Abstract:With the continuous development of artificial intelligence technology, chatbots are gradually becoming an important tool for enterprises to improve customer experience. Based on self-determination theory, this study explores the impact and mechanism of functional and human-like features of chatbots on customers’ continuance intention. We collected 406 valid data through a questionnaire survey and conducted empirical analysis using PLS-SEM and Bootstrap methods. The results indicate that: (1) Social presence in human-like features has a significant positive impact on perceived information quality and perceived enjoyment in functional features, and the impact of social presence on continuance intention is more prominent. (2) Perceived information quality and perceived enjoyment can positively affect customers' continuance intention through the mediating effects of autonomy and relatedness, respectively; both autonomy and relatedness play a mediating role in the impact of social presence on continuance intention. (3) Social presence can have an indirect impact on customer's continuance intention through a chain mediation of perceived information quality - autonomy, as well as perceived enjoyment -relatedness. The research findings not only enrich the relevant research on customers' continuance intention to chatbots, but also provide theoretical guidance for enterprises on how to configure chatbots to meet customer psychological needs and improve their continuance intention.
