1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views Natural Rubber - Supply in Southeast Asian producing areas is affected by heavy rainfall, but there is an expectation of increased supply after the rainy season, and raw material pressure may gradually emerge. Demand from tire enterprises is in a state of restorative improvement, but tire factory inventories have resumed accumulating, with significant inventory pressure on semi - steel tires. It is expected that rubber prices will mainly fluctuate weakly, and previous short positions should be held. Attention should be paid to the performance at the 14,000 level [1]. Industrial Silicon - The industrial silicon fundamentals continue to face pressure from high supply and high warehouse receipts. The spot price in East China has continued to decline by 50 - 100 yuan/ton, while the price in Xinjiang has stabilized. With an expected increase in supply, the price of industrial silicon futures SI2507 has decreased by 305 yuan/ton to 7,610 yuan/ton. The supply side is expected to grow despite weak demand, mainly due to the resumption of production of small enterprises in Southwest China, the commissioning of new production capacities, and the resumption of production of large enterprises. The main demand, the photovoltaic industry chain, continues to weaken, but the organic silicon industry shows some signs of improvement. With limited demand growth, declining raw material costs, and an expected increase in production, the fundamentals remain bearish, and prices are still under pressure [3]. Polysilicon - The spot price of polysilicon is gradually stabilizing, but the far - month futures price has dropped significantly due to the decline in the price of raw material industrial silicon and the expected increase in supply. The price of PS2507 has decreased by 1,205 yuan/ton to 34,885 yuan/ton, a decline of over 3%. Some polysilicon enterprises are resuming production in conjunction with capacity replacement or are still in the commissioning phase. The 06 contract is relatively firm as the first delivery is approaching in June, with a position of about 14,000 lots and no increase in warehouse receipts, which remain at 470 lots. Technically, the polysilicon futures price is still under pressure, and attention should be paid to changes in polysilicon production [5]. Glass and Soda Ash - **Soda Ash**: Despite the negative pressure of the commissioning of Lianyungang Alkali Industry last week, it will take time to produce products. The recent production decline due to maintenance is significant, and there is a strong expectation of maintenance in June. Therefore, the downward trend in the futures market has slowed. Considering short - term supply changes, it is more likely that inventories will remain stable. Fundamentally, the resumption of production in the photovoltaic industry has brought some demand for soda ash, but the overall demand has not increased significantly due to the stable and slightly decreasing float glass production capacity. In the medium - to - long term, there is still pressure for inventory accumulation after the maintenance period ends. From May to June, the implementation of maintenance can be monitored. If maintenance occurs, it will be beneficial for the June - July contracts. Short - term operations can involve short - selling on rebounds for far - month contracts, and calendar spreads between July and September can be considered [6]. - **Glass**: The spot market for glass is performing poorly, and market sentiment remains pessimistic. This week, the spot price of glass has mainly continued to weaken, with widespread price cuts in various regions. During the decline in the futures market, spot - futures traders have mainly sold, affecting the production and sales rate of manufacturers. From April to May, downstream deep - processing orders have gradually improved, and the demand from processing plants has seasonally recovered, leading to a phased improvement in glass supply and demand. However, market expectations are poor, with an expected slowdown in demand after June due to the summer rainy season. The actual fundamentals have marginally improved, but expectations and sentiment are moderately bearish. It is expected that the short - term glass price will continue to be under pressure and will operate weakly with fluctuations. Attention should be paid to whether the 09 contract can break through the 1,000 level, as a breakthrough may lead to further decline [6]. 3.

Core Viewpoint - The article emphasizes the need for "anti-involution" measures in various industries due to increasing competition and supply-demand imbalances, particularly in the context of government policies aimed at fostering a more sustainable and efficient market environment [1][2][20]. Group 1: Reasons for Emphasizing "Anti-Involution" - The industrial sector in China is facing significant supply-demand imbalances, highlighted by a decline in capacity utilization and persistent negative growth in the Producer Price Index (PPI), which has been negative for 31 consecutive months as of April 2025 [2][8]. - Capacity utilization rates have dropped from 77.7% in Q3 2021 to 75.1% in Q1 2025, indicating underutilization of resources [2][8]. - Local governments are increasingly competing for investment, leading to "involution" in certain sectors, characterized by concentrated efforts in similar industries, aggressive policy competition, and a lack of sustainable project management mechanisms [2][14]. Group 2: Industries with Potential "Involution" Competition - The focus of the "anti-involution" policy is on four key industries: photovoltaic, e-commerce, automotive, and steel, with measures including industry regulations, anti-monopoly enforcement, and capacity adjustments [3][22]. - Based on data indicators, industries such as black metal smelting, electrical machinery, and non-metallic products are identified as having a high degree of "involution" competition due to low capacity utilization and negative PPI growth [4][24]. - Other industries potentially affected include coal mining, automotive manufacturing, chemical raw materials, and pharmaceutical manufacturing, which exhibit similar characteristics of "involution" [4][47]. Group 3: New Aspects of the Current "Anti-Involution" Measures - The current round of "anti-involution" emphasizes industry self-discipline and market mechanisms, contrasting with previous supply-side reforms that focused primarily on traditional heavy industries [5][49]. - There is a stronger emphasis on regional collaboration and technological upgrades, aiming to create a differentiated and complementary industrial development structure while promoting high-quality growth [6][49]. - The government aims to eliminate outdated capacity and improve inefficient production through targeted policies that leverage digital and green technologies [6][49].
