Retail sales are closely tracked by economists since spending by consumers drives the bulk of overall US economic activity.

自消费者支出推动美国大部分整体经济活动以来，经济学家就一直在密切注意零售额。

The notion of " retail therapy" , consumers driven to spend when they are feeling blue, is an obvious example of shopping's emotional side.

消费者在心情沮丧时的消费行为，即所谓的" 购物疗法" ，便是购物行为感性一面的明显例子。
