生猪产能传导链条及价格传导机制再复盘

Group 1: Core Logic of the Pig Cycle - The core logic chain of changes in the breeding sow inventory is summarized as: breeding profit fluctuations → capacity adjustment decisions (restocking/elimination) → changes in breeding sow inventory → piglet supply → future adjustments in pig supply → cyclical price fluctuations [2][3] - The essence of the pig cycle is the lagged transmission between breeding sow inventory and pig prices, rooted in the long production cycle characteristics and supply-demand mismatches [3][4] Group 2: Theoretical Lag and Practical Verification - The complete production chain from restocking breeding sows to market pigs takes 10-13 months, with significant negative correlation (r=-0.75) between breeding sow inventory and pig prices 13 months later [5][6] - Historical data shows that each round of breeding sow reduction is typically over 8%, which is sufficient to support a new price increase cycle [8] Group 3: 2025 Pig Production Capacity Outlook - As of January 2025, the national breeding sow inventory is 40.62 million heads, slightly down month-on-month but up 0.8% year-on-year, exceeding the normal inventory level [10] - The main trend for 2025 is expected to be simultaneous capacity expansion and structural adjustment, with leading companies continuing to increase output while low-efficiency capacity is being eliminated [10][11]
