On the news front, the 18th issue of Qiushi magazine published on September 16 mentioned: efforts to address disorderly low-price competition among enterprises. Areas severely affected by "involution" should be effectively governed according to laws and regulations. Better leverage the self-regulatory role of industry associations to guide enterprises in improving product quality and promoting orderly exit of backward capacity.

Additionally, the 2025 China Silicon Industry Conference recently opened in Baotou, with the theme "Technological Innovation Coordinated Green Transformation, Industry Self-discipline Assisting Harmonious Development."

Industrial Securities stated that the photovoltaic industry is at the forefront of "anti-involution" efforts, with the industry currently forming two basic approaches: "price increases" and "production limits."

Galaxy Securities noted that globally, photovoltaic growth remains steady in the long term. In the short term, the supply-demand imbalance in the industrial chain has persisted for years with continuous losses. The sector's capital base and fundamentals have clearly bottomed out. As one of the key domestic "anti-involution" industries under review, policy relief or technological iteration is expected to accelerate supply-side clearing, providing significant valuation recovery potential for the sector.
