主力PDH装置逐步回归，丙烯偏弱运行

Report Industry Investment Rating - Unilateral: Neutral; Inter - period: After the return of device maintenance, pay attention to the PL01 - 02 high - level reverse spread opportunity; Inter - variety: None [3] Core View - Upstream device restart expectations and insufficient downstream demand drive the recent weak operation of propylene spot, and the futures market also fluctuates at a low level. On the supply side, the restart and capacity increase of Shandong Zhenhua's PDH device, the expected restart of Qingdao Jinneng, and the release of new capacity from Yulong increase the supply pressure in the short term. On the demand side, downstream factories' pre - holiday stocking provides short - term support, but the stocking demand is poor due to cost pressure, with mainly low - price rigid demand purchases. In terms of cost, geopolitical tensions and the firmness of the external propane price support the cost side of propylene [2] Summary by Directory 1.
