【摘要】：随着利率市场化进程的不断推进、金融脱媒脚步的加快、同业竞争的加剧,过去银行通过存贷款业务带来的息差就能持续盈利的状况已经不复存在。这样的背景下,近年来同业业务逐渐成为银行主要业务之一。同业业务的创新发展一方面为银行发展带来了活力,改善了银行的经营状况,为银行业转型升级提供了新方向。另一方面,资金在金融系统内的快速融通满足了不同的投融资需求,提高了资金利用效率。但是,与此同时银行在开展同业业务时存在许多潜在的风险因素,削弱了监管的效力,对金融系统的稳定产生不良影响。正确地认识同业业务,探究同业业务所带来的风险问题对于规范同业业务发展十分重要。因此本文将通过定性与定量的研究方法,阐述同业业务发展的现状、业务模式、发展的驱动因素。在此基础上,从微观和宏观两个层面探索同业业务可能带来的风险和金融系统不稳定的问题。通过对同业业务的梳理以及近年来出现的“钱荒”问题,本文认为同业业务容易引发商业银行流动性风险的问题。因此,本文余下的部分利用我国21家商业银行2009~2015年面板数据,结合PCA方法,综合考察商业银行流动性的影响因素,分析同业业务对银行流动性的影响。实证结果显示:样本中国有商业银行、股份制银行、城商行农商行三类银行中,国有商业银行整体流动性水平较高、中小规模城商行农商行流动性水平相对薄弱;同业资产业务与同业负债业务均与银行流动性水平呈负相关关系,同业业务的扩张会引起流动性水平的下降。
[Abstract]:With the development of interest rate marketization, the acceleration of financial disintermediation and the aggravation of interbank competition, the situation that banks can make profits continuously through deposit and loan business in the past no longer exists. In this context, interbank business has gradually become one of the main business of banks in recent years. On the one hand, the innovation and development of interbank business bring vitality to the development of banks, improve the operating conditions of banks, and provide a new direction for banking transformation and upgrading. On the other hand, the rapid financing of funds in the financial system meets different investment and financing needs and improves the efficiency of capital utilization. However, at the same time, there are many potential risk factors in the development of interbank business, which weakens the effectiveness of supervision and has a negative impact on the stability of the financial system. It is very important to understand the interbank business correctly and to explore the risks brought by the interbank business in order to standardize the development of the interbank business. Therefore, through qualitative and quantitative research methods, this paper expounds the status quo, business model and driving factors of the development of the same industry business. On this basis, the risks and financial system instability caused by interbank business are explored from both micro and macro levels. Through combing the interbank business and the problem of "money shortage" in recent years, this paper thinks that the interbank business can easily lead to the liquidity risk of commercial banks. Therefore, the remaining part of this paper makes use of the panel data of 21 commercial banks in China from 2009 to 2015, combined with the PCA method, to investigate comprehensively the influencing factors of the liquidity of commercial banks, and to analyze the influence of interbank business on bank liquidity. The empirical results show that among the three kinds of banks, state-owned commercial banks, joint-stock banks and agribusiness banks, the overall liquidity level of state-owned commercial banks is relatively high, while the level of liquidity of small and medium-sized commercial banks is relatively weak. Interbank assets business and interbank liability business have negative correlation with bank liquidity level, and the expansion of interbank business will lead to the decline of liquidity level.
