“赋、比、兴”含义研究较多，成因研究罕见。今就其成因问题作了三点推论：一是巫史文化的产物，即原始宗教内容向艺术形式的积淀，以及实用记事的需要。二是礼乐文化的产物，即当时出于礼仪的思考，出于政治、外交、人际关系的需要。三是理性认识的产物，即当时的诗人们已认识到物象的表意功能远远大于抽象语言的表意功能。上述三解，也许按其序列有先后之分，也许三种成因共同作用，也许某种成因主之，其余辅之。 The meaning of “Fu, than, Xing” more research, genetic research rare. This article makes three inferences about its causes: First, the product of the witch history culture, that is, the original religious content to the accumulation of art forms, and the need for practical notes. The second is the product of ritual and cultural, that is, out of etiquette at that time, out of political, diplomatic and interpersonal needs. The third is the product of rational cognition, that is, the poets at that time realized that the ideographic function of objects is much larger than that of abstract language. The above three solutions, perhaps according to their sequence, may have three causes of interaction, perhaps some of the main reasons, the rest of the auxiliary.
