文章导读

       据统计,全球每年生产的可食用食物中,有三分之一是被浪费掉的。为解决日益增长的供需矛盾问题,实现资源的可持续发展,减少食物浪费变得越来越重要。社会影响理论认为,作为“社会人”,人们或多或少会受到其他人行为和态度的影响。社交媒体是一种重要的交流、信息传播的工具,个体每天在社交媒体上投入的时间量较大,那么是否可以通过它来干预食物浪费行为?它是否比其他信息传播工具更能有效地干预人们的行为和生活方式呢?本研究通过现场实验的方法,探讨了社交媒体、电子/纸质杂志和电子通讯几种不同形式的信息载体,分别对人们浪费食物行为的干预效果,并分析了这些干预方式间的差异性,以期找到减少食物浪费的有效途径。

摘要

       研究基于现场实验的方法,对大型零售商干预数百万消费者行为变化的情况进行评估和测量,是一项具有里程碑意义的研究。以前的研究表明,通过社交媒体互动可以影响个体的行为。在本文的实验研究中,实施了三种不同方式的干预信息来鼓励人们减少食物浪费。首先是社交媒体干预,利用零售商的Facebook主页与客户进行互动;再者是通过零售商的纸质/电子杂志和电子通讯这两种额外的信息进行比较干预。对照组为没有接触到任何干预信息的消费者。研究分别在干预信息实施后的一个月前、两个星期和五个月后,开展了三项对消费者食物浪费的自陈式调查。有趣的发现是,社交媒体、电子通讯干预以及控制组都显示消费者的食物浪费量及浪费次数显著减少,也就是说社交媒体并没有表现出更好的干预效果。所以本研究认为,社交媒体不具有以前研究中所显示的“面对面”互动的效果。这表明了,基于实验室的研究结果,可能过度地强调了社交媒体用来干预个体行为的作用。

文章亮点

• 社交媒体能够显著地干预食物浪费行为。

• 电子通讯能够显著地干预食品浪费行为。

• 零售商杂志在干预消费者食物浪费行为方面并不显著。

• 对照组个体食物浪费行为发生了显著的变化。

• 社交媒体在干预食物浪费行为上不具有“面对面”互动的效果

Abstract:

This paper reports on a landmark study to field-test the influence of a large retailer to change the behaviour of its millions of customers. Previous studies have suggested that social media interaction can influence behaviour. This study implemented three interventions with messages to encourage reductions in food waste. The first was a social influence intervention that used the retailer’s Facebook pages to encourage its customers to interact. Two additional information interventions were used as a comparison through the retailer’s print/digital magazine and e-newsletter. Three national surveys tracked customers’ self-reported food waste one month before as well as two weeks after and five months after the interventions. The control group included those who said they had not seen any of the interventions. The results were surprising and significant in that the social media and e-newsletter interventions as well as the control group all showed significant reductions in self-reported food waste by customers over the study period. Hence in this field study, social media does not seem to replicate enough of the effect of ‘face-to-face’ interaction shown in previous studies to change behaviour above other factors in the shopping setting. This may indicate that results from laboratory-based studies may over-emphasise the effect of social media interventions.
