本文通过在中国上海进行的一个假设性选择实验，考察了中国能效标识是否会影响消费者对空调和冰箱的选择。一个潜在的类的方法，观察受访者和产品品牌之间的异质性。研究结果表明，上海消费者对中国能效标识的认知程度较高，并倾向于关注贴有能效标识的产品。此外，贴上一个假设的标签，表明与标准型号相比节省电费的空调和冰箱受到了显着的偏好，这表明制造商提供的信息越多，他们的产品就越受消费者的青睐。最后，按类别概率加权，购买更节能冰箱的意愿高于购买更节能空调的意愿，这意味着上海消费者有更大的动机为他们使用频率更高的电器支付更多的价格。
In this paper we conducted a hypothetical choice experiment in Shanghai, China, to examine whether the China Energy Efficiency Label influences consumers' choices of air conditioners and refrigerators. A latent class approach was applied to observe both heterogeneities among the respondents and product brands. Our results suggested that consumers in Shanghai were well aware of the China Energy Efficiency Label and tended to pay more attention to products with such labels. In addition, air conditioners and refrigerators affixed with a hypothetical label that indicates saving in electricity bills compared with a standard model received significant preferences, which suggested that the more information manufacturers provide, the more their products would be preferred by consumers. Finally, weighted by class probability, the willingness to pay values for more energy efficient refrigerators were higher than those for more energy efficient air conditioners, implying that Shanghai consumers have greater incentive to pay more for appliances they use more frequently.
