有限理性行动者的偏好变化与行为策略：一个初步的理论模型
Preference changing and behavioral strategy of actors with bounded rationality: a preliminary theoretical model

依托有限理性的理论思路与概念工具，本文挑战了传统经济行为分析中的偏好稳定与效用最大化假定，构建了一组包含四种行动者类型的理论模型。以此为基础，本文进一步描述了连续行动过程中的偏好变化与策略选择，修正并丰富了以“显示性偏好”理论为代表的既有研究对偏好与行为之间复杂关系的理解。与行为经济学侧重短期情境性分析不同，本研究关注偏好与行为的演化（进行或退行）机制，以及在特定条件下行为显示或隐藏偏好的可能。这项工作不仅有助于重新审视关于偏好变化的既有结论，也能为新的行为实验提供设计思路。
：Based on the theoretical approach and concept tools of bounded rationality, through the hypothesis of stable preference and utility maximization, a theoretical model including a group of four categories of actors has been proposed in this study. On this basis, preference changing and strategy selection in the process of sequential action has been further described to revise and enrich the understanding on the complicated relationship between preference and behaviors in current studies, as represented by the Revealed Preference Theory. Different from behavioral economics which puts particular emphasis on short-term situational analysis, this study shows more concern about the evolution (progressive or regressive) mechanism, and the possibility of revealing or hiding preference in behaviors under specific conditions. This study may help reexamine existing conclusions on preference changing, but also provide design ideas for new behavior tests
