Investment Rating - The industry investment rating is "Outperform the Market" (maintained) [2] Core Viewpoints - The report highlights that the closure of Dow's UK plant, which has a capacity of 145,000 tons, is part of a strategy to optimize European assets and focus on high-value derivatives, signaling a potential marginal improvement in the organic silicon industry [6] - The report anticipates that the exit of overseas capacity will lead to an increase in the prices of organic silicon base materials, alleviating some of the downward price pressure caused by global overcapacity [6] - The report notes that the domestic manufacturers with better cost control are likely to benefit from the demand shift due to the closure of overseas plants [6] - The report emphasizes that the organic silicon industry is entering a phase of supply-side pressure relief, with a significant increase in production capacity expected in 2024, but the lack of large-scale new capacity following this period may lead to improved supply dynamics [6] - The report indicates that the domestic demand for organic silicon is expected to grow steadily, driven by increased penetration in emerging fields such as electronics, new energy vehicles, and photovoltaic cells [6] - The report also highlights that China's exports of polysiloxane are projected to reach approximately 80,000 tons in 2024, reflecting a significant growth opportunity as overseas demand remains strong [6] Summary by Sections Market Performance - The report provides a comparative performance analysis showing a range of market movements from -15% to +29% for the basic chemical sector against the CSI 300 index from July 2024 to July 2025 [3] Related Research - The report references several related studies that discuss trends in deep-sea technology, policy impacts on capacity overcapacity, and the recovery of demand for light initiators, indicating a broader context for the organic silicon market [4] Investment Recommendations - The report suggests focusing on companies such as Hoshine Silicon Industry, Xin'an Chemical, Xingfa Group, Dongyue Silicon Materials, and Sanyou Chemical as potential investment opportunities [5]

光伏行业当前的供需情况呈现出明显的割裂状态。从需求端来看，电力投资企 业在电价和电量不确定的前提下趋于谨慎，导致下游装机增长存在疑问。虽然 难以得出明确结论，但市场需要时间来验证未来能否维持高增长。而从供给端 来看，产能过剩已成为共识。硅料作为光伏产业链中的关键环节，其产量决定 了下游产能的实际规模。如果硅料供应不足，下游产能将无法充分发挥。此外， 组件价格也受到政策干预，通过锁定成本价格来支撑上游环节。这种双重干预 使得市场表现出冰火两重天的状态。 政策对光伏行业有何影响？ 政策对光伏行业产生了显著影响。首先，通过计划经济手段干预市场，以加速 产能出清并决定哪些主体能够留存。例如，136 号文具有划时代意义，它使得 未来电力投资企业的电价发生变化，并呈下降趋势。同时，通过政策干预，希 望以组件为代表的新规产业链环节能够实现盈利，从而快速完成供给侧改革。 然而，这种政策之间双手互搏的情况导致市场出现割裂，一方面要求度电成本 更低，另一方面要求系统成本更高。这种矛盾使得市场处于前所未有的不确定 状态。 硅料产业专家交流 20250710 摘要 光伏行业正经历政策与市场双重干预，一方面通过计划经济手段加速产 能出 ...

Group 1 - The photovoltaic industry chain is experiencing price increases, with polysilicon manufacturers raising prices to a range of 45,000 to 50,000 yuan per ton, although actual transactions at this level have not yet been observed [1] - There is a strong determination among polysilicon manufacturers to maintain prices, and some downstream companies may accept slight price increases to avoid future risks of further price hikes [1] - The macro-level supply-side clearing guidance is expected to provide a framework for the industry's "anti-involution," but actual implementation may take time [1] Group 2 - Zhongyuan Securities suggests focusing on "capacity clearing" and "new technology iteration" as two main lines for investment [2] - In terms of capacity clearing, attention should be paid to leading companies in the polysilicon and photovoltaic glass sectors, particularly those with significant losses and clear capacity clearing expectations [2] - New technology advancements, particularly in BC cells and perovskite cell commercial applications, are also highlighted as areas of interest [2]

Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core Viewpoints of the Report - On July 9th, polysilicon showed a volatile and upward trend, with the main contract 2508 closing at 39,270 yuan/ton, an intraday increase of 5.03%, and the position increasing by 13,360 lots to 97,187 lots. The SMM polysilicon N-type silicon material price rose to 40,000 yuan/ton, and the price of the lowest deliverable N-type silicon material also rose to 40,000 yuan/ton. The spot premium over the main contract widened to 730 yuan/ton. Industrial silicon showed a volatile and downward trend, with the main contract 2509 closing at 8,140 yuan/ton, an intraday decrease of 0.67%, and the position increasing by 11,907 lots to 399,000 lots. The Baichuan industrial silicon spot reference price remained stable at 8,777 yuan/ton compared to the previous trading day. The price of the lowest deliverable 421 rose to 8,250 yuan/ton, and the spot premium narrowed to 90 yuan/ton [2]. - The polysilicon market is expected to gradually clear its production capacity through measures such as cost investigation and pricing, cancellation of planned restarts, state reserve purchases, the industry association setting a benchmark cost price, and re - positioning photovoltaics as an energy product rather than a manufacturing product. Currently, the trading logic of polysilicon is in a period of policy regulation and the fermentation of various news, and the expectation of anti - involution production cuts in the industry is accelerating. The market volatility has increased, and there is strong overall support. It is not advisable to short against the trend, and one can choose to wait and see or try to go long with a light position. For industrial silicon, although the warehouse receipts have decreased, the accumulation of social inventory suppresses the rebound space, so a high - selling strategy should be adopted. Attention should be paid to the implementation of production cuts for both types of silicon and the opportunity to go long on polysilicon and short on industrial silicon after the PS/SI price ratio rebounds [2]. Group 3: Summary by Relevant Catalogs 1. Research Viewpoints - Polysilicon and industrial silicon showed different trends on July 9th.
