Research on the Mechanism and Conditions of the System Stability of the Banking under the Competition Effect Jin-feng She1, Mei-xia Li2 1,2 School of Business of East China University of Science and Technology, Shanghai, China (jfshe@ecust.edu.cn, limeixia1102@163.com) Abstract - Along with the economic globalization and financial liberalization, bank competition has impacted on the banking stability profoundly. But the effect of bank competition on individual bank stability and the whole banking system stability is different. Based on the related articles at home and abroad and the analysis of the competition and stability of the banking in China, this paper thought that it is uncertain whether bank competition is good for the development of the bank individual stability. However it is beneficial to the system stability of the banking. This paper analyzed the mechanism of the stability of the system and conditions under the effect of banking competition by use of the system self-organization theory and the survival of the fittest theory. Keywords - Bank competition, stability of the banking system, stability mechanism, stability conditions I. INTRODUCTION Financial is the core of the modern economy, bank was regarded as the principal part of finical activities. Its steady development has great impact on harmonious and sustainable development of social economic system. With the economic globalization and financial liberalization, the banks face more and more competition, which produces far-reaching effect on banking stability. What kind of impact does competition in the banking sector have on banking stability? And how it affects banking stability? These issues become the hotspot of theoretical research and practical research at home and abroad in recent years, but the conclusions are not consistent. This paper attempts to summarize the situations of competitive effects on the stability of the banking system by studying the related literature and analyzing the competition and stability of the banking industry in China. Furthermore, the system self-organization theory and the survival of the fittest theory are used to analyze the mechanism and conditions of the banking system stability under the effect of banking competition. II. LITERATURE REVIEWS There are two different views about the effect of bank competition on bank stability. Some early scholars held the view that the banking competition was not benefit to the stability of the banking industry. Such as, Kelley (1990), Alien and Gale (2000a) considered that fiercer competition among banks would erode the incumbent monopoly rent and reduce the franchise value. As banks franchise values erode, this may create incentives to gamble and may lead to a shift towards riskier activities [1][2]. Shaffer, Sherrill (1998) found a phenomenon in the United States that the borrower's overall quality was declining in the financial market with the increasing number of the banks. The reason is that, when there is fiercer competition among banks, it would affect selecting criterion to bank lenders. If the applicants are refused by one or more banks, they can continue to apply for other banks. If the competition between banks is intense, and there is no cost or low cost for the lender loan application frequently, the low quality enterprises to obtain loans will be improved [3]. Hellman, Murdoek Stiglitz(2000) found that financial liberalization in United States and Japan reduced the enter doorsill for banking industry, relaxed the control of interest rate, and increased market competition of deposit through the establishment of deposit dynamic competition models. Therefore, banks tried to expand sources of funding by raising deposit rates. Raising the deposit interest rate means an increase in the cost of funds. It would erode the banks' profits, reduce the franchise value, and encourage banks to take more risk [4] . Cordella and Yeyati (2002) studied the bank competition effect on supervisory, they considered that banking competition reduced the investment for bank supervise [5]. In the further proof, Repullo(2003) thought the key factor, which make the competition encourage banks to take excessive risk, is that the risk revenue was mainly to bank shareholders, while the bear of loss was mainly shouldered by government or depositors[6]. However there are more and more researchers get the conclusion that banking competition is conducive to the stability of the banking through empirical research in recent years. In this view, they thought that a high concentration banks would get political asylum, accept the high lending rates from customers, and lead to more adverse selection and moral hazard. Such as, Boyd(2006) considered that the probability of bank failure was positively correlated with the degree of concentration, the loan-to-assets ratio had a significant negative correlation with the degree of concentration, and there was a significant positive correlation between bank profits and the degree of concentration and a tradeoff correlation between bank competition and financial stability[7]. Schaeck(2009) concluded that the highly competitive banking system was not prone to banking crises by studying on the relationship between bank competition and financial stability form the 38 countries from 1980 to 2003, including Japan, China, the United States, Germany, and so on[8]. Guo Jun (2003) analyzed the relationship between banking competition and stability from the functional point, and concluded that the instability of the banking system was caused by the bank's functional conflict, while the competition within the banking can effectively cut the bank's functions conflict, improve the matching function and effectively enhance the stability of banking system. Zou Peng-fei (2011), by studying the impact of bank competition on bank stability from an empirical point of view, obtained the results that as the credit market competition degree rise, the bank's bad loan rate reduced ceaselessly, the capital adequacy improved continuously, and the overall stability enhanced constantly[9]. There are two reasons why the impact of competition on bank stability has different conclusions in the existing literature. First of all, the different literature has different research object, some literature is based on the bank individuals, and the others is based on the whole banking industry. Second, the financial environment of different research object is not the same, different countries in different period has different financial environment, in which impact of bank competition on stability is different. Therefore, it is difficult to obtain a unified conclusion. III.

