疫苗是具有正外部性的有益物品,对于正外部性产品,竞争性市场往往会供给不足。离散选择实验近年来被广泛地应用到卫生经济领域,可以用来解决复杂的、多维度评价目标的选择行为研究。对离散选择实验在疫苗接种偏好和需求领域中应用的介绍,为国内相关研究提供借鉴。
Vaccines are positive items of positive externalities and are often under-supplied to competitive markets for positive externality products. In recent years, discrete choice experiment has been widely applied to the field of health economy, which can be used to solve the research on the selection behavior of complex and multidimensional evaluation objectives. The introduction of the application of discrete choice experiment in the field of vaccination preferences and needs provides reference for domestic related research.
