Description
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.

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
