监管约束下不良率与流动性风险研究

IBased on the unbalanced panel data of 177 banks from 2012 to 1019, this paper studies the non-performing loan ratio, deposit competition and liquidity risk of banks. This paper analyzes the differences between banks in the choice of non-performing assets disposal methods and deposit competition from the perspectives of the disposal methods of non-performing assets and the deposit competition, and concludes that the restriction of the disposal methods of non-performing assets is the reason why small and medium-sized banks do not show the liquidity trade-off in the short term. Through the analysis of the degree of deposit competition faced by big banks and small and medium-sized banks and the impact of deposit competition on the non-performing loan ratio, it is concluded that deposit competition will weaken the short-term trade-off effect of big banks. Based on the study of the communist party of China put forward two assumptions: Ⅰ due to the limitation of non-performing assets disposition, non-performing loan ratio affect the liquidity risk of large Banks and small and medium-sized Banks are different; Ⅱ deposit competition will weaken the effect of short-term trade-off of big Banks non-performing loan ratio effect on liquidity risk difference is narrowing. Through empirical test, this paper finds that in China\'s banking industry, whether large banks or small and medium-sized banks, in the long term supervision is effective. In the long run, the influence of non-performing loan ratio on liquidity risk is inverted U-shaped, while in the short run, the influence of current non-performing loan ratio on liquidity risk in large banks shows a trade-off effect, while in small and medium-sized banks, the influence of current non-performing loan ratio shows a spiral effect. The deposit competition will cause the increase of the non-performing loan ratio of banks, and the influence of the non-performing loan ratio on the liquidity risk of big banks in the short term will disappear due to the deposit competition. Finally, based on the empirical results, this paper puts forward relevant policy recommendations for Chinese regulators and financial institutions.
