Chemical Industry Insights - CITIC Securities indicated that the chemical industry's capital expenditure continues to weaken year-on-year, but the profitability of chemical enterprises is expected to gradually bottom out and recover under the backdrop of ongoing anti-involution efforts. The investment value of the chemical sector is anticipated to continue improving by 2026. Investment strategies suggested include focusing on high-energy-consuming products such as calcium carbide, caustic soda, and yellow phosphorus, which may become effective tools for anti-involution. Additionally, attention should be given to segments where self-discipline is steadily advancing, products that have fallen below or are close to cash cost lines, and chemical products driven by new demand or strong downstream demand with price increase potential [2]. Trade and Material Substitution - According to Open Source Securities, the Ministry of Commerce has initiated anti-dumping investigations against Japan, particularly concerning high-end membrane materials. Announcements made on January 6 and 7 included prohibiting the export of dual-use items to Japanese military users and launching anti-dumping investigations on imported dichlorodihydrosilane from Japan. As the global touch module, LCD/OLED display panel, and MLCC ceramic capacitor industries shift to mainland China and domestic manufacturers expand capacity, there is an urgent need for the domestic optoelectronic industry to break Japan's technological monopoly on high-end raw materials and achieve localization of critical raw material supply [3]. Chatbot Commercialization - CICC reported that the current monetization of overseas chatbots primarily relies on subscriptions, while domestic models are mostly free. In the long term, as the cost of unit reasoning decreases, a "free + transaction-oriented effect advertising" model is expected to emerge, which could lower barriers to entry and increase the ceiling in the ToC Agent field. Internet advertising leaders possess advantages in data and infrastructure dimensions [4].
