Group 5: PTA Supply and Inventory - This week, the overall domestic PTA supply decreased due to the co - existence of maintenance and restart of two sets of Taihua's plants and the supply reduction caused by the maintenance of Dushan Energy last week. As of September 4, the domestic PTA weekly capacity utilization rate was 69.48% (- 1.38 percentage points), and the weekly output was 1.2893 million tons (- 23,600 tons).

Group 9: Strategy Recommendation - Short - term: The supply is recovering, but the overall pressure is not high. The "Golden September and Silver October" consumption season has started, but the actual improvement in demand is limited. The fundamental driving force is insufficient, and the polyester sector will passively follow the cost fluctuations in the short term. Attention should be paid to the OPEC+ meeting results and the impact of anti - involution sentiment [30]. - Medium - and long - term: The demand is expected to improve, and the operating center of the polyester sector tends to move up [31]. - Next week's focus and risk warnings include geopolitical situation changes, the OPEC+ meeting, macro - market sentiment, and the operation of upstream and downstream plants [31]
