Based on the SOR (Stimulus-Organism-Response) theoretical model, this study analyzes the influence mechanism of short video content characteristics on consumers’ purchase intention. By means of literature research and empirical analysis, it focuses on three dimensions: visual appeal, information practicality, and anchor credibility, and reveals their path of influence on purchase decisions through the mediating role of perceived value. The study adopts a questionnaire survey method to collect data from short video shopping users, and uses SPSS and AMOS software for statistical analysis. The results show that: visual appeal indirectly promotes purchase intention through perceived value; information practicality and anchor credibility have a significant impact on purchase decisions through the mediating role of perceived value; perceived value plays a partial mediating role between content characteristics and purchase intention. Based on these findings, to optimize the short video operation ecosystem, this study puts forward the following suggestions: merchants should build a “three-dimensional integrated” content matrix and optimize from three aspects: visual presentation, information screening, and anchor training; platforms need to establish a content quality evaluation system; regulatory authorities should improve the norms for short video advertisements.
