目的: 分析基本医疗保险门诊保障水平对居民参保意愿、参保连续性和参保缴费档次的影响。方法: 基于CHARLS 2011-2018年四期调查数据,使用门诊报销比例衡量门诊保障水平,采用Probit模型探究门诊保障水平对居民参保行为的影响。结果: 基本医疗保险门诊保障水平提高能显著提升居民参保率,并且能够降低参保中断现象,提高参保缴费档次,提升居民参保质量。同时,门诊保障水平提高能够降低居民医疗保险参保的逆向选择行为,年轻人群和健康状况较好人群中门诊报销比例对参保率的影响更显著。结论: 基本医疗保险门诊保障水平能够提升居民参保意愿和参保质量,建议继续稳步提高基本医疗保险门诊保障水平,适时调整门诊报销起付线,提高门诊医疗费用报销比例,扩大报销范围。建立居民基本医疗保险缴费标准与经济社会发展水平及居民人均可支配收入的联动机制,制定更精细化和差异化的缴费政策。
