<div class="prose prose-custom max-w-none">
|
||
<p>本次周期的根本驱动力是**成本颠覆**，而非需求爆发。</p>
|
||
<ol>
|
||
<li><strong>供给端革命</strong>：以远兴能源为首的天然碱矿大规模开发是核心变量。天然碱法成本仅<strong>~1000元/吨</strong>（远兴项目可低至<strong>550-600元/吨</strong>），远低于传统氨碱法（~1600-1750元/吨）和联碱法（~1300-1550元/吨）。巨大的成本优势使其具备在下行周期中“清洗”高成本产能的绝对能力。</li>
|
||
<li><strong>环保政策倒逼</strong>：氨碱法污染大、原料利用率低，在环保趋严背景下，产能未来大概率将面临收缩。政策对绿色工艺的倾斜将加速这一进程。</li>
