Abstract

This study examines optimal location of cattle feeding among Alberta and the north-western U.S. states. Optimal location is based on comparative advantage (reflected in lower cost) in the production of resources such as feeds and feeders, and final product of boxed beef. Transportation costs of resources and final product also influence optimal location. A spatial equilibrium model is developed to determine optimal location amoung seven regions. It is a linear programming cost minimization model that applies to 1988. A production function for transforming intermediate resources into final product (boxed beef) is used and regional demand for boxed beef is specified. Alberta beef supply and disposition for 1988 is simulated, and various policy alternatives are then applied to this base model. Results indicate Alberta can be competitive with U.S. regions in feeding and processing cattle. Comparison of actual 1988 cattle feeding patterns to "optimal" feeding patterns indicated by the model leads to several inferences. Significant impacts on numbers of cattle fed in Alberta arise from removal of (or alterations to) the current method of paying the Crow Benefit. The Alberta cattle sector shows considerable sensitivity to this polocy through its impact on barley price. Study models indicate that Alberta cattle feeding and processing industry would expand with Crow rate removal. Had Pacific Rim demand for high quality beef been greater, both northern and southern Alberta would have increased exports by shipping beef through Vancouver. Exports to the Pacific Rim would have displaced beef shipments from Alberta to eastern Canada. Depreciation of the value of the Canadian dollar would also have led to increased activity in the Alberta cattle sector. Alberta imported more feeders from the U.S. as value added cattle feeding and processing activities increased in Alberta. The additional boxed beed was shipped south to the U.S.
最优区位研究:艾伯塔省养牛业与美国地区的竞争力
本研究考察了阿尔伯塔省和美国西北部各州养牛的最佳位置。最佳位置是基于饲料和饲料等资源生产的比较优势(反映在较低的成本上),以及盒装牛肉的最终产品。资源和最终产品的运输成本也影响最优选址。建立了一个空间平衡模型,以确定七个区域之间的最佳位置。这是一个适用于1988年的线性规划成本最小化模型。使用了将中间资源转化为最终产品(盒装牛肉)的生产函数,并指定了盒装牛肉的区域需求。模拟了1988年艾伯塔省牛肉的供应和处置情况,然后将各种政策选择应用于该基本模型。结果表明,阿尔伯塔省在饲养和加工牛方面可以与美国地区竞争。将1988年实际的牛喂养模式与模型显示的“最佳”喂养模式进行比较,可以得出几个推论。由于取消(或改变)目前支付乌鸦福利的方法,对阿尔伯塔省饲养的牛的数量产生了重大影响。阿尔伯塔省的养牛部门通过对大麦价格的影响对这一政策表现出相当大的敏感性。研究模型表明,阿尔伯塔省的牛饲养和加工业将随着克劳率的降低而扩大。如果环太平洋地区对高质量牛肉的需求更大,阿尔伯塔北部和南部都将通过温哥华运输牛肉来增加出口。对环太平洋地区的出口将取代从阿尔伯塔到加拿大东部的牛肉运输。加拿大元的贬值也会导致阿尔伯塔养牛业的活动增加。随着增值牛饲养和加工活动在阿尔伯塔省的增加,阿尔伯塔省从美国进口了更多的饲料机。这批装箱的蜜蜂被运往南方的美国
