In case of rain and snow, clean the stairs in time.
30. During this period, workshop personnel shall strengthen the inspection frequency, and report any abnormality to the superior leader in time.
In the third quarter, the industry began to show an obvious economic turning point, with the growth rate of earnings dropping month-on-month. PPI of chemical products started to show a continuous downward trend from September. Judging from the starting rate and inventory data, the industry is currently in a passive inventory replenishment cycle, and PPI of the chemical industry is likely to continue to decline. We expect that the business cycle of the industry will probably decline next year. Chemical industry in the past more than two years kept high sentiment, significantly improve enterprise profitability and sustainable exit of backward production capacity, make bibcock company have the requirement of a new round of expansion, the industry of new investment in fixed assets to complete the sales,productivity growth in the second half of the industry there have been signs of recovery, the industry is entering a new round of expansion cycle. We believe that the current industrial supply and demand pattern is undergoing marginal changes. In the past two years, the supply and demand contraction of the industry has led to tight supply and demand, which in turn has changed the logic of boosting PPI. In the future, we should focus on the growth of demand instead of the contraction of supply in the past.
The whole year focuses on the long-term layout along the three main lines of investment
1. Focusing on the new round of capacity expansion cycle, leading companies continue to expand their capacity scale, and the industry concentration is expected to be further improved.
2. In the downturn and capacity expansion cycles of the industry, we suggest focusing on enterprises with more efficient production and management. These enterprises are expected to stand out from the new round of capacity expansion cycles and further increase their market share.
3, from the perspective of the chemical industry chain internal transfer profits, we suggest that the next focus on the chemical industry chain downstream link, especially with innovative industrial chain related materials industry (mainly feature space for demand growth relatively obvious, the downstream industry expanded rapidly, high added value products), next year is expected to usher in the recovery of the profit space.
Recommended companies throughout the year
We suggest that focus on a new round of expansion cycle of the leading enterprises constant force shares (make crude oil refining - olefins and aromatics - polyester - chemical fiber industrial chain), satellite petrochemical (continuous layout along the industry chain upstream and downstream ethane, propane, wanhua chemical (MDI, TDI, new production capacity continues to expand the world leading position, long-term layout downstream areas of new materials), China shandong hengsheng (the most efficient platform for the coal chemical industry), the dragon python leagues (the chlorination process titanium pigment industry is the mainstream in the future green process).
The implementation of environmental supervision policies is less than expected, leading to the acceleration of industrial supply growth; The price of chemical products dropped sharply, which had a great impact on the profitability of some industries. Delays in starting new projects have led to lower-than-expected profits.
