China International Capital Corporation believes that digital twinning is a process of digitally defining and modeling physical entities by using information technology, and its core idea is to realize back-feeding optimization of physical entities through the simulation, control and prediction of "digital twins". Therefore, digital twins are sometimes called "industrial meta-universe". After decades of exploration and practice, digital twinning has entered a critical stage of technology improvement and industry penetration. Manufacturers in many fields, including the Internet of things, industrial software, graphics engine, cloud computing and so on, are actively promoting the application and exploration of digital twinning in their own root technology links. Looking to the future, we believe that digital twins will continue the process of technological evolution, application expansion and standard improvement, and accelerate to enter the mature stage of commercialization of major industries.
