兴业研究：“反内卷”对PPI回升的影响测度

Core Viewpoint - The "anti-involution" policy is expected to positively impact the Producer Price Index (PPI) by increasing capacity utilization in key industries, particularly in raw materials like coal and chemicals, while the automotive sector shows a more muted response [1][2][3]. Group 1: Impact of "Anti-Involution" on PPI - The "anti-involution" policy has led to a rebound in PPI, with a recorded year-on-year change of -2.3% in September 2025, narrowing the decline by 0.6 percentage points from the previous month [2]. - Key industries affected by the "anti-involution" include chemicals, coal mining, steel, non-metallic minerals, electrical machinery (photovoltaics), and automobiles, with most industries operating at historically low capacity utilization levels as of Q3 2025 [3][6]. - The estimated impact of increasing capacity utilization to historical percentiles shows that reaching 50% could raise PPI by 1.3 percentage points, while 75% could increase it by 1.9 percentage points, with the former scenario being more realistic given current demand conditions [8][9]. Group 2: Monitoring PPI Changes - To monitor the effects of "anti-involution" on PPI, high-frequency price data from key industries are used to fit PPI changes, allowing for real-time tracking of price movements [13][22]. - As of October 2023, most industrial prices in key sectors have declined compared to the previous month, with an overall estimated drag on PPI of 0.1 percentage points due to this price drop [22][24]. - Specific price changes in October include a decrease in PPI for black processing, chemicals, non-metallic minerals, and automotive manufacturing, while coal and photovoltaic prices have shown slight increases [22][24].
