高库存、高波动下的PVC中游困局 2025年二季度，国内PVC市场呈现"高开工、高库存、高升水"的典型格局。上游生产企业开工率维持在80%以上高 位，行业库存同比增加22%，期货盘面持续保持高升水状态。然而，下游房地产行业复苏缓慢，需求端支撑乏力。 受供需错配影响，PVC现货价格在4700~5300元/吨区间宽幅震荡，价格频繁出现短期内突破5100元/吨后快速回落的 现象，给企业经营带来多重挑战。 某中型PVC管材加工企业（下称甲企业）成立于2015年，年加工PVC树脂5000吨，主要生产建筑用给排水管材。作 为塑料产业链中游企业，甲企业主要通过采购PVC原料加工成管材以赚取加工利润，但其经营长期面临显著的价格 波动风险，这也是塑料行业中小企业的普遍痛点。 以销定采模式下的价格两难 从采购端看，甲企业采用"以销定采"模式，接到工程订单后，需在3个月内完成原料采购和生产交付。2025年3月， 企业中标一批管材订单，需在6月底前交付，对应需采购PVC树脂500吨。当时PVC现货价格为4900元/吨，市场对后 续走势分歧明显：一方面，成本端走强可能推动价格上涨；另一方面，高库存又可能压制价格上涨空间。若直接按 现价 ...

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report Plastic - This week, the supply elasticity of price reduction has not been realized yet. At the end of the year, the supply increases while the demand weakens, putting pressure on prices. The Q4 may gradually enter a pattern of increasing supply and decreasing demand, and the price is under pressure [5]. Polypropylene - In the off - season, the price is under pressure, and there may be marginal changes in PDH on the supply side. The Q4 may gradually enter a pattern of increasing supply and decreasing demand, and the market supply - demand pattern is still not optimistic [92]. Summary by Directory Plastic Part Price & Spread - The basis has not strengthened significantly. The low price in North China has continued to decline, and East and South China have made up for the decline. The 5 - 9 month spread fluctuates around - 50, and the warehouse receipts remain high at a stable level. The import window is compressed, and the non - standard import profit is at a relatively high level within the year [5]. Supply - The total effective capacity growth rate is 16%. The domestic production volume growth rate is 18% in the first half of the year. The current maintenance scale in December has declined. It is expected that the supply will remain in a loose state. The import volume may still be high at the end of 2025 and the beginning of 2026 [5]. Demand & Inventory - The agricultural film start - up rate continues to decline, and the packaging film festival effect has gradually subsided. The downstream raw material inventory is maintained at a low level, and the demand for raw materials is expected to decrease. The inventory removal of the PE as a whole is not smooth, the upstream factory inventory has accumulated slightly, and the social inventory has decreased slightly [5]. Polypropylene Part Price & Spread - The basis fluctuates weakly, and the month spread strengthens slightly. The overseas price of PP rebounds and then falls back, and the import window tends to close [94]. Supply - The total effective capacity growth rate is 12.7%, and the estimated annual output growth rate is 16.7%. The planned maintenance volume at the end of the year declines, and the supply center is high. The short - term PP import volume is limited, and the export volume is expected to maintain the basic level in the short term [92]. Demand & Inventory - The downstream start - up rate is temporarily stable, but the orders of plastic weaving, pipes and other industries have weakened seasonally. The downstream is mainly digesting inventory, and the raw material procurement is sluggish. The inventory removal of PP as a whole is not smooth, and the inventory is higher than the same period of last year [93].
