According to the TF Securities Research Report, the whole process of the supply-side reform of cement industry can be divided into two steps. In the first step, the effect of "reducing production" was achieved by controlling the new production capacity and promoting peak-shifting production nationwide, and the industry profits were pushed up to a new high in 2019. At present, the cement industry is gradually entering the second stage of supply-side reform, and it is expected to realize the withdrawal of actual production capacity with the help of market-oriented behaviors such as environmental protection, double carbon policy and enterprise merger and reorganization. In the short term, peak-shifting production is still the most effective means to adjust the balance between supply and demand. After entering 2025, with the gradual tightening of the policy of restricting overcapacity, enterprises are forced to withdraw from small and medium-sized production capacity by making up the indicators of overcapacity, and the industry is expected to begin to realize real capacity clearing. In 2027, it will enter the stage of deepening and perfecting carbon trading, and the effect of industry capacity optimization is expected to be further revealed. At present, the profit end of the cement industry has shown signs of stabilization. Under the dual promotion of policy-driven and self-restraint under the growth of corporate profit demands, the profit in the fourth quarter is expected to begin to walk out of the relative bottom.
