撒哈拉以南非洲地区金融稳定的影响因素研究

发布时间：2022-12-07 06:21

　　本研究旨在探讨2000-2017年期间撒哈拉以南非洲地区金融稳定的潜在影响因素。为了实现这一研究目标,本文根据数据的可用性,使用了 38个国家的不平衡面板数据。为了解决银行业可能出现的内生性问题,本文采用广义矩估计方法对所提出的假设进行了实证检验。因为SSA的经济体基本上都是银行,而且大多数没有资本市场,因此本文分析的重点是金融系统的银行业。本研究主要以银行Z评分、银行监管资本及不良贷款占贷款总额比率作为衡量金融稳定的主要指标。根据现有文献,可能影响金融体系稳定的自变量分别为银行效率、银行竞争、银行集中度、金融服务准入、金融深化和公共部门治理。回归分析是以金融自由度、最近全球金融危机和宏观经济商业周期为控制变量进行的。研究的主要结果表明,银行的盈利能力与整体金融稳定性密切相关,并降低了投资组合风险。研究还发现,成本管理的低效性导致了银行稳定,并降低了银行的风险承担水平。根据这一观察结果,监管机构可以采取禁止性措施,如强制银行持有更多股本以抑制风险承担,从而保持稳定。尽管银行参与非传统活动似乎增加了资本持有量,但这导致了高风险承担和整体稳定性下降。实证分析结果进一步表明,最大的三家银行的...
