Abstract: Service robot is considered to be an important way to reduce costs, improve efficiency and promote service innovation. But how to use service robot to improve customer satisfaction, is a core concern of service enterprises. Drawing upon customer value hierarchy theory, this study constructs an impact model of service robots perceived intelligence and perceived cuteness on customer satisfaction, including the boundary condition of consumption motivation and the underlying mechanism of interactive experience. An exploratory study of 2,201 network texts of customers and two empirical studies of 622 adult respondents showed that perceived intelligence and perceived cuteness of service robot positively affect customer satisfaction and downstream behavior (patronage intention and willingness to share). Consumption motivation has a moderating effect on the influence of perceived intelligence and perceived cuteness of service robot. For utilitarian motivation, perceived intelligence has a greater impact on customer satisfaction than hedonic motivation. While for hedonic motivation, perceived cuteness has a greater impact on customer satisfaction than utilitarian motivation. And such moderating effect is mediating by customer engagement. This study not only makes theoretical contribution on clarifying the different effects of perceived intelligence and perceived cuteness of service robots on customer satisfaction, but also provides an important reference for service enterprises to introduce and apply service robots in practice.

Key words: service robot, consumption motivation；perceived intelligence, perceived cuteness, customer satisfaction
