Feed Cost Shocks and Profitability Pressure in China's Hog Supply Chain, 2015-2025

Jinshuai Zhang's dataset contains monthly data from January 2015 to December 2025 used to analyze feed cost shocks and profitability pressure in China's hog supply chain. The data underpins a nonlinear autoregressive distributed lag (NARDL) model examining relationships between feed costs, piglet prices, and downstream hog-sector outcomes. The dataset was last updated on 2026-05-14.

Use Cases

• Modeling long-run relationships between feed costs and hog prices based on the described NARDL analysis.
• Analyzing producer profitability pressure based on the hog-to-feed ratio mentioned in the description.
• Investigating asymmetric pass-through of feed cost shocks to producer margins using the described rolling-window analysis.
• Assessing the role of piglet prices versus direct feed costs in hog-market dynamics as indicated in the findings.

Strengths

• Data spans a 10-year monthly time series from 2015 to 2025.
• Analysis employs a nonlinear autoregressive distributed lag (NARDL) model and cointegration tests as described.
• Dataset is licensed under CC-BY-4.0 for open use.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 12.1 KB file size suggests a limited scope of data.
