东方雨虹 20250709 摘要 公司在去年下半年价格战后，试点提价策略，发现对销量影响不大，决 定逐步恢复价格，尤其在零售端防水涂料市场（占全国 70%份额）具有 较强议价能力，提价幅度最高达十几个百分点，瓷砖胶等基础材料也适 度上调。 工程市场竞争格局变化，头部企业如宇宏、科顺和北新防水不再内卷， 陆续发布涨价函，宇宏 3 月涨价函已落地，4 月价格止跌，二季度累计 价格环比一季度略有提升，预示行业平均利润率有望恢复。 工程市场需求下行，大量防水公司退出，从业企业数量大幅下降（估计 至少 60%），价格影响力集中于宇宏、科顺和北新防水三家，若三家不 再打价格战，调价落地可行性较高。 价格战导致防水行业质量下降，部分企业产品甚至无法达标五项基本检 测指标。强条在重点工程有效，但普通项目落地效果差，需加强监管， 避免牺牲质量换取市场份额的短视行为。 2025 年上半年，民建业务一季度收入下降十几个百分点，二季度恢复 双位数增长，预计全年增长；零售业务一、二季度均增长，优于工程市 场；工程市场降幅收窄，但价格基数低影响收入。 Q&A 东方雨虹近期防水产品的提价背景及其持续性如何？ 东方雨虹近期的防水产品提价主要 ...

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The scarcity of orbital spectrum drives competition, and the construction of domestic low - orbit constellations has entered an accelerated phase. With limited low - orbit space and spectrum resources and strict deployment time requirements from the ITU, competition for resource locking is intensifying. China is expected to see an accelerated launch of low - orbit satellites from 2025 - 2030. Representative constellations include "Guowang", "Qianfan", and "Honghu - 3". Shanghai Harbor, with its satellite energy system products, is expected to benefit from the accelerated development of low - orbit satellites [5]. - Leading waterproofing companies such as Yuhong, Beixin, and Keshu have raised prices on both civil construction and engineering products. In the context of the industry's "anti - involution", the collective price increase by leading enterprises may promote price recovery, but the degree of price repair remains to be seen due to weak demand [5]. - Investment suggestions include paying attention to companies like Honglu Steel Structure, China Jushi, Punan Co., Ltd., Hainan Huatie, Beixin Building Materials, China National Chemical Engineering, China State Construction, Shanghai Harbor, Sinoma Science & Technology, and Keda Manufacturing [5]. 3. Summary According to the Table of Contents 3.1 Week - Specific Topic: Orbital Spectrum Scarcity Drives Competition, and Domestic Low - Orbit Constellation Construction Enters an Accelerated Phase - **Satellite Orbit Types**: Communication satellite orbits are mainly divided into GEO, MEO, and LEO. LEO can reduce power attenuation and communication delay, simplify terminal design, and is suitable for multi - satellite networking. Compared with GEO, LEO/MEO has smaller delay, and satellites are smaller and lighter, facilitating multi - satellite launches and reducing constellation construction costs and cycles [5][7]. - **Resource Scarcity and Competition**: Low - orbit space and frequency spectrum resources are scarce. The total capacity of low - orbit satellites is about 60,000, and Starlink plans to send 42,000 satellites into low - orbit by 2027, accounting for about 70%. The L, S, C frequency bands are almost exhausted, and the Ku, Ka bands are difficult to coordinate. According to ITU rules, operators need to complete satellite deployment within a specified time to lock resources, intensifying competition [5][11]. - **Policy Support**: Since 2014, China has successively introduced policies to encourage private capital to participate in commercial space activities. In 2023, commercial space was included in strategic emerging industries, and it has been mentioned in the government work reports of 2024 and 2025, indicating strong policy support [16]. - **Global and Domestic Constellation Construction Status**: Globally, SpaceX leads in low - orbit constellation construction, with other countries' enterprises following. In China, constellations like "Guowang", "Qianfan", and "Honghu - 3" have formulated phased launch plans. Although the number of launches in 2024 did not meet expectations, the launch rhythm is expected to accelerate from the second half of 2025 [5][17][23]. 3.2 Profit Forecast and Valuation of Main Covered Companies The report provides profit forecasts, valuations, and investment ratings for multiple companies, including Hainan Huatie, Punan Co., Ltd., China Jushi, etc. EPS, P/E, P/B, and other indicators for 2024 - 2027 are presented, and most investment ratings are maintained [33]. 3.3 Weekly Market Review - **Industry Index Performance**: In the week from June 28th to July 4th, 2025, the building and building materials industries showed certain fluctuations. Among building sub - sectors, the garden engineering index had the highest increase at 2.20%, while among various industries, the steel index had a relatively large decline [38][40]. - **Infrastructure Public REITs Performance**: The report lists the closing prices, 52 - week highs and lows, weekly, monthly, year - to - date, 250 - day, and IPO - since price changes of multiple infrastructure public REITs. The average weekly increase was 1.07%, the average monthly increase was 1.31%, and the average year - to - date increase was 20.99% [46][47]. 3.4 Aggregate Data Tracking - **Real Estate Data**: The report presents data on real estate new construction, construction, completion, sales area cumulative year - on - year growth, land transaction area, and real estate transaction data from 2022 - 2025 [49][58][68]. - **Social Financing Data**: Data on monthly new social financing, new RMB loans, new corporate bond financing, etc., from 2022 - 2025 are provided [78]. - **Infrastructure Investment Data**: The cumulative year - on - year growth rates of narrow - sense and broad - sense infrastructure investment, as well as investment in power, transportation, and water conservancy industries from 2022 - 2025, are shown. The new contract signing data of eight major construction central enterprises from 2022Q1 - 2025Q1 are also presented [88][94]. - **Special Bond Issuance Data**: Data on monthly and cumulative new and replacement special bond issuance from 2022 - 2025 are provided [96]. 3.5 High - Frequency Data Tracking - **Cement Data**: Information on national PO42.5 cement average price, East China regional cement price, cement - coal price difference index, cement capacity utilization rate, and cement production monthly year - on - year growth rate is presented [107][114]. - **Float Glass Data**: Data on glass spot price, futures price, inventory, and daily melting volume are provided [115][117][119][122]. - **Photovoltaic Glass Data**: Information on soda ash price, 2mm photovoltaic glass price, inventory, and daily melting volume is presented [122][123][125]. - **Glass Fiber Data**: Prices of SMC roving, winding direct roving, injection roving, G75 electronic yarn, and glass fiber inventory are shown [128][129][132][134][138]. - **Carbon Fiber Data**: Data on carbon fiber average price, raw silk price, inventory, production, capacity utilization rate, gross profit margin, cost, and gross profit are provided [135][139][142][146][148][151][152]. - **Magnesia and Alumina Price Data**: Prices of large - crystal fused magnesia and alumina are presented [153][156]. - **Upstream Raw Material Price Data**: Prices of asphalt, waste paper, PVC, and HDPE are shown [159][160][162][163]. - **Physical Workload Data**: Prices of titanium dioxide and acrylic acid, high - machine rental rate, excavator working hours, and asphalt average capacity utilization rate are presented [167][168][170][173].
