Despite China’s fast-growing e-commerce and its great achievement in promoting poverty alleviation through consumption, little is known about Chinese consumers’ online ethical consumption.  Using the payment card elicitation method, this paper designs a within-subject survey and a between-subject survey to investigate Chinese consumers’ quality perception and preference for apples from poverty-stricken areas.  The results show that before “information shock”, emphasizing that taste and safety attributes of apples from poverty-stricken areas are the same as the conventional ones, Chinese consumers on average are willing to pay a 31% premium for apples from poverty-stricken areas.  After “information shock”, both the within-subject and between-subject designs show a minimal drop of the premium, implying that the ethical attribute is the main motivation for buying apples from poverty-stricken areas.  The regression results show that quality perception of private attributes has significant effect on consumers’ willingness to pay (WTP) for apples from poverty-stricken areas, and trust in government supervision of e-commerce plays an essential role in motivating online ethical consumption.
