· 供应链分析
我理解你的观点是基于仅看中国国内市场，而未考虑西方AI的扩张。两点如下： 一是整体需求的极端增长。即使有6英寸磷化铟(InP)晶圆，超大规模云服务商(Hyperscaler)的需求仍将超过供应。因此，无论是否存在竞争性替代品，需求不会消失，但可能会分散到中国国内市场的竞争者中。 二是垂直整合。你提到了西方阵营的$DOWA，特别是磷化铟(InP)领域。$AXTI控制了全球绝大部分的InP供应。如果超大规模云服务商为保险起见直接高价采购，再转交给$COHR，那么这对住友电工(Sumitomo)来说问题更大。而AXT则从这两层瓶颈中受益。新耀/JFS进入供应链只是增加了参与者，并非末日景象。例如存储领域（SK海力士；MU，三星）。 当然，如果中国实施出口管制，我们仅看中国国内市场，上述观点可能失效。但总体而言，即使增加更多参与者，需求仍超过供应（例如COHR已满产）。
I can see that if you look at China domestic markets only but not western AI ramp. So two things: One is extreme ramp in general. Hyperscaler demand will always outstrip supply even with 6-inch InP wafers. So competitive alternative or not, demand doesn’t disappear but might get spread out through competitive alternatives in China’s domestic market. The other is vertical integration. You mentioned $DOWA on the western side and especially InP. $AXTI controls a huge percent of the world’s InP supply and if those prices gets jacked up from hyperscaler buying direct for insurance-> handing them to $COHR, then it’s more of an issue for Sumitomo. And AXT benefits from both layers of the bottlenecks. Xinyao/JFS entering the supply chain just makes adds one more player to the equation so it’s not doom and gloom. Eg memory (sk Hynix; MU, Samsung) Of course these points might get thrown out the drain if China export controls and we’re looking at China domestic market only. But generally demand outstrips supply (eg. COHR is at max) even if we add in more players.
