摘要
信息不对称问题在健康卫生领域普遍存在。在农村学生眼镜使用方面,信息不对称的一种表现形式是学生有"戴眼镜会伤害视力"的错误认知。基于对西北农村地区2 248名初中生的调研数据,研究发现,近四成学生有"戴眼镜会伤害视力"这种错误认知。这种错误认知显著阻碍了学生对眼镜的使用,使学生的戴镜率和配镜率都显著降低。农村学生眼镜市场"市场失灵"的10%可由"戴眼镜会伤害视力"这种错误认知解释。
Information asymmetry is a key problem existing in health care market.One kind of information asymmetry about spectacles for rural students is the misperception that spectacles will be harmful to vision.We conducted a survey sampling2248 students from western rural junior high school in 2013.Our analysis showed that about forty percent of students believed that spectacles were harmful to their vision.This misperception was quite a barrier to accessing spectacles.The students with this misperception had lower ownership and usage of spectacles than the students without.Ten percent of students＇ spectacles ＂market failure＂ are caused by this misperception that spectacles are harmful to vision.
