risks and economic problems of physical experiments in the prototype test stage. Overall, digital twins can save about 20% of time and 40%-45% of R&D costs under the same experimental standards. Its multi-dimensional and multi-field virtual verification methods make it one of the key technologies for R&D digitalization.

2. Digital twin policy background
In recent years, many ministries and commissions have also issued policy documents to guide and accelerate the application of digital twin technology in urban construction. "Exploring the Construction of Digital Twin Cities" was included in the "Outline of the 14th Five-Year Plan for National Economic and Social Development and the Long-Term Goals for 2035" for the first time, providing national strategic guidance for the construction of digital twin cities.

3. Market size
1. Market size
1. Market size
In terms of changes in the global digital twin market size, data shows that the global digital twin market size in 2020 was US$5.22 billion, and it will usher in rapid growth in the next few years. It is expected that the market size will reach US$26.46 billion in 2025. As the digital twin market expands, digital twin technology will become more mature and its application scope will be expanded, and it is ultimately expected to achieve world twins in the metaverse.

2, related academic research
The number of published literatures in digital twin cities shows a rapid growth trend. In the past five years, the research on "digital twin" has been very popular, and the number of papers has shown an explosive growth trend. Digital twin cities have developed relatively late. In 2017, there were only 8 related papers in the world, but the number of papers has increased significantly in recent years. By October 2021, the cumulative number has reached 445. From a country perspective, the United States, China and South Korea are the three countries with the most papers published in the field of digital twin cities.

5. Current status of digital twin demand
1, application situation
Digital twin cities recreate a corresponding "virtual world" in cyberspace by digitizing all elements such as people, objects, events, etc. in the physical world, forming a pattern of coexistence and coexistence in the physical dimension and the digital world in the information dimension. By building urban digital twins, in the form of a combination of quantitative and qualitative, the interactive operation of factors such as weather environment, population and land, industrial transportation and other factors are deduced in the digital world, and the "urban portrait" is drawn to support decision makers to achieve the optimal layout of comprehensive benefits of urban planning in the physical world. It is currently widely used in public services/management, community development and smart buildings.

6. Digital twin technology promotes the implementation of the industry
Digital twin cities emphasize data driving, and real and instant city information is the basis for ensuring the operation of the digital twin city model. The digital twin city technology architecture is complex and is comprehensively supported by a variety of information technology systems such as digital identification, automatic perception, network connection, collaborative computing, new surveying and mapping, and 3D modeling. The development and change of each technology will affect the process of digital twin city construction. The increasing maturity of basic technologies such as the whole-domain perception system, edge computing , 5G, artificial intelligence is the cornerstone of the digital twin city. It realizes the acquisition of more and more accurate physical city information, faster information interaction capabilities, more complete data processing integration level, and more optimized decision-making capabilities, which will promote the implementation and maturity of digital twin cities.
