工业硅：关注新疆环保事件发酵，多晶硅：反内卷核心标的，低买思路为主

Group 1: Investment Ratings - No investment rating information is provided in the report Group 2: Core Views - The report focuses on industrial silicon and polysilicon, suggesting a low - buying strategy for polysilicon as an anti - involution core target, and also calls attention to the fermentation of the Xinjiang environmental protection incident regarding industrial silicon [1][2] Group 3: Summary by Catalog Fundamental Tracking - Futures Market: For industrial silicon, Si2601's closing price was 8,805 yuan/ton, with a decrease of 105 yuan compared to T - 1. Its trading volume was 170,669 lots, and the open interest was 196,943 lots. For polysilicon, PS2601's closing price was 55,510 yuan/ton, down 1,405 yuan from T - 1, with a trading volume of 159,380 lots and an open interest of 97,991 lots [2] - Basis: Industrial silicon's spot premium (against East China Si5530) was +645 yuan/ton, while polysilicon's spot premium (against N - type re - investment) was - 3510 yuan/ton [2] - Prices: Xinjiang 99 silicon was priced at 8900 yuan/ton, Yunnan Si4210 at 10000 yuan/ton, and polysilicon - N - type re - investment material at 52300 yuan/ton [2] - Profits: Silicon factory profits for Xinjiang new - standard 553 were - 2464.5 yuan/ton, and for Yunnan new - standard 553 were - 3576 yuan/ton. Polysilicon enterprise profits were 7.7 yuan/kg [2] - Inventory: Industrial silicon's social inventory (including warehouse receipt inventory) was 55.8 million tons, enterprise inventory was 18.3 million tons, and industry inventory was 74.1 million tons. Polysilicon's factory inventory was 29.1 million tons [2] - Raw Material Costs: Silicon ore in Xinjiang was 320 yuan/ton, and in Yunnan was 270 yuan/ton. Other raw materials like washed coking coal, petroleum coke, electrodes also had corresponding prices [2] - Prices in Related Industries: In the polysilicon (photovoltaic) industry, silicon wafers (N - type - 210mm) were 1.48 yuan/piece, battery cells (TOPCon - 210mm) were 0.283 yuan/watt, etc. In the organic silicon industry, DMC was 13600 yuan/ton, and in the aluminum alloy industry, ADC12 was 21700 yuan/ton [2] - Profits in Related Industries: DMC enterprise profits were 1729 yuan/ton, and regenerative aluminum enterprise profits were - 390 yuan/ton [2] Macro and Industry News - On December 3rd, the Development and Reform Commission of Qinhuangdao, Hebei, released a public notice on the application for the third - batch project construction of wind and photovoltaic power generation in 2025. There were 7 projects in total, with a total scale of 782,500 kilowatts, including 4 wind power projects with a scale of 282,500 kilowatts and 3 photovoltaic projects with a scale of 500,000 kilowatts. Project owners included PetroChina, PowerChina, and other companies [2][4] Trend Intensity - The trend intensity of industrial silicon was 0, and that of polysilicon was also 0, indicating a neutral view [4]
