研究蓝光（波长约460纳米）在实体环境和手机屏幕上如何影响消费者在移动购物中对享乐型与实用型产品的购买意愿，发现蓝光比传统白光更促使人想买享乐型产品。
ABSTRACT According to multidisciplinary research, the blue light has important consequences for human beings’ productivity and well‐being, as it positively influences their circadian, endocrine, and neurobehavioral functions. This paper examines how blue light—in both the physical environment and a mobile display—influences consumers’ purchase intentions in mobile shopping. Specifically, this paper proposes that consumers who are exposed to certain conditions of blue lighting (identified by an emission spectrum centered at 460 nm; i.e., “actinic blue”), in either a room environment or via a smartphone, are more inclined to purchase hedonic rather than utilitarian products. After describing the study, which compares the effects of blue lighting to more traditional white lighting (identified with an emission spectrum centered at 635 nm; i.e., “warm white”), the paper discusses results, alongside the implications for theory, marketing practice, and future research.
