Based on the theory of logistics customer service demand and the basic theory of KANO model, this article takes SF Express as the research object. By collecting satisfaction survey questionnaires, a logistics service quality analysis of SF Express based on KANO model is established. The “Better Worse Index Analysis Method” is used to further evaluate the correlation between each element and customer satisfaction, and thus identify the problems and reasons for the current logistics service quality. Finally, corresponding solutions are proposed based on SF Express's current operating conditions.
