Abstract

Abstract: Discrete choice experiment is an important method for estimating the demand or preference of non-market products in health economics. Developing attributes and attribute-levels is one essential determinant for the effectiveness of the experiment，but there is no unified process and method regarding how to conduct it. To provide a key methodological reference for future research，we detailed the development of attributes and attribute-levels for a discrete choice experiment for estimating demand of long-term care insurance via using multiple methods including theoretical analysis，literature review，policy text analysis，and expert interview，in which the pilot policies regarding long-term care insurance and their differences were outlined，with consideration for current and future development of these policies.

Key words: Discrete choice experiment, Attribute and attribute-level, Long-term care insurance

摘要： 离散选择实验是卫生经济领域测量非市场产品需求或偏好的重要方法之一，其特征及其水平设置环节是决定实验有效性的重要因素，但目前缺乏统一的设置流程与方法。本研究以长期护理保险需求为例，综合运用理论分析、文献综述、政策文本分析、专家访谈多种方法，以既能勾勒出政策轮廓又能刻画各试点差异为出发点，以考虑政策现状水平兼顾其未来发展为原则，对离散选择实验的特征及其水平设定过程进行详细描述，以期为后续相关研究提供的方法学参考。
