Under a retail context, Donovan and Rossiter (1982) applied S-O-R model to study the impact of emotion on customers’ presence behaviors. They considered: (1) In general conditions, appropriate arousal level can promote customer to accepting behaviors, but either excessively high or excessively low arousal level will make customers take avoidance behaviors; (2) In pleasant environment, arousal level and customers’ accepting extent have posi-tive correlation; (3) In unpleasant environment, arousal level and avoidance behavior have positive correlation. Wakefield and Blodgett (2002) discovered that customer’s good emotional status had positive correlation with the duration of their stay, the quantity of their shopping commodity and the amount of their consumption. The dominance of environment can significantly affect customers’ buying behaviors, which will not only impact the theories of retail enterprises, but also correlate closely with customer loyalty. Therefore, making use of physical environment to regulate customers’ positive emotions and initiate their accepting behaviors becomes the issue concerned intensely by retail enterprises. Baker et al. (1986, 1992) studied the connection between physical environment and customer psychological status. Baker et al. (1992) considered that an individual’s emotional response to environment revealed the ability the environment regulated emotions, that is, the extent that customer perceives pleasure and arousal in the environment. They examined the impacts of two kinds of environmental factors on customers’ emotional assessments and found that surrounding environment factors (replaced by background music) affected the extent of customer pleasure along with social factors (replaced by store service staff); while the extent of arousal that social factors influenced customers complied with the opinions of S-O-R model in their findings, that is, customer emotions on store environment had important moderate effect on buying behaviors.
