摘　　要：传统金融学理论是对理想市场状况的完美抽象与诠释,而行为金融学刻画的则是现实交易的市场特征与结果,是对传统金融学研究范式过于严苛的理论假设进行放松的结果。传统金融学与行为金融学的分歧并不意味着两者之间存在本质上的矛盾,其实两者是同一理论体系的两个方面,应该相互补充和完善,而不是相互排斥。两者的相互补充与融合将成为现代金融学理论未来研究的主流方向,并将共同构成现代金融学理论的完整研究范式。Theory of traditional finance is a perfect abstrartion and interpretation of the ideal market,while behavioral finance mainly covers the characteristics and results of real business in the market and is a shifting-away from the too strict theoretical hypothesis of traditional financial research model.The disparity between traditional and behavioral finance doesn't mean that they are contradictory to each other in nature.These two are actually two aspects of the same theory and thus they should be complementary instead of excluding to each other.The complementation and integration of them will be the mainstream of the research on modern financial theories and helps to construct a complete research model of modern financial theories.
