2025H1化工整体业绩同比修复，关注“反内卷”带来的供给弹性及科技新趋势下的国产化需求

Core Insights - The overall performance of the Shenwan basic chemical sector showed year-on-year recovery in the first half of 2025, with total operating revenue reaching 1,124.03 billion yuan, up 3.02% year-on-year, and net profit attributable to shareholders of 69.72 billion yuan, up 4.43% year-on-year [1][2]. Revenue and Profit Growth - The sectors with the highest revenue growth include fluorochemicals, modified plastics, civil explosives, other chemical raw materials, and adhesives and tapes [1][2]. - The sectors with the highest net profit growth include pesticides, fluorochemicals, potassium fertilizers, food and feed additives, and adhesives and tapes [1][2]. Underperforming Sectors - The sectors that faced significant performance pressure in the first half of 2025 include organic silicon, viscose, soda ash, and nylon inorganic salts [2]. Market Trends and Data - During the week of August 25 to August 29, 2025, the Shanghai and Shenzhen 300 Index rose by 2.71%, while the Shenwan petrochemical index fell by 0.57%, underperforming the market by 3.28 percentage points. The Shenwan basic chemical index increased by 1.11%, also underperforming the market by 1.60 percentage points [4]. - The top five sectors by growth were fluorochemicals (8.35%), nitrogen fertilizers (6.17%), coal chemicals (5.59%), compound fertilizers (3.14%), and pesticides (2.01%). The sectors with the largest declines included other rubber products (-5.00%), coatings and inks (-3.64%), viscose (-3.28%), oilfield services (-3.11%), and carbon black (-2.99%) [4]. Price Trends - The price increases for the week included methyl acrylate (4.73%), nitric acid (4.32%), caustic soda (3.80%), butyl acrylate (2.46%), and formaldehyde (2.25%).

Investment Recommendations - The supply side is expected to undergo structural optimization, with a focus on sectors with elasticity and advantages. The domestic policy environment frequently emphasizes supply-side requirements, while overseas chemical companies are experiencing shutdowns and capacity exits due to rising raw material costs and Asian capacity impacts [6]. - In the short term, geopolitical tensions may increase uncertainty in overseas chemical supply. However, China's chemical industry has a clear competitive advantage, with significant cost advantages and technological breakthroughs, positioning it to reshape the global chemical industry landscape [6]. - Recommended sectors include organic silicon, membrane materials, chlorine-alkali, and dyes, with key companies such as Hoshine Silicon Industry, Xingfa Group, Dongcai Technology, Junzheng Group, Zhejiang Longsheng, and Runtu Co. [6]. - The food additives industry is expected to expand due to new consumption trends and regulatory support, with a focus on companies that emphasize technology and product differentiation, such as Bailong Chuangyuan and Jinhwa Industrial [7]. - The domestic self-sufficiency rate for new chemical materials is approximately 56%, indicating a significant opportunity for domestic substitution, particularly in semiconductor materials and high-end engineering plastics [7].
