In terms of profits, the total profits of "key enterprises" achieved a year-on-year growth rate of 9.1% from January to April. This data may seem impressive, but compared to January to March, the growth rate has dropped significantly by 28.6 percentage points. The decline in profit growth reflects that the industry's profit margins have been squeezed to a certain extent under multiple pressures such as rising costs and intensified market competition.

The fluctuation of raw material prices, the increase in labor costs, and the improvement of environmental protection requirements have all brought challenges to the cost control of enterprises. However, even in such difficult circumstances, key enterprises were able to maintain a profit growth rate of 9.1% and drive the revenue profit margin to a good level of 3.9%, an increase of 0.3 percentage points from January to March. This fully reflects the flexibility and adaptability of enterprises in responding to market changes, as well as their efforts in improving product added value and optimizing internal management.
