商业银行数字化转型与系统脆弱性

Digital Transformation of Commercial Banks and Systemic Vulnerability

随着数字金融的飞速发展,数字化转型已成为商业银行的一项战略要务.本文使用更加全面的中国银行业微观数据,以银行数字化转型的不同阶段所具备的风险收益特征为切入点,深入剖析其对系统脆弱性风险的动态影响机制.实证结果表明,银行数字化转型水平与自身的系统脆弱性风险呈显著的倒U型关系且结果十分稳健,在考虑内生性问题后依然成立.机制检验发现,银行数字化转型通过改变银行收入获取效率与主动风险承担来间接影响银行自身的系统脆弱性风险.本文的实证发现对于防范银行业系统性金融风险,理解数字化创新与风险管理的平衡,具有重要现实意义.

With the rapid development of digital finance,digital transformation has become a strategic imperative for commercial banks.This paper employs a more comprehensive data set from China Banking Database(CBD),and examines the relationship between bank digital transformation and systemic vulnerability risks.Empirical results indicate that there is a significant inverted U-shaped relationship between the level of bank digital transformation and its own systemic vulnerability risks,and the results are robust,remaining valid even after addressing endogeneity issues.Mechanism analyses reveal that bank digital transformation indirectly affects its own systemic vulnerability risks by altering income acquisition efficiency and active risk-taking.The empirical findings of this paper have important practical implications for preventing systemic financial risks in the banking industry and understanding the balance between digital innovation and risk management.
