County-Level Grain Productivity and Climate Data for China, 1998-2022

Tong Wang's dataset provides panel data for 334 counties across 13 major grain-producing provinces in China from 1998 to 2022. It likely contains variables for climate metrics, grain productivity, and financial institution distribution. The data was last updated on March 19, 2026.

Use Cases

• Modeling nonlinear relationships between temperature/precipitation and grain productivity based on climate variables.
• Analyzing the moderating effect of credit access on climate impacts based on financial institution distribution.
• Investigating mechanisms like agricultural mechanization and irrigation capacity as pathways for climate resilience.
• Conducting panel regression analysis on county-level agricultural performance over a 25-year period.

Strengths

• Data covers 334 counties over a 25-year period (1998-2022).
• Focuses on 13 major grain-producing provinces in China.
• Analysis employs a two-way fixed effects panel regression model and 2SLS approach.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
