造船观点回顾，2021 年9 月我们提出造船周期反转的逻辑，我们站在造船新一 轮周期2021-2038 的起点上：二战，1960-1973,1990-2010 是过去三轮造船大 周期，平均每20-30 年经历一轮大周期的原因为需求周期、船龄替代周期、环保 公约三大因素。上一轮交付高峰将于2021-2038 年开始进入替代周期。集中度上 升，竞争格局改善，十年技术迭代，中国船舶竞争力今非昔比，碳中和措施保证 长期订单持续性，资产整合，中国船舶实力大增。

当前军工板块的估值已接近2020 年第四个底部区间，高性价比更加凸显，建议坚定加大配置力度。2022 年初以来，中证军工指数下跌了19.44%，板块估值得到了充分消化，高性价比更加凸显。目前军工板块整体PE 为57.16 倍，处于历史低位。从我们跟踪的核心重点公司来看，目前军工板块对应2022 年预期的PE 为41.5 倍。2022 年上游、中游、下游的平均估值水平依次为33.7、36.8、58.8 倍，对应2022 年的PEG 水平分别为1.07、1.01、2.09。我们认为，当前军工板块正处于景气切换的关键节点，板块高性价比更加凸显，2023 年军工国改有望密集落地，板块估值有望实现切换，加配军工板块正当时。
