Institutional reform of marketing and related services to agriculture, with particular reference to Africa
回顾了1980年前农业营销和投入品供应系统的官方垄断历史，分析了改革动力、引入竞争和个体积极性的可行路径，以及政治、种族和利益集团等障碍，对关注非洲农业发展的学者和政策制定者有参考价值。
Over the decades to 1980 agricultural marketing and input supply systems came increasingly under official monopolies. Dissatisfaction with the incentives offerred to producers and with the costs to governments has sparked interest in reform. Practicable ways of introducing more competition and mobilizing potential individual initiatives are presented. Obstacles to progress in this direction include political commitments of governments, ethnic concerns and patronage interests. External aid can help ease these constraints.
