New infrastructure is an infrastructure construction based on science and technology, which is not only an infrastructure, but also an emerging industry. Compared with the characteristics of the old infrastructure, the new infrastructure is more of a development model with light assets, high technology content and high added value. Most of the fields involved are the shortcomings of China's economic development in the future.

The new infrastructure is essentially the infrastructure of information digitization, which mainly includes seven fields: 5G infrastructure, UHV, intercity high-speed rail and urban rail transit, new energy vehicle charging piles, big data center, artificial intelligence and industrial Internet.
