Inventory in Fundamental Analysis - The total inventory of domestic soda ash manufacturers is 171.13 tons, of which the inventory of heavy soda ash is 86.44 tons, and the inventory is at a high level in the same period of history [34]. Supply - Demand Balance Sheet in Fundamental Analysis - The supply - demand balance sheet from 2017 to 2024E shows that the effective capacity, production, apparent supply, and total demand of soda ash have all changed to varying degrees. In 2024E, the effective capacity is 3930 tons, the production is 3650 tons, the apparent supply is 3536 tons, and the total demand is 3379 tons, with a supply - demand difference of 157 tons [35]. Influencing Factors - **Positive factors**: The production capacity of downstream photovoltaic glass has increased, boosting the demand for soda ash [3]. - **Negative factors**: Since 2023, the production capacity of soda ash has expanded significantly, and there are still large production plans this year. The cold - repair of float glass in the heavy - soda downstream is at a high level, with a continuous decrease in daily melting volume and weak demand for soda ash. The full - scale escalation of Sino - US tariff conflicts may drag down the market due to macro - pessimistic sentiment [4].
