摘要：Researchers have extensively studied crop yield response to weather variations, while only alimited number of studies have attempted to identify spatial heterogeneity in this relationship.We explore spatial heterogeneity in corn yield response to weather by combining geographicallyweighted regression and panel regression. We find that temperature tends to have negativeeffects on U.S. corn yields in warmer regions and positive effects in cooler regions, with spatialheterogeneity at a fine scale. The spatial pattern of precipitation effects is more complicated. Afurther analysis shows that precipitation effects are sensitive to the existence of irrigation systems.
