[目的/意义]文章旨在阐明行为经济学理论在信息行为研究中的应用和贡献，以推动其在信息行为研究 中的进一步发展。［方法/过程］以国内外期刊和学术会议中发表的应用行为经济学理论的信息行为文献为研究对 象，通过归纳和总结的方法，梳理了行为经济学理论在这些文献中的应用情况及理论贡献，并对未来的研究进行 展望。［结果/结论］第一，目前行为经济学理论已被广泛地应用在信息检索和信息评估等研究主题。第二，行为经 济学理论从理解用户信息行为中的有限理性和“非理性”行为、理解用户行为决策的损益规则、揭示认知和行为策 略中的直觉推断法则、解读信息行为中的认知偏差四个方面，为揭示用户信息行为背后的认知方式和思维逻辑提 供理论基础。最后，从信息行为跨学科理论发展、时代前沿的信息行为研究以及用户信息决策科学化三个方面提 出相应的展望。

[Purpose/significance] The purpose of this study is to elucidate the applications and contributions of behav⁃ ioural economics theories in information behaviour research, thereby fostering the continued development of these theo⁃ ries within the realm of information behaviour research. [Method/process] Drawing upon the extensive research litera⁃ ture on information behaviour, encompassing both domestic and foreign journals and academic conferences, this study offers a comprehensive generalization and summary of the utilization of behavioural economics theories in the realm of research. Furthermore, it highlights the theoretical contributions of these applications and provides a forward-looking perspective on future research avenues. [Result/conclusion] First, behavioural economics theories have been widely applied to information retrieval, information evaluation and other research themes. Second, behavioural economics theo⁃ ries provide a theoretical foundation for revealing the cognitive styles and thinking logic behind users’information be⁃ haviours from four aspects: understanding bounded rationality and‘irrational’in users’information behaviour, under⁃ standing the rules of gain and loss in users’decisions, revealing the heuristics in cognitive and behavioural strategies, and interpreting the cognitive biases in information behaviours. Finally, the corresponding outlooks are proposed from three aspects: interdisciplinary theory development in information behaviour, the zeitgeist information behaviour re⁃ search, and scientific decision-making of users.
