【英文摘要】 Modern Chinese opera became an important form of literature and art as the result of innovation of traditional Chinese opera leaded by Chinese communist from Yan’an period to Cultural Revolution period. Yongko drama and model drama, the two styles of modern Chinese opera made particular status in the development of Chinese opera, even in the history of Chinese social political culture in the 20th century. Modern Chinese opera’s becoming mature and important, was not the necessary result of the inner evolution of Chinese opera, nor the incidental ending of picturing the image of state culture by Chinese government, but involved a series of questions about Chinese opera,modern state and the relationship between them. With the theme of“Chinese opera and state myth”, the dissertation focuses its attention on the complicated nexus of modern Chinese opera and the building of modern state. Such questions are included: what did modern Chinese opera do? Why it was Chinese opera and modern life material that established state myth? How did modern Chinese opera establish state myth? How were Chinese opera and modern life changed by the state when it established its myth? How did the folk from which Chinese opera came into being and grew up accept modern Chinese opera? How did modern Chinese opera influence the ideology of the folk and its daily life? Trying to answer all these questions will bring the study of modern Chinese opera into a great space and enter the common argumentation about the Chinese modern social politics and thinking culture, while exceeding the former study limited to the analysis on the inner of modern Chinese opera or incidental to the superficial discussion of social history, thus make the specialized study contact with the public field of thinking culture.The first two chapters of this dissertation give a definition of modern Chinese opera, and argue generally the tradition and foundation of modern Chinese opera as state myth. Then see about the character of modern Chinese opera, which is said representing modern life. The ideology of modern Chinese opera will be found, that is writing memory of revolution and utopia image of economy and society. So it is clear that in the script and stage of modern Chinese opera, there were little reality.The last three chapters combine history and logic.
