1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - The valuation of polyolefins is at a relatively low level, and polyolefins tend to fluctuate at the bottom. In December, the supply will increase while the demand will weaken, resulting in high pressure to transfer inventory downstream. However, since the monthly spread is already at the lowest level in the past five years, if the crude oil price remains relatively stable, polyolefins will tend to fluctuate at the bottom [3][4] 3. Summary According to the Table of Contents 3.1 Supply: 12 - month refinery maintenance decreases, and supply gradually rebounds - PE: In November, the number of unit overhauls decreased, and the capacity utilization rate increased slightly. In December, the overhauls remained low. The 500,000 - ton/year low - pressure unit of BASF is planned to be put into production at the end of the year, with limited impact on linear PE. The PE output is expected to be around 2.75 million tons [3] - PP: In November, the number of overhauled units decreased, and the capacity utilization rate remained relatively stable at around 78%. The output increased significantly year - on - year, and the domestic supply was relatively sufficient. In December, although there were no new units, the overhauled units resumed production one after another, and the output is expected to increase to around 3.3 million tons [3] 3.2 Demand: Demand gradually weakens in December - PE: In November, it was the peak season for agricultural film demand, and the start - up rate remained high, but the start - up rates of other downstream industries began to decline. In December, the demand for agricultural film entered the off - season, and the demand is expected to continue to decline [3][19] - PP: In December, the traditional demand is expected to enter the off - season. Plastic weaving and injection molding manufacturers are affected by the winter consumption off - season, with fewer orders and cautious procurement. The demand is expected to decline [3][26] 3.3 Inventory: Refineries actively reduce inventory, downstream purchases on a just - in - time basis, and the pressure to reduce inventory remains high - PE: At the end of November, the overall social inventory was at a normal level, and the petrochemical inventory was slightly higher than that of the same period last year. It is still in the stage of active inventory reduction [3][37] - PP: The supply is at a high level. Although refineries actively reduce inventory, downstream purchases on a just - in - time basis, and the total inventory has increased significantly year - on - year. The pressure to reduce inventory in December remains high [3][53] 3.4 Spread: Basis weakens - LLDPE: The basis strengthens slightly, and the monthly spread rebounds slightly but is at the lowest level in the past five years due to high supply pressure [62][69] - PP: The basis strengthens, and the monthly spread continues to weaken due to high supply pressure [81][87] 3.5 Profit: Coal - based profits weaken, and oil - based profits fluctuate slightly - PE: Both oil - based and coal - based production profits have declined [101] - PP: The production profits from different raw materials show different trends, and the overall situation is complex [106]
