Non-equilibrium Analysis of Migrant Workers ' Medical Insurance System under the Background of Citizenization

The participation of migrant workers in medical insurance of urban workers is a formal institutional arrangement. However,in reality,the insurance participation rate of migrant workers is low and the medical insurance taken by the migrant workers is not sufficient,which seriously hinders the process of the citizenization of migrant workers. The main reason lies in the unbalanced supply and demand of the current system. With the continuous advancement of the citizenization process,the rural migrant workers' demand for medical insurance has changed.However,our research found that the supply of medical insurance system for migrant workers is seriously inadequate,the system and the institutional environment are disconnected,the internal contradictions of the system are increasing,and a large amount of potential profits are accumulated under the current system. Potential profit is the motive force to promote institutional innovation and promote the reform of current system to strike a balance.

海马脑片缺氧损伤电位机制的研究

本实验在海马脑片采用微电极记录技术，观察了缺氧损伤电位（ＨＩＰ）的电生理特性，并研究了其产生机制。实验结果表明：①ＨＩＰ是突触在缺氧过程中功能暂时恢复的反应；②随着缺氧程度的加重，ＨＩＰ出现时间前移，持续时间缩短；③ＨＩＰ的出现表明突触功能的丧失发生在突触膜损伤之前，其消失代表突触传递不可逆性损伤的发生，即突触膜损伤的开始；④大剂量腺苷不能阻止ＨＩＰ的产生，表明ＨＩＰ的出现不是由于腺苷浓度的降低。

城镇职工医疗保险基金运营“收不抵支”风险及应对策略——基于2010-2014年度统计数据的分析

城镇职工医疗保险基金是我国社会保障基金的重要组成部分,其运营发展关系国家经济建设、社会稳定和职工福利。本文基于2010-2014年度统计数据,利用实证模型对中国城镇职工医疗保险基金运转现状及可能隐含的问题进行了预测和评估,研究结果表明:从长期来看,城镇职工医疗保险的统筹基金将会出现较严重的“收不抵支”现象,虽然个人账户基金“赤字”并未显现;中国城镇职工医疗保险基金营运责任主体“缺位”和制度设计“泛行政化”、统筹层次过低、保值增值渠道单一、隐性缺口扩张等问题日益凸显,基金的可持续运营状况令人担忧。因此,为了实现城镇职工医疗保险基金的长期财务收支平衡和基金的可持续发展,本文分别从纵向分层一体化改革、分类监管和多渠道营运等方面提出了有针对性的政策建议。

参加城镇职工医疗保险对农民工劳动供给的影响研究

基于2017年中国流动人口动态监测数据和234个地级城市匹配数据,系统考察城镇职工医疗保险对农民工劳动供给的影响。研究表明:(1)参加城镇职工医疗保险会降低农民工的劳动供给时间并提高劳动效率,呈现出收入效应和积极的劳动供给效应。(2)职工医保存在较明显的劳动供给效应分化。对“单位+个人”参保的农民工主要呈现出收入效应,对灵活就业身份参保的农民工则产生缴费约束;职工医保对缓解老一代农民工过度劳动的效应更强。(3)机制分析发现,健康水平在职工医保影响农民工劳动供给中发挥了部分中介效应,消费水平在职工医保影响农民工劳动供给水平中发挥了遮掩效应。
