【摘要】：企业的资本结构与经营绩效的关系一直是学术界探讨的热点。商业银行因有着其特殊的资本结构以及在经济社会中重要的地位,其资本结构与经营绩效的相关性更值得进行研究。针对商业银行的特殊性,本文从两个方面考虑商业银行的经营绩效,即盈利能力与风险状况(资产质量)。盈利能力选用净利润指标,风险状况选用不良贷款率指标。普通企业的资本结构一般指企业的权益资本与债务资本的比例。对于商业银行资本结构的划分,采用了巴塞尔协议的视角,即核心资本与附属资本,并且附属资本规模不得超过核心资本的100%。同时,商业银行的核心资本结构又包含了一般工商企业的股权结构。本文采用2005年——2010年14家上市商业银行的面板数据对商业银行资本结构与经营绩效的关系进行分析。通过EVIEWS计量软件对数据进行了处理,在模型的选择上通过F检验和Hausman检验,在随机效应模型、固定效应模型、混合效应模型中选用了固定效应模型。分别用商业银行的净利润和不良贷款率对其资本结构各变量进行回归分析。基于实证研究的结果,本文针对优化资本结构以及提高绩效给出了如下几点建议：增加和优化商业银行附属资本、优化核心资本、加快商业银行的创新进程、建立健全制度环境。由于商业银行的数据本身难以获取,加上我国主要上市银行上市时间较短且上市银行数量较少,导致所选取面板数据的样本量偏少。另外,商业银行核心资本和附属资本中的具体结构数据难以找齐全,因此未能做到详细的结构分析。在以后的研究中,希望能够使数据更为全面有效。
[Abstract]:The relationship between capital structure and operating performance has been a hot topic in academic circles. Commercial banks have their special capital structure and important position in economic society. The correlation between capital structure and operating performance is worth studying.
In view of the particularity of commercial banks, this paper considers the operational performance of commercial banks from two aspects, namely profitability and risk (asset quality). The profitability index is net profit index, and the risk condition index is non-performing loan rate index. The division of bank capital structure adopts the perspective of Basel Accord, that is, core capital and subsidiary capital, and the scale of subsidiary capital should not exceed 100% of core capital.
This paper uses panel data of 14 listed commercial banks from 2005 to 2010 to analyze the relationship between capital structure and operating performance of commercial banks. The data is processed by EVIEWS software. The model is selected by F test and Hausman test. The random effect model, fixed effect model and mixed effect model are selected. Based on the results of empirical research, this paper gives the following suggestions for optimizing capital structure and improving performance: increasing and optimizing subsidiary capital of commercial banks, optimizing core capital and accelerating commerce The bank's innovation process and the establishment of a sound institutional environment.
Because the data of commercial banks are difficult to obtain, and the time of listing of major listed banks is short and the number of listed banks is small, the sample size of panel data is relatively small. In future research, we hope to make the data more comprehensive and effective.
