我国数字孪生技术发展趋势与瓶颈

Abstract:Digital twinning is the key technology of industrial digitalization. At present，North America and Europe are leading in digital twin technology development，and the Asia-Pacific region has the fastest growth，while China is still in the second gradient in the world. The lack of innovation in chip，simulation and modeling in China has seriously restricted the application depth of digital twins technology in smart manufacturing and smart cities. China’s digital twin development needs to break through the four bottlenecks of “cutting-edge technology catching up，key technology sticking，limited large-scale application，and lack of standards and specifications”，and needs to improve the top-level design，strengthen technical research，speed up application and promotion，and strengthen the construction of digital twin standards.
