Abstract: In order to study the relationship between perceived servicescape and customer citizenship behavioral intention, the concept model among perceived serviceescape, customer emotion, perceived service quality and customer citizenship behavior in a restaurant was theoretically established based on the environmental psychology. The proposed concept model and hypotheses were tested by the structural equation, which made the following three conclusions. The first, the perceived servicescape will influence the customer citizenship behavioral intention through customer emotions. The second, customer positive emotion has a stronger influence on customer citizenship behavioral intention than that of the customer negative emotion. And the third, restaurant level has moderate effect between perceived servicescape and customer emotion. This study provids the theory basis for enterprises adjusting the servicescape to prompt the produce of customer citizenship behavior.
