我一直坚信，PEM制氢不仅是最适配风光电波动性的技术路径，也将在平准化氢气成本（LCOH）上展现出最终竞争力。就像DeepSeek在算力红海中通过底层算法重构杀出重围一样，枡水科技正在做的是氢能领域的“材料重构”，用全自主产业链的闭环能力，为绿氢平价时代铺平最后一段路。
We explore this further in three ways in the Appendix. First, we ask whether the percentile cutoff that we use to define treatment matters, varying it from the median to the 95th percentile. In all cases, the impact is flat or negative (meaning that unemployment decreases for the exposed group). Next, we focus on young workers in particular, those aged 22 to 25 as in Brynjolfsson et al. (2025). Finally, we use data on unemployment insurance claimants from the Department of Labor to measure the unemployment, rather than CPS survey responses.
