成本支撑走强，聚烯烃小幅走高

Report Summary 1. Report Industry Investment Rating - Unilateral: Neutral; Inter - period: None; Inter - variety: None [3] 2. Core Viewpoints - International oil prices rebounded, strengthening the cost support of oil - based production. Propane prices rose slightly, and the profit of PDH - made PP was near the break - even point. The number of PE shutdown and maintenance devices increased, slightly alleviating the supply pressure. However, the overall current operation was still at a relatively high level, with inventory accumulation in production enterprises and certain de - stocking pressure upstream. The PP operation rate was flat month - on - month, and the inventory in the upstream and mid - stream links decreased slightly. The new 900,000 - ton/year Phase II device of Daxie Petrochemical started trial operation, and it was expected to produce qualified products soon. The continuous release of new production capacity would bring greater supply pressure in the long - term. The recovery of downstream demand was slow. The agricultural film entered the seasonal demand conversion stage, with the overall order follow - up slow and the terminal operation recovering slightly [2] 3. Summary According to the Directory a.
