五四时期,在李大钊、徐宝璜等人的努力下,中国的舆论研究实现了两个重要的现代转型,即政治舆论研究的马克思主义转型和舆论研究的专业化、学科化转型,这标志了中国现代舆论学的产生。这两个传统迄今仍然是中国舆论研究的两个最重要的学术传统。 During the May 4th Movement, with the efforts of Li Dazhao, Xu Baohuang and others, the study of public opinion in China has realized two important transformations in the modern era: the transformation of Marxism in the study of political opinions and the specialization and discipline transformation of the study of public opinion, marking China The Emergence of Modern Public Opinion. These two traditions are by far the two most important academic traditions in Chinese media research.
