摘　　要：“经济理性”是经济学的传统研究假设,却因背离现实而受到质疑。基于行为人稀缺的心理资源和系统固有的不确定性而产生的“有限理性”正逐步取代“经济理性”成为经济学研究的理性假设。不同的理性观点可以从决策的视角得到系统地解释和比较。并且,随着理性假设的演变,经济行为的决策标准也相应从单一静态最优向多元动态平衡转变。＂Economic rationality＂ is a traditional research hypothesis of economics, but it is doubted because of its betrayal of reality. ＂Limited rationality＂ out of psychological resources and systematic born uncertainty based on the scarcity of behavioral man, is now gradually substituting＂economic rationality＂to become a rationality hypothesis of economic researches. Different views on rationality could be explained and compared from the angle of decision. Moreover, with the evolution of rationality hypothesis, the decision standard of economic behavior will finally move from still static state to dynamic balance.
