都市叙事提供了一个分析和理解沈从文及其创作的切入点。沈从文的都市叙事在一定程度上反映了作家所经历的跨文化交流中的“文化冲击”及其体验。这种“文化冲击”以城乡文化冲击和苗汉文化冲击的方式体现出来。城乡文化冲击使沈从文的都市叙事以都市批判的方式展开,苗汉文化冲击则使他选择了人性视角来进行他的都市批判。沈从文的都市和乡土,都只是一种想像的存在物。 Urban narrative provides a starting point for analyzing and understanding Shen Congwen and his writing. The urban narrative of Shen Congwen reflects to some extent the “cultural impact ” and his experience in the cross-cultural exchange that writers experience. This “Cultural Impact ” is reflected by the impact of urban and rural culture and the impact of Miao and Han culture. Urban and rural cultural impact makes Shen Congwen’s urban narrative unfold in the way of urban criticism, and the impact of Miao and Han culture makes him choose humanity perspective to conduct his urban criticism. Shen Congwen’s city and native land are only an imaginary being.
