China Crustacean Import Demand Elasticity Analysis, 2013-2023

Monthly China import value and quantity data for crustacean aquatic products (HS 0306) from 2013 to 2023. The dataset documents import growth and market concentration dynamics, including market shares, CR4/CR8, and HHI, and provides elasticity estimates from an origin-differentiated LA/AIDS model. It was authored by Haiqing Zhang and last updated in June 2026.

Use Cases

• Estimating expenditure and price elasticities for major crustacean suppliers based on the described LA/AIDS model.
• Analyzing market concentration risk using documented HHI, CR4, and CR8 indices over the 2013-2023 period.
• Identifying potential substitute sourcing corridors for supply chain diversification based on reported compensated cross-price elasticities.
• Assessing the impact of quality and composition shifts on import demand using insights from product-type subsamples mentioned in the description.

Strengths

• Provides specific import volume and value figures, showing growth from 0.089 million tons and USD 0.52 billion in 2013 to 1.24 million tons and USD 9.57 billion in 2023.
• Includes concrete concentration metrics, with the HHI increasing from 1,623 to 3,350 over the study period.
• Reports specific elasticity estimates for key suppliers, such as Ecuador's expenditure elasticity of approximately 1.9.
• Describes multiple robustness checks performed, including alternative price-index construction and subsample analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX document (46.6 KB), suggesting the underlying data tables may be embedded in a report format rather than a standalone structured file.
