【摘要】：近年来，随着金融自由化、一体化的深入，金融业务创新层出不穷，金融并购此起彼伏。在全球金融多元化的浪潮中，我国商业银行越来越重视多元化经营和发展，本文从理论和实证两个方面对多元化经营影响银行绩效的效应进行分析。具体来讲，在理论分析部分，首先以企业多元化经营的相关理论为基础从正反两方面分析了多元化经营对银行绩效的影响效应，其次结合我国商业银行多元化发展现状对多元化的实际效果进行初步分析，并指出目前我国商业银行多元化过程中所存在的问题。在实证部分，本文引入赫芬达尔指数(Herfindahl Index,HI)衡量银行的多元化程度，通过建立多元化绩效模型，运用2000-2012年间我国15家主要商业银行的面板数据，对商业银行多元化与银行绩效的关系进行了系统的分析。并在此基础上根据资产组合理论对银行风险进一步分解，试图更深一步探讨多元化与银行风险间的关系。在理论分析和实证研究的基础上，本文得到的主要结论有：近十年来，，多元化经营对我国商业银行的盈利能力产生了积极影响，多元化不仅提高了商业银行的资产利润率，而且也提高了其权益收益率；多元化经营在提升商业银行盈利能力的同时有助于降低商业银行的经营风险，随着多元化程度的提高，我国商业银行资产利润率和权益收益率的波动都在减小；非利息收入通过多元化收益抵消了其波动带来的不利影响，实现了风险分散作用，有利于降低银行收入的波动性。综合而言，多元化经营对我国商业银行的综合绩效产生正面影响。最后，根据本文的结论，从政府监管和银行自身两个层面提出了多元化经营的发展建议，以期对提高商业银行多元化的经营效益提供借鉴和参考。
[Abstract]:In recent years, with the deepening of financial liberalization and integration, financial business innovation emerges one after another, financial mergers and acquisitions one after another. In the tide of global financial diversification, China's commercial banks pay more and more attention to diversification and development. This paper analyzes the effects of diversification on bank performance from both theoretical and empirical aspects. Specifically, in the part of theoretical analysis, first of all, based on the related theories of enterprise diversification, this paper analyzes the effect of diversification on bank performance from both positive and negative aspects. Secondly, this paper analyzes the actual effect of diversification according to the present situation of diversification of commercial banks in China, and points out the problems existing in the process of diversification of commercial banks in China at present. In the empirical part, this paper introduces the Huffindar Index (Herfindahl Index,HI) to measure the degree of diversification of banks, through the establishment of diversification performance model, the panel data of 15 major commercial banks in China in 2000-2012 are used. This paper makes a systematic analysis of the relationship between the diversification of commercial banks and the performance of banks. On this basis, according to the portfolio theory to further decompose the bank risk, try to further explore the relationship between diversification and bank risk. On the basis of theoretical analysis and empirical research, the main conclusions of this paper are as follows: in the past ten years, diversification has had a positive impact on the profitability of commercial banks in China, and diversification has not only improved the profit margin of commercial banks, but also increased the profit margin of commercial banks. At the same time, it also improves the rate of return on equity; Diversification not only improves the profitability of commercial banks, but also helps to reduce the risk of commercial banks. With the increase of diversification, the volatility of profit margin and return on equity of commercial banks in China is decreasing. Non-interest income offsets the adverse effects of its volatility through diversification of income, and realizes the risk dispersion, which helps to reduce the volatility of bank income. Overall, diversification has a positive impact on the comprehensive performance of commercial banks in China. Finally, according to the conclusion of this paper, from the two aspects of government supervision and bank itself, this paper puts forward some suggestions for the development of diversified management, in order to provide reference for improving the diversification of commercial banks.
