1. Report Industry Investment Rating No information provided in the content. 2. Core Viewpoints of the Report - This week, the total PVC production increased slightly, with the calcium carbide method increasing its load and the ethylene method decreasing its load. After the upstream ethylene reduces its load next week, the production of ethylene - based PVC will decrease, and the overall PVC production is expected to continue to decline [6]. - The export order volume has slightly recovered. In addition to tariff factors, the increase in PVC costs globally may lead to better - than - expected exports. Currently, the market generally believes that PVC has price competitive advantages even if the export tax rebate is cancelled [6]. - This week, the apparent demand has returned to normal levels, and the expected apparent demand for next week is calculated at 44.91 tons. The inventory decreased by 85,000 tons this week and is expected to continue to decline next week [6]. - The spot price of caustic soda fluctuated strongly, the price of calcium carbide increased this week, the price of semi - coke remained stable, and the price of ethylene increased significantly due to the reduction in the load of ethylene plants [7]. - The comprehensive profit of chlor - alkali has slightly improved. Attention should be paid to whether the production of ethylene - based PVC will be reduced [9]. - Upstream: The price of PVC and caustic soda has increased, and the comprehensive profit has improved. The production of calcium carbide - based PVC has increased, and the production of ethylene - based PVC may decline. Attention should be paid to the reduction in the load of upstream cracking units. Midstream: Traders mainly adopt the spot - futures arbitrage strategy, but the shipment situation has slightly deteriorated. The cancellation of warehouse receipts next week may put some pressure on the spot market. Downstream: The downstream operating rate is still weak, but there is a slight situation of stockpiling [10]. 3.

1. Report Industry Investment Rating No information provided in the content. 2. Core Viewpoints of the Report - The comprehensive profit of chlor - alkali integration has significantly recovered, while the profit of ethylene - based production is relatively low, and the current valuation is neutral. There are expectations of passive production cuts in ethylene - based production and seasonal maintenance, and the overall load in March is expected to decline. Although the domestic demand is under pressure, overseas demand may increase due to raw material shortages, and the market is expected to turn to destocking in March. In the short term, before the Iranian issue is resolved, the market will mainly show a rebound, but be cautious as the price has risen too much [11]. 3. Summary by Directory 3.1 Week - on - Week Assessment and Strategy Recommendation - **Cost and Profit**: The price of Wuhai calcium carbide is 2,550 yuan/ton, a week - on - week increase of 450 yuan; the price of Shandong calcium carbide is 2,910 yuan/ton, a week - on - week increase of 205 yuan; the price of medium - grade semi - coke in Shaanxi is 735 yuan/ton, unchanged week - on - week. The comprehensive profit of chlor - alkali integration has significantly recovered, while the profit of ethylene - based production is relatively low, and the current valuation is neutral [11]. - **Supply**: The PVC capacity utilization rate is 81.4%, a 0.2% increase month - on - month. Among them, the calcium carbide method is 82.9%, a 2.3% increase month - on - month; the ethylene method is 77.6%, a 4.6% decrease month - on - month. In March, some enterprises may start spring maintenance, and with the continued blockade of the Strait of Hormuz, the ethylene - based production load is expected to further decline, and the overall load is expected to decline [11]. - **Demand**: The export tax - rebate policy is planned to be cancelled on April 1st, and the short - term effect of rush - exporting has declined. However, due to the lack of raw materials in Asia, the load reduction in Northeast Asia may bring export growth opportunities. The start - up rates of the three major downstream industries are gradually recovering from the Spring Festival holiday. The load of pipes is 38%, a 5% increase month - on - month; the load of films is 60%, a 13% increase month - on - month; the load of profiles is 30%, a 2.6% increase month - on - month; the overall downstream load is 39.3%, a 3.5% increase month - on - month.
