图为国内纯碱周度产量 自9月以来，原料价格普遍上涨导致纯碱企业生产成本出现不同程度的增长，部分企业亏损加剧。虽然部分纯碱企业通过阶段性 上调价格来缓解自身成本压力，但下游接受程度相对较低，试探性涨价无法有效改善其经营状况。相反，在市场需求相对疲软 的情况下，价格上涨反而抑制了一部分下游采购需求，行业产销压力增大。 国庆假期结束后，预计全国纯碱产量继续保持在较高水平，一方面是因为行业开工率普遍较高，另一方面是因为新建项目逐步 投产。事实上，自去年年初以来，我国纯碱行业就一直处于供大于求的局面，玻璃等主要终端消费领域的需求增长速度明显放 缓，进一步加剧了供大于求的局面。此外，全球贸易摩擦也为出口带来了不确定性，出口对需求的拉动作用减弱。在此背景 下，即使全行业短期内能够通过调整开工率等方式调节产量，但从长远角度来看，若不能从根本上改变结构性供需矛盾，就很 难实现真正的复苏。 图为国内纯碱周度库存 看向需求端，目前下游对纯碱的实际需求没有出现明显增长。国庆假期之前，许多工厂开始提前备货，一定程度上提振了纯碱 需求，但这些订单带来的提振效应将逐渐消退。另外，下游加工制造业的整体利润率偏低也是一个不容忽视的因素。当企业 ...
