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.
