证券研究报告 工业/基础材料 本周观点：旺季基建或启动，特种电子布延续高景气 上周国务院全体会议强调努力完成全年经济社会发展目标任务，要求"加力 扩大有效投资，发挥重大工程引领带动作用"，叠加上周 PPP 存量项目规 范意见落地，新型政策性金融工具有望出台等，我们认为基建端有望旺季发 力。中材科技公布中报，特种电子布量价两旺，叠加上周玻纤产业论坛召开， 我们预计低膨胀布和石英纤维布有望延续高景气。上周工信部再次召开光伏 产业会议，我们认为光伏产业反内卷政策框架或初步建立，近期光伏玻璃已 开始大幅去库，2.0mm 光伏玻璃价格环比继续小幅提升，但盈利能力仍然 承压。短期继续重点推荐中报同比大幅增长的水泥玻纤板块，以及估值仍处 于低位的大建筑板块，重点推荐亚翔集成、中国中冶、中材国际、鸿路钢构、 三联虹普、三棵树、中材科技、华新水泥、上峰水泥、海螺创业。 上周细分行业回顾 截至 8.22，上周全国水泥价格周环比+0.7%；水泥出货率 45.7%，周环比/ 同比-0.1pct/-2.7pct。上周国内浮法玻璃均价 64 元/重量箱，周环比/同比 -0.6%/-14.6%，样本企业库存 5636 万重箱，周环比+0. ...

大宗建材方面：1、水泥：（1）八月下旬，受资金面持续紧张，以及部分地区仍有高 温、雨水天气影响，整体市场需求恢复较为缓慢，国内重点地区水泥企业平均出货率在 45.7%左右。价格方面，部分省份已陆续完成首轮提价，为巩固当前涨价成果，企业有意继 续推动价格上行。预计后续水泥价格将呈稳中偏强趋势运行。（2）行业供给自律共识有望 进一步强化，全年盈利中枢有望好于去年。尽管Q2因需求波动或错峰执行问题供需阶段性 失衡、价格出现回落，但今年行业在主导企业引领下维护利润的意愿显著增强，我们认为供 需再平衡时间仍然会明显好于去年，8月中下旬标志性市场或开启提价，节点有望较去年提 前，全年盈利中枢有望高于去年。（3）板块市净率估值处于历史底部，产业政策落地有望 推动盈利持续修复、估值回升。水泥企业市净率估值处于历史低位，板块分红比例提升。行 业景气低位为进一步的整合带来机遇。产能产量管控政策有望逐步落实，有望推动僵尸产能 退出，改善产能严重过剩区域的供给矛盾。水泥行业纳入全国碳市场，碳排放对供给的约束 趋严有望加速过剩产能出清和行业整合。（4）龙头企业综合竞争优势凸显，中长期有望受 益于行业格局优化，估值有望迎来修复，推荐全国 ...
