英文文献摘要：
Genetically modified (GM) cotton varieties have changed many aspects of cotton production in the United States. The advent of GM varieties has fueled the ongoing trend of increasing farm size and fewer farmers. Mississippi is no exception to this trend. The rapid adoption of GM cotton varieties in Mississippi has allowed some producers to increase the acreage of their farming operation. This study analyses the impact of GM varieties on relative profitability over certain types of land tenure arrangements. The type of land tenure arrangement and the cost associated with the arrangement are compared to determine relative probabilities of breaking even for different farm sizes in the Mississippi cotton industry.

转基因棉花品种改变了美国棉花生产的许多方面。转基因品种的出现加剧了农场规模扩大、农民减少的趋势。密西西比州也不例外。在密西西比州，转基因棉花品种的迅速采用使一些生产者得以增加他们的农业经营面积。本研究分析了转基因品种对某些类型土地所有权安排的相对盈利能力的影响。土地所有权安排的类型和与安排相关的成本被比较，以确定在密西西比棉花工业中不同农场规模盈亏平衡的相对概率。
