The construction building materials industry collectively opposes internal competition.

Do not blindly expand and incur excessive debts, resolutely resist illegal subcontracting, unauthorized subcontracts, and bid rigging, resolutely resist "zero-sum" competition - recently, 33 construction industry giants jointly issued an initiative to "fight against zero-sum", firmly saying no to the industry's ills. A senior practitioner in the construction industry stated that the industry has long had problems with low-cost bidding, contract-based funding, advance funding for construction, and long payment periods. Now, industry unity in "fighting against zero-sum" is conducive to survival of the fittest and improving the quality of long-term operation. In addition, the construction material industry, as an upstream and downstream industry, has also taken a series of actions against zero-sum, such as the cement industry will effectively promote the unity of approved production capacity and actual production capacity of clinker production lines, and promote industry transformation and upgrading; several leading companies in the waterproof construction material industry have issued "price increase letters" to alleviate the issues of rising costs and thin profits.