China had formed competition situation of state-owned commercial banks, joint-stock banks, city commercial banks and other banks co-exist, and market concentration is reduced year by year (showed in Table I). However, the data in the table shows that total assets of four major state-owned commercial banks is still dominant, China's banking industry is still in the stage of monopolistic competition and has not yet reached the moderate competition. Along with financial market competition degree in the banking industry increasing in China, how does the banking stability change? We try to analyze it by the means of correlation analysis between banking competition and stability. Generally, we use industry concentration ratio index (CRn) and HerfindahlHirschman Index (HHI) to reflect the competition degree. From reflection of table II, these two indexes gradually decreased since 2001, witch indicates that the competition of China commercial banks enhances gradually. The share of four major stateowned commerc ial banks in total assets ( %) Industry concentration ratio index ( CRn ), n = 4 HerfindahlHirschman Index ( HHI ) 2001 0.771 - 2002 0.750 - 2003 0.549 0.390 2004 0.536 0.381 2005 0.524 0.372 2006 0.513 0.364 2007 0.492 0.336 2008 0.467 0.322 To keep the stability of the banking, we can select the index of bank non-performing loan rate to represent the banking stability. The rate of non-performing loan is an important indicator to reflect the banking soundness, which can reflect the stability of the banking sector in a certain extent. The smaller the index value is, the better the stability of the banking is. This paper analyzed the correlation between the concentration ratio index of banking industry and bank non-performing loan rate form 2001 to 2008 , the correlation coefficient between them is 0.9114 (Table III), which shows that there is a strong positive correlation between degree of banking competition and stability. This analysis also shows that, when not reach the moderate competition, banking stability will increase along with the degree of the industry competition enhanced.

From the existing literature and the situation of banking competition and stability in China, the effect of competition on individual bank stability and banking system stability is different. On the terms of the individual bank, competition may improve its stability, or reduce it, or even collapse. But as a whole of the banking industry, the competition orderly will enhance the system stability of the banking under financial resource constraints, and whether the competition is insufficient or excessive will bring adverse effect. IV. SYSTEM STABILITY MECHANISM OF BANKING UNDER THE COMPETITION Financial resources are a kind of scarce social resources, which determined the fierce market competition among the commercial bank subsystems and internal banks. This competition promotes system stability of the banking mainly from two aspects. On one hand, the banking system is a selforganizing system with dissipative structure. From the perspective of self organization system evolution, the competition between banks not only makes banking system far from equilibrium state, but also promotes the system to the ordered structure evolution. Under the condition of market economy, banks face a different environment and resource condition. The responses of banks to market competition are also different. So the competition forms a kind of environmental forces which make all banks away from the equilibrium, into a dynamic non- equilibrium [11]. Specifically, competition can promote banks to carry out a variety ways of financial innovation, which not only makes the bank have the enough development at multiple levels, but also make the bank management efficiency, improve economic efficiency and promote their competition ability. At the same time, competition leads to the emergence of new ideas, new strategy and new combination in bank system, which promotes the bank's overall efficiency. In addition, competition can makes bank effort degree information open to the public, which could achieve more effective supervision and incentive to bank operator. Because of the competition makes banks facing the decisions between life and death, the bank must constantly improve its management mechanism and operational efficiency to survive. On the other hand, the main feature of the competition is the survival of the fittest. When facing on the external environment and condition, the different type banks in banking system have different adaptation and response, and the acquisition of material, energy and information quality are also different. All these cause the competition and survival of the fittest. Survival of the fittest mechanism of commercial banks have screening function, which can retain good banks of high efficiency and eliminate the poor efficiency banks, so as to enhance the overall quality and stability of the commercial banking system[10]. Survival of the fittest mechanism of competition is achieved by price mechanism. Competition promotes price changes in financial market, which have different effects on different banks. Under the environment of market competition, the bank whose marginal cost is higher than the market price will incur losses. And if the bank’s loss endangers bank capital, it will withdraw from the market. In contrast, the bank whose marginal cost is less than the market price will continue to live. In Figure 1, S0 stands for the initial market equilibrium, P0 and Q0 stand for the corresponding