英文文献：Estimating the Effects of Weather Variations on Corn Yields using Geographically Weighted Panel Regression-利用地理加权面板回归估计天气变化对玉米产量的影响
英文文献作者：Cai, Ruohong,Yu, Danlin,Oppenheimer, Michael
英文文献摘要：
Through a geographically weighted panel regression analysis, we demonstrate the spatially varying relationship between weather and corn yields. A balanced panel data of 958 U.S. corn production counties for the period 2002-2006 is used. The results indicate that the relationship between weather and corn yield has large spatial variability. In specific, temperature tends to have negative marginal effects on corn yield in warmer regions, and positive effects in cooler regions. The spatial pattern of precipitation effects is more complicated since it is expected to be largely affected by local irrigation systems.

通过地理加权面板回归分析，我们证明了天气和玉米产量之间的空间变化关系。使用了2002-2006年期间美国958个玉米生产县的平衡面板数据。结果表明，气候变化与玉米产量的关系具有较大的空间变异性。具体来说，温度对较暖地区玉米产量的边际效应为负，而对较冷地区的边际效应为正。降水效应的空间格局比较复杂，因为预计主要受当地灌溉系统的影响。
