选择实验近年来快速发展并被广泛应用于各个领域的价值评估。本文指出,在一系列陈述偏好方法中,选择实验具有两个核心优势:一是完备的经济理论基础和实证方法体系;二是与真实市场情景相吻合的高信息负荷。高信息负荷在为研究提供更多偏好信息的同时,也大幅提高了实验设计的难度,并在实验过程中引起了一系列偏差。本文从实验设计效率、现状偏差、实验设计维度、信息处理策略、排序效应和假想偏差六个方面介绍了目前学界对选择实验方法效度的研究进展。
Selection experiments have developed rapidly in recent years and are widely used in various fields of value assessment. This article points out that in a series of presentation preferences, the choice experiment has two core advantages: one is the complete economic theory foundation and the empirical method system; the other is the high information load that matches the real market situation. While high information load provides more preference information for research, the difficulty of experimental design is greatly improved and a series of deviations are caused during the experiment. In this paper, the current research progress on the validity of the selection experiment method is introduced from six aspects: experimental design efficiency, current status deviation, experimental design dimension, information processing strategy, sorting effect and hypothetical deviation.
