闻一多发起的新诗格律化运动，确立了新的艺术形式和美学原则，使新诗走上了规范化的道路，同时也使之接上了中国古典诗歌优秀传统的源流。闻一多所提出的“理性节制感情”的美学原则与新诗形式格律化的主张，既是新诗规范化的步骤，又是新诗民族化的途径，两者是合而为一的。这是闻一多对新诗发展的独特贡献。 Wen Yiduo initiated the movement of new poetry and established a new art form and aesthetics principle, which enabled the new poem to be on the path of standardization while also connecting it with the origin of the excellent tradition of Chinese classical poetry. Wen Yiduo’s proposed aesthetic principle of “rational feelings of temperance” and the idea of ​​“stylized” the form of new poetry are not only the normalized steps of the new poetry but also the means of ethnicization of the new poetry, which are combined into one. This is Wen Yiduo’s unique contribution to the development of new poetry.
