The promotion of infrastructure projects in various regions to stimulate domestic demand has become the main theme in the second half of 2022. The planned investment of key projects in various places in China has increased one after another. During the critical period of "Golden September and Silver October", the demand for key projects has rebounded and the shipment volume has improved. It is expected that the volume and price of aggregates will increase steadily, and the demand for aggregates may recover.

Recently, the National Railway Group held a video conference on railway construction, requiring all construction units to start the construction of 16+4 new projects as soon as possible, so as to make due contributions to the stabilization of the economic market.

At present, a large number of national "eight vertical and eight horizontal" high-speed rail channel projects have entered the bidding stage one after another, and the goal of full start of construction will be achieved in the third and fourth quarters.
