|

<p class="text-gray-400">乙烷裂解是全球成本最低的乙烯生产工艺。路演数据显示，税前利润率可达40%-45%，单吨乙烯成本较石脑油路线低500-1000元。此优势源于乙烷作为美国天然气伴生物的低廉价值，其价格地板由天然气热值决定。</p>

|

<li><strong>中美贸易与出口政策：</strong>详细记录了美国对华乙烷出口从限制、逐步放宽到完全解除的全过程。限制曾导致6月出口中断，解除后已有8艘船只驶往中国，凸显了乙烷在中美贸易中的重要性。</li>
|
||
<li><strong>中国进口关税政策：</strong>2025年1月1日起，中国将乙烷进口暂定税率从2%下调至1%，并增列独立子目。此举被解读为国家对乙烷战略地位的肯定，并降低了龙头企业原料成本。</li>
|
||
<li><strong>企业项目动态：</strong>中油工程、中石化炼化工程等中标海外乙烷管道/裂解项目；中国船舶获全球首制15万方ULEC订单，凸显技术实力。</li>

<h3 class="text-xl font-bold text-white mb-4">路演纪要：基础设施瓶颈</h3>
|
||
<ul class="space-y-2 list-disc list-inside text-gray-400">
|
||
<li><strong>定价机制：</strong>乙烷价格与天然气热值价格强相关 (天然气价$/MMBtu × 50 ≈ 乙烷基准价)，但当出口设施不足时，过剩的乙烷价格可能跌破热值。</li>
|
||
<li><strong>出口设施瓶颈：</strong>美国乙烷出口码头、管道和专用船（VLEC）是核心瓶颈。2025年仅新增250万吨出口能力，卫星化学通过合资抢占先机，后发者（如万华）面临激烈竞争和更高的物流成本。</li>
|
||
<li><strong>长期供应过剩：</strong>美国乙烷产量随天然气持续增长，而本土消化能力饱和，大量乙烷被迫回注（re-injection），出口需求强烈。若出口设施增速跟不上产量，价格将长期承压。</li>

<h3 class="text-xl font-bold text-white mb-4">研报精粹：关税与盈利测算</h3>
|
||
<ul class="space-y-2 list-disc list-inside text-gray-400">
|
||
<li><strong>高度依赖美国进口：</strong>中国乙烷进口依赖度高达98.7%，来源单一。美国是全球主导的乙烷出口国，供应过剩趋势不改。</li>
|
||
<li><strong>关税影响量化：</strong>在10%关税下，乙烷进口成本增加约48美元/吨，导致乙烷裂解制乙烯加工利润减少约429元/吨。但即便如此，该路线仍可维持盈利。</li>
|
||
<li><strong>企业应对与机遇：</strong>企业可通过“来料加工”模式规避关税。万华化学等公司通过“丙烷改乙烷”技改项目，调整原料结构以降低成本，被视为低成本扩张标的。</li>