prices and the number of banking institutions respectively. With the development of economy, the financial service demand is increased. Assuming that the demand increase Q1, the prices will rise to P1 if the bank quantity is same. On the one hand, the prices increases profit space of the bank, which makes bank supply quantity increase and bank competition increase. And on the other hand, it can inhibit the demand for financial services, and decline the demand. Falling demand and survival of the fittest mechanism of competition make the equilibrium point at S2. And as this process continues, the banking system will get to automatic balance. V. CONDITION OF THE BANKING SYSTEM STABILITY UNDER THE COMPETITION To achieve dynamic system stability by self organization, bank must meet the following conditions: All bank institutions should adjust their behavior independently according to the changes in the financial environment, the diversity of bank institutions which can realize full competition and the smooth entry and exit channel of banks for the survival of the fittest. (1) Independence of bank institutions An independent bank institution has four basic characteristics.It provides financial products and services as the main source of its income, and its goal is to maximize the benefits. It must have the property right, by which it has the ability to take full responsibility and cost. It has the independent decision-making right. Otherwise, it would produce asymmetry of duty and right. ④ it has enough awareness of risk. Pric e The market supply1 The market supply2 S1 P 1 P 0 S2 S 0 A C 1 A C 1 innovation of financial instruments and financial transactions of property rights (such as merger, reorganization, transfer). Bank exit refers to the alteration or loss of the financial institution legal person status by the way of merger, division, dissolution, closure, and bankruptcy [12]. Banking entry and exit largely determined the competition degree in banking sector and its quantity. New life is the condition of ecosystem sustainability. Similarly, the bank entry is also the conditions of sustainable banking-system and only with effective access can make good financial institutions to achieve objectives of expanding the market and develop new markets or new areas of business. At the same time, bank entry is condition of competition too. No free entry, no full competition, and no full competition, no effective financial function. All that lives must die, which is the requirement of ecological balance, and it is also requirements of maintain financial stability. For those failing bank institutions, they would eventually threaten the interests of the public and depositors, so they should withdraw from the market. The International Monetary Fund's research also showed that it was vital to run banks exit on the stability of the banking system and competition. Fig 1 the dynamic stabilization process of banking system under competition VI. CONCLUSION (2) The diversity of bank institutions Similar to the stability of the ecological system, the system stability of the banking also relies on the diversity of bank institutions and the complexity of financial food-chain relations. Banking diversity mainly embodies the following like the diversity of financial institutions, the diversity of financial property right, the structural diversity, financial organization diversity, species diversity, and financial business and service diversity. In the long-term evolution process, different bank institutions are different in the organization structure and organization function, which forms the food chain of financial organizations by complement each other and mutually dependent relationship. The more complex the food chain relation is, the more abundant nonlinear interaction in system is and the easier to restore stability under internal and external interference. Conversely, if banking institutions are the same in the strategy, business, structure, and asset concentration, the relationship within banking system is very simple, and the system will hide the certain systemic risk. When it receives interference factors, it is difficult for banking system to restore stability by the fluctuation among various components of the system. (3) The smooth entry and exit channel of bank institutions In order to make the competitive mechanism of survival of the fittest smoothly in the banking system, it needs to have appropriate entry and exit channel for banks. Entry means that the banking institutions added branches, opening new financial business, the Competition is an inevitable product of the market economy. Competition among banks is the driving force for the banking development and the necessary condition to achieve the system stability in the increasingly globalized financial environment. In the competition, banking system realizes the dynamic balance and stability of the system through its selforganization and mechanism of survival of the fittest. But, to achieve dynamic system stability by self organization, bank must meet the following conditions: All bank institutions can adjust their behavior independently according to changes in the financial environment, the diversity of bank institutions which can realize full competition and the smooth entry and exit channel of banks for the survival of the fittest. Therefore, in order to promote the stable development of the banking sector, it is important to reform the financial system and create a financial environment and conditions of orderly competition.
