Pigs in Space: Modeling the Spatial Structure of Hog Production in Traditional and Nontraditional Production Regions
构建了一个县级生猪生产空间模型，分析集聚效应、城市扩张、投入品可得性等因素如何影响美国15个主要生猪生产州的布局与强度，对农业政策制定者和区域经济研究者有参考价值。
Abstract We posit a spatially explicit, county‐level model of the hog production sector and estimate how numerous firm‐specific, locality‐specific, and spatial agglomeration factors affect the location, movement, and intensity of hog production within 15 key hog production states. Spatial agglomeration, urban encroachment, input availability, firm productivity, local economy, slaughter access, and regulatory stringency variables affect the sample regions' spatial organization. Analyses suggest that western states in the sample may shape hog production levels by wielding traditional business recruitment and retention tools (e.g., tax rates, environmental stringency) while Corn Belt states may shape hog production via nontraditional tools (e.g., land use controls).
