A Biophysical Model of Corn Yield: Integrating Climatic and Social Determinants
构建了一个同时考虑气候和社会因素的玉米产量模型，气候变量按物候阶段设定，社会因素包括市场、技术、规模和政策，可用于评估气候变化的影响与适应。
Abstract We estimate a model that accounts for both climatic and social determinants of corn yield in the United States. Climate variables are specified for periods that correspond to phenological stages of development. Social determinants include market conditions, technical factors, scale of production, and the policy environment. The model accounts for the historical and cross‐sectional variation in yield, and the interpretation of coefficients is consistent with independent analyses of the climatic and social determinants. The hybrid model provides a framework for assessing the effect of, and adaptation to, climate change.
