绿色消费虽然受到越来越多的关注,但消费者的绿色承诺却很难转化为实际的购买行为,出现了消费者的不作为现象。本研究从解释水平理论视角出发通过探讨时间参照对绿色消费的影响,揭示了绿色消费不作为发生的心理机制及其边界。研究发现,消费者在近期情境下对绿色产品的购买意愿低于远期,即个体更倾向于在将来而不是现在购买绿色产品,出现了绿色消费的不作为现象。尤为重要的是,环保意识对消费者不作为的弱化作用受制于个体的产品环境怀疑:产品坏境怀疑较低时环保意识的弱化作用明显,而产品环境怀疑较高时环保意识的弱化作用则不存在。

伦理消费(Ethical consumption,EC)是指消费者在获取、使用或处置产品时考虑到个人消费行为对社会、环境或动物福祉的影响。虽然伦理消费日渐流行,但在金钱支付时伦理消费的态度却往往难以转化为实际的行为,即言行不一。本文从解释水平理论视角出发,以"心理距离→解释水平→个体反应"为分析框架展开。从时间维度上来说,在态度评价阶段和产品选择阶段两个时间点上,消费者与伦理产品的心理距离远近不同,分别激活了高低解释水平表征;高低解释水平下个体在动机和认知上又存在诸多差异,这种差异导致两个阶段的反应不同,继而出现伦理消费者态度与行为的分离。未来研究应重点关注如何根据解释水平理论有效提高伦理消费行为。
