Abstract: Traditional stylistics mainly concentrates on vocabulary, sentence pattern and rhetoric to describe the style. In recent years, scholars began to attach more importance to the style in grammar research. However, most of the current studies tend to be microanalysis and have no macro-theoretical support, thus it’s hard for them to discover deeper problems of the style. According to the features of Chinese discourse and based on punctuation clause with definite boundaries, generalized topic theory proposes the concepts of general topic and topic structure. The thesis makes a comparative study on the stylistic differences of work reports and novels, involving topic of named entity, adverbial topic, predicate topic, logical topic and relational topic, etc. The thesis also makes a reasonable explanation for these differences. Although work reports and novels differ greatly in style, no one has ever made a comparative study from the perspective of topic-comment, and there is no extensive statistical analysis based on a corpus up to now. The work of this thesis enriches the theory of statistical stylistics, and lays a solid foundation for the application of computer auto-analysis of topic structure, auto-judgment of composition level, and textual classification by style, etc.
