On the willingness to pay for food sustainability labelling: A meta‐analysis
通过元分析系统梳理环境与社会标签信息对消费者食品支付意愿的影响，发现溢价因信息内容而异，社会议题关注度较低，为政策制定提供参考。
Abstract Sustainability labelling is an extremely complex, multifaceted, and debated topic. Through a systematic and meta‐analytical approach, we disentangled the informative contents of environmental and social labels and investigated their effect on the consumer willingness to pay for food products. The premium prices for sustainability labels are largely heterogeneous depending on the information disclosed. Generic and specific messages seem not to differ in terms of consumer acceptance. Not all facets are equally important as social issues tend to be less considered. Policy interventions should combine hard and soft measures to holistically achieve sustainability in the food system.
