Abstract

In designing extension systems, answers to the question ‘How many extension agents are needed?’ are always given. The question is, in practice, answered intuitively and this paper enquires whether economically optimal answers are conceivable. It appears that, so long as farmers vary in their propensity to innovate, there probably are least-cost solutions to the question in respect of specific projects. The underlying theory is complex and the treatment presented here is simplified, perhaps oversimplified. In discussion, the importance of diffusion processes as an agent of innovative change is emphasised.

作为热带农业推广系统组成部分的创新诱导扩散观察
在设计扩展系统时,回答“需要多少扩展代理?”’总是被给予的。在实践中,这个问题的答案是直观的,本文探讨的是经济上最优的答案是否可以想象。看来,只要农民的创新倾向不同,就有可能在具体项目中找到成本最低的解决方案。潜在的理论是复杂的,这里提出的处理是简化的,也许是过度简化的。在讨论中,强调了作为创新变革动因的扩散过程的重要性。
