记者丨曹恩惠 编辑丨张伟贤 实际上，多晶硅环节为了整治"内卷式"竞争，正在推进"收储"计划，即通过部分头部企业共同 出资收购除此之外的剩余产能，来强有力地推进产能整合。 就本周表现而言，价格小幅上涨的背后，多晶硅成交相对集中。硅业分会指出，本周多晶硅签 单企业数量维持在4—5家，且大多数成交量集中在头部两家企业，其余企业少量成交。而导致 价格小幅上升的主要原因，在于下游硅片价格回升，部分硅片企业库存压力减少，对上游硅料 价格提升的呈现一定的接受度。 但与前几周相比，本周多晶硅价格涨幅明显收窄。对此，硅业分会认为，主要对于当前的硅料 企业报价，绝大多数企业尚未实现规模性成交。 换言之， 当前多晶硅价格的反弹并未代表硅料需求实质性回暖。 目前，前期积压的库存仍是影响多晶硅价格走势的最大变量。根据硅业分会统计，7月份，国 内多晶硅产品约10.78万吨，前7个月累计产量70.49万吨，同比减少41.5%。这其中，在7月 份，出现了1家企业产能归零的情况，且根据各家企业排产安排，预计8月国内多晶硅产量约 12.5万吨。 若产能整合如期落地，硅业分会预测国内多晶硅年产能将减少至230万吨。而根据中国光伏行 业协会发布的统 ...

Report Summary 1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints - For industrial silicon, recent price fluctuations are due to rising raw material coal prices and changes in supply - demand. The market is expected to remain volatile with a neutral stance on the single - side strategy [1][2][3]. - For polysilicon, the futures market is affected by the anti - involution policy in the photovoltaic industry, with a certain deviation from the spot fundamentals. There is a risk of chasing high prices, and the recommended strategy is to sell - hedge at high prices and buy put options [4][6][7]. 3. Summary by Related Catalogs Industrial Silicon - **Market Analysis** - On July 30, 2025, the industrial silicon futures price rose. The main contract 2509 opened at 9500 yuan/ton and closed at 9285 yuan/ton, a change of 200 yuan/ton (2.20%) from the previous settlement.

The price of East China oxygen - passing 553 silicon was 9900 - 10100 (200) yuan/ton; 421 silicon was 10100 - 10400 (100) yuan/ton. Silicon prices in multiple regions such as Kunming, Huangpu Port, and Xinjiang also rose, while the price of 97 silicon remained stable [1]. - Affected by the rising price of raw material coal, the cost of silicon coal was strongly supported, driving up the prices of silicon coal in many regions. For example, the price of non - caking silicon coal in Xinjiang increased by 50 yuan/ton, and in Ningxia and Inner Mongolia, it increased by 40 yuan/ton [2]. - The consumption side: The quoted price of silicone DMC was 12100 - 12700 (- 50) yuan/ton. The supply in the silicone market was contracting, and manufacturers' willingness to maintain prices increased significantly [2]. - **Strategy** - The recent market fluctuations have increased, but the fundamentals have changed little. It is expected that the market will remain volatile. - Single - side: Neutral; Cross - period: None; Cross - variety: None; Spot - futures: None; Options: None [3]. Polysilicon - **Market Analysis** - On July 30, 2025, the main contract 2509 of polysilicon futures rose significantly, opening at 51,800 yuan/ton and closing at 54,705 yuan/ton, a change of 8.87% from the previous trading day. The position of the main contract reached 164,490 lots (140,638 lots the previous day), and the trading volume was 565,243 lots [4]. - The spot price of polysilicon remained stable. N - type material was 44.00 - 49.00 (0.00) yuan/kg, and n - type granular silicon was 43.00 - 46.00 (0.00) yuan/kg [4]. - Polysilicon manufacturers' inventory decreased, while silicon wafer inventory increased. The latest polysilicon inventory was 24.30, a month - on - month change of - 2.41%, and the silicon wafer inventory was 17.87GW, a month - on - month change of 11.55%. The weekly polysilicon output was 25,500.00 tons, a month - on - month change of 10.87%, and the silicon wafer output was 11.20GW, a month - on - month change of 0.90% [4]. - In terms of silicon wafers, domestic N - type 18Xmm silicon wafers were 1.20 (0.05) yuan/piece, N - type 210mm were 1.55 (0.05) yuan/piece, and N - type 210R silicon wafers were 1.35 (0.05) yuan/piece [4]. - For battery cells, the price of high - efficiency PERC182 battery cells was 0.27 (0.00) yuan/W; PERC210 battery cells were about 0.28 (0.00) yuan/W; TopconM10 battery cells were about 0.29 (0.00) yuan/W; Topcon G12 battery cells were 0.28 (0.00) yuan/W; Topcon210RN battery cells were 0.28 (0.00) yuan/W; HJT210 half - piece battery cells were 0.37 (0.00) yuan/W [5]. - For components, the mainstream transaction price of PERC182mm was 0.67 - 0.74 (0.00) yuan/W, PERC210mm was 0.69 - 0.73 (0.00) yuan/W, N - type 182mm was 0.68 - 0.69 (- 0.01) yuan/W, and N - type 210mm was 0.68 - 0.69 (- 0.01) yuan/W [5]. - According to the data released by the Silicon Industry Association, the transaction price range of polysilicon n - type re - feeding materials this week was 45,000 - 49,000 yuan/ton, with an average transaction price of 47,100 yuan/ton, a week - on - week increase of 0.64%. The transaction price range of n - type granular silicon was 44,000 - 45,000 yuan/ton, with an average transaction price of 44,300 yuan/ton, a week - on - week increase of 0.68% [6]. - From the perspective of supply and demand, the total polysilicon output in July is expected to be close to 110,000 tons, and there is still a large possibility of growth in August. In July, the start - up of silicon wafer factories was relatively weak. With the rise in silicon wafer prices, some enterprises had preliminary plans to start furnaces, and the implementation needs further observation. The supply - demand fundamentals were weak [6]. - According to the exchange announcement, non - futures company members or customers' single - day opening volume on the polysilicon futures PS2509 contract should not exceed 500 lots, and on the PS2510, PS2511, PS2512, and PS2601 contracts, it should not exceed 2,000 lots respectively [6]. - **Strategy** - Currently, the polysilicon futures market is mainly affected by the anti - involution policy in the photovoltaic industry, and there is a certain deviation from the spot fundamentals in the short term. The industry's acquisition and merger plan is still being promoted, and there is no clear conclusion yet. The futures are easily affected by news. From a valuation perspective, a price of 55,000 - 60,000 yuan/ton already gives the industry good profits, and the risk of chasing high prices is relatively large. The market fluctuations are large, and the futures position is large. After the exchange's position limit, the change in position can also easily cause market fluctuations. Investors need to pay attention to risk management. - Single - side: Sell - hedge at high prices; Cross - period: None; Cross - variety: None; Spot - futures: None; Options: Buy put options [6][7].
