  It is worth noting that since the last trading day (18th), the "East and West" sector broke out, and it detonated again today (21st).

Among the concept sectors, the concept sectors related to data center, edge computing, and big data are among the top gainers.

  In the news, recently, China's National Development and Reform Commission and other departments jointly issued a notice, agreeing to start the construction of national computing power hub nodes in 8 places, and planned 10 national data center clusters, and the "East Digital Western Computing" project was officially launched.

  In this regard, the research team of Shengang Securities pointed out that with the full implementation of "East Digital and Western Calculation", the relevant industrial chain is expected to benefit.

Through the construction of computing power hubs and data center clusters, upstream and downstream investment in the industry will be vigorously driven.

  The research team of Essence Securities believes that the "East and West Calculation" project is an important infrastructure and a starting point for the digital economy industry, which is expected to drive the digital economy-related industries to achieve a wider range of computing power applications.

At the same time, "East and West Calculation" is the starting point for the implementation of the digital economy policy, and more related construction projects may be introduced in the future.
