选择空调商品时节能信息标注的效果——根据网络的随机比较实验的分析

The "Label Display Program for Retailers" under the revised Act on the Rational Use of Energy, which was introduced in 2006, obligates retailers to make efforts to display information on energy saving performance so that consumers can recognize and compare the performance of products. In this paper, we examine which types of energy saving information increase the probability of selecting energy-saving air conditioners by utilizing an online randomized controlled trial. Our empirical results indicate that the selection probability of energy-saving products increases when multistage ratings and expected annual electricity bill information are displayed. On the other hand, our results also reveal that information on achievement rate in terms of energy-saving standards does not significantly increase the selection probability of energy-saving products.
