研究报告 – PVC 报告 2026 年 1 月 金融研究院 探底回升，宽幅震荡 摘要 2025 年 PVC 市场在国内需求收缩—供给缓慢扩张—出口被动放量—库存 高位钝化—成本中枢下移这一链条中反复寻找均衡点。 今年突出的变化有三点：一个是外需权重显著提升，出口在内需疲弱时承 担了"逆周期稳定器"的角色。二是产能扩张的工艺与区域结构变化，新增产 能更多来自沿海乙烯法及一体化装置，这改变了行业成本曲线的形态与边际供 给弹性。其三，库存从'高位但可消化'转向'高位且黏性'——库存的季节 性波动仍在，但其对价格的边际解释力被出口与成本所部分稀释，交易逻辑更 强调"库存变化率"而非库存绝对水平。 展望 2026 年：价格中枢难以脱离弱内需、强外需、供给弹性收敛这三因 素博弈。我们建议以"供给弹性—需求弹性—贸易弹性"的三维框架来组织交 易与风险管理：供给弹性取决于新增产能兑现、装置检修与环保约束；需求弹 性取决于地产链修复速度以及基建、制造业对冲能力；贸易弹性取决于印度等 关键市场的政策与新增产能节奏。在此框架下，策略上宜更偏向"区间+事件 驱动"，并以基差、月差与跨品种成本逻辑来构建组合。 一、行情回顾 2025 ...
