摘　　要： 对人类行动的说明，合理性预设是必要的。但是对于行动说明中是否存在统一的合理性概念存在激烈争论。合理性假设的必要性体现在两点：首先，使研究者理解行动者的行动得以可能；其次，刻画行动者对目的和手段的思考和算计。决策论从形式上刻画了一个理性人对于目的和手段的慎思推算，但是，无论是经典决策论，还是前景理论或者可错可改模型都不能提供行动说明中统一的合理性理论，因为这些理论均无法有效给出关于效用和信念度的一致性系统。 The presupposition of rationality is necessary for the explanation of human action.An intense discussion,however,centres on the question of whether the unified concept of rationality exists in the explanation.There are two points that show why the supposition is necessary.One is that it makes the understanding of human action possible,and the other is that it characterises how actors consider their aims and means.Decision theory illustrates in form how a rational person deliberates upon his aim and means.However,neither classical decision theory nor prospect theory provides human action with the unified theory of rationality,since they are unable to offer a consistent system concerning efficiency and the degree of belief.
