| The financial crisis swiped the global, and it is exposed that a series of majordefects in the current bank regulatory capital international rules,which led to theprovision of the regulatory capital that can not fully absorb the losses during thecrisis.Therefor,in2010December, Basel Committee issued the " Basel iii ",which wasformally approved d in Seoul in2011at the G20.In this regard, China BankingRegulatory Commission issued a more strict Chinese version of " Basel iii "--"commercial bank capital management approach (Trial)".The new regulations putforward higher requirements on the capital structure of the commercial banks, andhave begun to implement in January1,2013.The implementation of the newregulations and adjustment and reorganization of financial supervision rules not onlyaffect the development strategy of bank, but also affect the capital structure of banks,operation mode and operation performance.This paper studies the influence of capital structure on business performance andseeks the method to optimize capital structure and improve business performance.The first and second part is theoretical analysis. Based on the research results ofdomestic and foreign scholars, the paper mainly analyzes related theories of bank’scapital structure and business performance, especially from the aspects ofshareholder structure, debt structure and the proportion relationship between the two,which provides theoretical support for the following research.In the third part, it analyzes the present situation of the capital structure of listedbanks in China mainly from the aspects of debt asset ratio,shareholder structure anddebt structure, then it analyzes Chinese listed banks’ business performance from theprofitability and asset quality, which establish the factual basis for the later empiricalanalysis.The fourth part is the empirical analysis. Through the empirical analysis, theconclusion are as followed: Chinese listed banks’ business performance is negativelycorrelated with the proportion of the first shareholder and debt asset ratio; Chineselisted banks’ business performance is positively correlated with the sum of proportionof top five shareholders, the largest shareholder of state-owned property andsubsidiary capital to core capital ratio.The fifth part is the conclusion and suggestions. On the basis of the empiricalanalysis, combined with the actual situation of Chinese banks, the following recommendations are made for the optimization of capital structure of listed banks:first, it is better to optimize stock right structure of listed Banks by reducing theshareholding ratio of the first major shareholder, keeping the equity ratio of the topfive shareholders at a high level, and maintaining the state control of the banks.Second, it is essential to optimize debt structure of listed banks, the methods of whichare to increase the proportion of subsidiary capital in the total capital, at the same timeto diversify the subsidiary capital structure and expand the subsidiary capitalfinancing channels. Finally, the optimization and improvement of externalenvironment are important, which needs to establish a perfect legal system andstrengthen supervision. |
