英文文献摘要：
This paper analyzes the effect that the imminent reform of the EU sugar beet regime will have on United Kingdom (UK) sugar beet farms. Specifically, we estimate a multi-product cost function to analyze the effect the changes on the sugar beet price support and quota will have on the crop allocation of sugar beet farms and their aggregate use of inputs. Based on these estimates we discuss the implications that changes in the crop patterns may have on farm environmental variables such as soil loss and groundwater pollution.

本文分析了即将到来的欧盟甜菜制度改革对英国甜菜农场的影响。具体地说，我们估计了一个多产品成本函数，以分析甜菜价格支持和配额的变化对甜菜农场的作物分配及其总投入使用的影响。基于这些估计，我们讨论了作物模式的变化可能对土壤流失和地下水污染等农业环境变量的影响。
