破局与重构——建筑材料行业上市公司中期报告投研分析

Core Insights - The construction materials sector is experiencing significant structural differentiation, with varying performance across sub-industries, driven by factors such as real estate adjustments and demand contraction [1][2][6][19]. Overall Industry Performance - Since 2022, the SW construction materials index has underperformed compared to the CSI 300 due to adjustments in the real estate supply chain and demand shrinkage [2]. - In the first half of 2025, the total market capitalization of listed companies in the SW construction materials sector reached 862.68 billion yuan, with operating revenue of 690.43 billion yuan, a year-on-year decline of 4.92%, and a net profit attributable to shareholders of 21.69 billion yuan, a year-on-year increase of 43.58% [2]. Sub-Industry Analysis Cement Manufacturing - The cement manufacturing sector is in a severe downturn, with a three-year CAGR of -28.35% for total revenue and -77.85% for net profit, indicating a significant mismatch between high supply and weak demand [10][11]. - The national cement capacity utilization rate was only 55.8% in the first half of 2025, well below the 75% threshold for reasonable operation [10]. Cement Products - The cement products sector shows a contrasting performance with a three-year CAGR of -15.58% for revenue and -152.26% for net profit, but a gross margin of 25.67% and a high inventory turnover rate of 7.99 times [12]. - The sector benefits from new infrastructure and major engineering investments, supporting demand for cement products [12][13]. Glass Fiber Manufacturing - Glass fiber manufacturing is the only sub-industry showing positive growth across all dimensions, with a three-year CAGR of 18.72% for revenue and 23.47% for net profit [14]. - The growth is driven by expanding downstream demand in sectors like wind power and photovoltaics, supported by favorable industrial policies [14]. Glass Manufacturing - The glass manufacturing sector has reported an overall loss for the first time, with a three-year CAGR of -10.23% for revenue and -35.87% for net profit, facing challenges from overcapacity and strict environmental regulations [15]. Refractory Materials - The refractory materials sector remains relatively stable, with a three-year CAGR of -1.87% for revenue and -15.62% for net profit, benefiting from rigid demand in high-energy-consuming industries [16]. Pipe Materials - The pipe materials sector is driven by infrastructure investments, with a three-year CAGR of -5.67% for revenue and -12.35% for net profit, but a gross margin of 22.45% [17]. Other Construction Materials - The other construction materials sector, covering gypsum boards, artificial boards, and decorative materials, shows strong anti-cyclical properties due to its low correlation with real estate [18]. Investment Value and Strategy - The report suggests focusing on three core investment tracks: high-growth manufacturing represented by glass fiber, high-turnover engineering products like cement products, and comprehensive service transformations in waterproofing and decoration [19][20]. - Emphasis is placed on selecting industry leaders with strong cash flow and balance sheet quality, advocating for a diversified cross-sector allocation to mitigate cyclical risks [20]. Future Outlook - The construction materials industry is expected to shift from quantity competition to quality competition, with increasing concentration as a trend [22]. - New infrastructure investments and green building initiatives are projected to become significant growth drivers, with a planned investment of 1.5 trillion yuan in new infrastructure by 2025 [22].
