Abstract：Consumer competency refers to the needed capabilities to consume effectively and rationally in a changing market. Consumer competency can be conceptualized either on the basis of consumption decision-making processes model or on the basis of knowledge-attitude-skill model. The two models are different but related with each other. Nowadays, more and more researchers and enterprises focusing on investigating the concept, construct, education of consumer competency, as well as the decision-making models of consumers with lower levels of competency. In contrast, domestic research on consumer competency is relatively lacking and only a few studies investigated the financial literacy and consumer rights. Future study may focus on the localization of research of consumer competency, consumer competency in new forms of economy such as platform economy and share economy, and the education of consumer competency.
