申梦晗副教授于公共管理学国际权威期刊Journal of Policy Analysis and Management发表论文

太阳集团tyc8722申梦晗副教授与我们的两位研究生汤志伟、梁晓霞，以及美国布朗大学博士后叶晓阳合作的论文“Migrant children’ s take-up of social health insurance: Experimental evidence from China”，近日于公共管理学国际权威期刊Journal of Policy Analysis and Management发表。

在“全民医保”的制度背景下，大部分城市开始落实流动人口凭居住证参保的政策。但是，虽然部分大型城市降低参保门槛，流动儿童在常住地参保率仍然不高。本论文通过随机对照实验的研究方法，通过为流动儿童家庭提供信息干预提高参保率。研究者设计了一个两阶段的3x2的随机对照实验：（1）将父母随机分配到对照组或两个处理组之一，其中一组接收关于符合参保条件或符合参保条件加上比较性收益和成本的信息；（2）通过短信提醒的方式，随机提醒部分家长参保截止日期。结果表明，仅告知符合参保条件并没有对参保产生促进作用。然而，提供符合条件加上比较收益和成本的信息显著地提高了社会医疗保险参保率。在干预的第二年，我们利用处理组的分配作为参保的工具变量考察参保的作用，研究发现参保并没有对儿童的健康产生显著的促进影响。

ABSTRACT

There is mounting evidence on the importance of health insurance for children’s health and well-being. However, many disadvantaged families do not enroll their eligible children in social health insurance programs. This study examines the effectiveness of interventions aimed at increasing social health insurance enrollment for disadvantaged migrant children in Guangzhou, China. We conducted a two stage randomized controlled trial with a 3 × 2 design: (1) randomly assigning parents to a control group or one of two treatment groups, where they received digital information on eligibility or eligibility plus comparative benefits and costs; and (2) nudging half of the parents with text message reminders about the enrollment deadline. Informing parents about eligibility alone did not have any impact. However, providing information on eligibility plus comparative benefits and costs increased enrollment in social health insurance in Guangzhou by over 44% (9.4 percentage points). Nudging produced no significant impact. Exploiting treatment group assignment as an instrument for coverage, we were unable to detect any positive effects of having social health insurance in the first year after the intervention.
