The Research On The Influence Of Capital Structure On Liquidity Risk Of Commercial Banks Of China

During 2007 financial crisis,financial institutions went bankrupt because of lack of liquidity and excessive leverage.With Basel III,the management of capital structure and liquidity risk has become an important content in the management of commercial bank,CBRC issued "Commercial Bank Capital Management Method" and"Commercial Bank Liquidity Risk Management Method(trial)" in 2012 and 2015.Capital structure and liquidity risk of our commercial banks had some changes,therefore,research on the influence mechanism of commercial banks' capital structure on liquidity risk and measuring the effect of bank capital structure on the liquidity risk are helpful to enrich the theoretical system of management of commercial banks,boost stable and healthy development of financial system and even the economy.Through combing domestic and foreign literature research,related theory that commercial bank capital structure affects liquidity risk has been concluded,the influence mechanism that capital structure has on liquidity risk of our country's commercial banks has been clarified,the current situation of capital structure and liquidity risk of our commercial banks has been described.And further,using 2007-2015 national commercial banks(large commercial banks and joint-stock commercial banks)and other commercial banks(urban commercial banks and rural commercial banks)as a sample for empirical research,the impact of national commercial banks and other commercial banks' capital structure on liquidity risk has been studied.The results showed that liquidity risk was affected by capital structure of commercial banks significantly,increasing tierl capital adequacy ratio will significantly decrease liquidity risk,but banks' liquidity risk will be increased largely when commercial banks increase subordinate-debt ratio.And increasing total capital adequacy ratio and tierl capital adequacy ratio can reduce liquidity risk largely for other commercial banks.Considering current situation,commercial banks should strengthen the supervision of bank capital adequacy to prevent liquidity risk,joint-stock commercial banks can moderately increase tier 1 capital adequacy ratio,joint-stock commercial banks and urban commercial banks control subordinate-debt ratio to prevent bank liquidity risk,CBRC should supervise capital adequacy ratio of commercial banks,CBRC and CSRC should improve market mechanism of banks'capital supplementary.
