本文试图从中国文化特质角度探寻科诨形成的原因。高度发达的诗歌艺术的挤压使戏曲形成了诗歌化的欣赏趣味，趋向雅化，并使戏曲产生重大的缺失。悠远的俳优滑稽传统则被作为争取观众，抗拒诗歌挤压，抵制雅化的必然选择。二者同时遇合于相对固定的戏曲形式，于是，科诨的产生就势在必然。 This article attempts to explore the reasons for the formation of Khotan from the perspective of Chinese cultural traits. The squeeze of the highly developed poetic art has made opera play a poetic appreciation taste, tend to elegant, and make drama a major absence. The long-range traditions of fooling around are regarded as the inevitable choice for gaining audiences, resisting the pressure of poetry and resisting yahua. At the same time, the two converge on a relatively fixed form of opera, so the emergence of science is inevitable.
