Group 1: Report Industry Investment Rating - No information provided Group 2: Core View of the Report - Recent raw material butadiene prices have been rising due to strong demand and unexpected shutdowns of some units, significantly increasing the production cost of cis - butadiene rubber. Driven by macro - positive news, the spot market price has strengthened, and the inventories of production and trading enterprises have decreased to varying degrees. However, some private cis - butadiene rubber plants are expected to restart, increasing supply. In terms of demand, the capacity utilization rate of domestic tire enterprises increased significantly last week, but most semi - steel tire enterprises have slow overall shipments and continued inventory growth, while full - steel tire capacity utilization is in a restorative growth state, with some enterprises facing increased shipment pressure, continued growth in finished product inventory, insufficient orders, and overall production scheduling lower than the pre - holiday average.
