近几年，得益于物联网、大数据、人工智能、高敏传感器、AR、VR等技术和设备的快速发展，数字孪生迎来了更广阔的应用场景。作为一种对现实物体的镜像映射，数字孪生技术可以给人们在生产生活中带来极大的便利。其价值主要体现在两个方面：一是工业制造，高技术基础的制造工厂已经开始将数字孪生用于产品设计、资源分配、流程优化等方面以提高产品竞争力激发企业创新活力；二是城市治理，很多国家构建城市孪生体用于灾害减损、决策模拟、节能减排等场景。本文综述了新加坡、日本、韩国等亚洲国家对数字孪生技术的开发与应用，以期为我国的技术发展规划提供借鉴与启示。
In recent years，thanks to the rapid development of technologies and equipment such as the IoT，big data，AI，high-sensitivity sensors，AR，and VR，digital twin has been widely uesd. As a mirror image of the real-world，digital twin can provide great convenience to human society in production and life. Its value mainly lies in two aspects：one is industrial manufacturing，where high-tech factories have began using digital twin for product design，resource allocation，and process optimization to enhance product competitiveness and stimulate enterprise innovation. The other is urban governance，where many countries have built urban twins for disaster mitigation，decision simulation，and energy conservation and emission reduction. This article reviews the development and applications of digital twin at national level in some Asian countries，and provides reference and inspiration for China’s technological development planning.
