In the information age, the digital economy takes data as the core production factor, relying on technologies such as 5G and artificial intelligence to reconstruct the economic form. This not only gives rise to new formats such as platform economy and intelligent manufacturing, but also improves resource allocation efficiency through computing power optimization. Digital transformation is the practical path of physical organizations - enterprises use the industrial Internet to realize the digitalization of the whole production process, and the government promotes governance upgrading by "one network for all". Its essence is to use digital technology to break the efficiency bottleneck of the traditional model. The relationship between digital technology and the environment presents a two-way interaction: on the one hand, data centers and electronic devices generate energy consumption and electronic waste, bringing environmental pressure; On the other hand, digital twins can simulate pollution diffusion, and smart grids can optimize energy scheduling, providing solutions for carbon reduction. In the interweaving of the three, balancing technological innovation, economic growth, and ecological protection has become a key proposition for sustainable development in the information age.
