摘要(Abstract):
文章基于不完全信息动态博弈模型,对信息披露、存款保险制度与系统性风险之间的作用机制进行了理论分析,并使用2006-2014年24个国家137家上市商业银行的面板数据进行了实证考察。研究发现,提高银行的信息披露程度,有助于降低融资成本和存款保险缴费费率,引导其减小银行间资产的相关性,从而降低系统性风险;存款保险的金融稳定效应不明显,提高信息披露程度有效缓解了存款保险制度的道德风险,两者在降低银行系统性风险方面存在协同效应。设计合理的存款保险制度、经验丰富的监管当局和严格的监管体系有助于发挥市场约束作用,限制存款保险的道德风险,从而维护金融体系的稳定。因此,在我国正式实施存款保险制度的背景下,监管部门应加强银行信息披露和优化存款保险设计,以更好地防范我国金融体系的系统性风险。
