China Maize Industry Security Composite Index, 2011–2020

12 indicators across supply, market, technology, and environment were synthesized to construct a composite Maize Industry Security Index for China from 2011 to 2020. The index, created by Jian Wang and shared under CC-BY-4.0, peaked at 97.33 in 2017 and eased to 91.79 by 2020, indicating a basically secure range with cyclical fluctuations.

Use Cases

• Analyze cyclical trends in agricultural market security based on the market operation sub-index.
• Model the relationship between technological innovation and industry resilience based on indicators like mechanization and variety approval.
• Assess the impact of resource-environment conditions on long-term production viability based on carbon-emissions intensity data.
• Evaluate policy effectiveness on basic security levels based on data spanning a decade of planting-structure adjustments.

Strengths

• Data spans a 10-year period from 2011 to 2020, providing a longitudinal view.
• Index construction involved 12 indicators aggregated into four distinct sub-indices with expert-assigned weights.
• Robustness checks were performed using alternative weighting and normalization approaches.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is provided as a 742.7 KB DOCX file, which may require extraction or conversion for analysis.
