Consumer acceptance of food biotechnology based on policy context and upstream acceptance: evidence from an artefactual field experiment
通过在瑞典进行人工实地实验，研究了政策背景和上游参与者接受度如何影响消费者对具有健康和环境益处的转基因食品的接受度。
The European Commission recently proposed new rules allowing ‘opt-outs’ by member states from a Europe-wide approval system for genetically modified (GM) foods. An artefactual field experiment was performed in Sweden to test whether changing the policy context and acceptance by upstream actors influenced consumer acceptance of a GM product with direct tangible health benefits and indirect environmental benefits. The results indicated that acceptance was lower in more restrictive policy scenarios and higher in less restrictive contexts. Moreover, acceptance of upstream actors was policy context-dependent and differed between participants opposed to or accepting the technology.
