欧盟国内外银行盈利能力影响因素分析文献综述初稿.docx

1、欧盟国内外银行盈利能力影响因素分析通过1995 - 2001年期间国内和外国银行在15个欧盟国家的商业运营情况来了解银行的具体特点和整体银行业环境对影响盈利能力。结果表明, 国内和外国银行的盈利能力不仅受银行具体特点的影响，也受金融市场结构和宏观经济条件的影响。除了在集中情况下国内银行利润, 所有的变量都是有重大意义的，尽管它们的影响和关系对国内和国外银行并不总是相同。一、介绍 在过去的几年许多的因素造成了欧盟银行业竞争日益激烈。最重要的因素之一是针对服务、建立、运行和监督信贷机构的第二个欧洲指令出台，在银行和金融领域放松管制。这个指令为所有欧洲银行机构在单一欧洲金融市场和提供了平等的竞争条件

2、，因此银行正在先前无法预料的国内外竞争之中。另外, 最近一些的技术进步对规模经济和范围提供了更多的机会，而采用欧元也加速了行业的变化。此外,宏观经济政策后大多数国家通货膨胀率和利率逐步降低。最后,在越来越多的欧洲国家非金融公司被允许提供传统的银行服务,并且在竞争中进一步提高，银行被迫产生新的产品和寻找新客户。许多银行为了参加欧洲市场和银行业扩大被迫增加规模，通过合并和收购的方式进行了前所未有的整合。在环境快速变化的情况下，这些变化给在欧盟的银行带来很大的挑战，因此影响了他们的效能。格林指出，充足的收益是必要的条件让银行保持偿付能力,在一个合适的环境生存、发展和繁荣。考虑到银行业的健康发展和经济

3、知识增长，影响银行的盈利能力的潜在因素不仅和管理者有关，而且和众多利益相关者如中央银行,银行家协会、政府以及其他金融当局有关。二、文献综述参考文献与本文可分为三大类。第一部分是研究集中于银行的盈利能力的决定因素。第二部分包括研究欧洲银行的利润和成本效率。第三由研究比较国内外银行。在下面几个部分中,我们讨论这些类别中的每一个。三、决定因素和变量选择3.1 因变量本研究使用平均资产回报率(ROAA)来评估银行的性能。ROAA是把净利润表示为一个百分比的平均总资产。它显示了每欧元资产获得的利润并指明如何有效的银行的资产去设法创造收益。平均资产是用来在会计年度中发现发现资产上的任何差异。Golin(2

4、001)指出,平均资产回报率是衡量盈利能力的关键。32 决定因素和独立变量四个银行特征用作内部决定因素。这些都是银行的总资产、成本收入比、权益与资产比率和银行的贷款的比率除以客户和短期融资。此外,六个外部因素是用来检查环境的影响对银行的表现。四、数据和方法我们的示例是一个平衡面板数据集，由在15个欧盟国家的584家商业银行从1995 - 2001年期间的4088组数据组合而成。表2和表3分别展示了目前银行的数量所属的国家和所有权和样本特征。五、实证结果表4报告对银行的平均资本回报率（ROAA）的实证估计。第一列体现了把所有的银行(584)同时考虑的结果。第二、三列体现了我们通过银行经营这所属的

5、国家把银行分离出来的结果。我们定义一个银行是国外还是国内是依靠外国人的股份资本是否超过50%，这个子样本包括332家国内银行和218家外资银行。在这个阶段，约34个银行被排除在分析,由于我们没有足够的信息来辨别其是国内还是国外。除了在集中情况下国内银行平均资本回报率，所有的变量都是显著的,尽管它们对国内外银行的平均资本回报率的影响和关系并不总是相同的。这个模型的解释力对国内银行是更高的(调整R2国内银行等于0.6371，而外资银行等于0.3903),而f统计所有模型的重要性在1%的水平。这意味着额外的因素可能会影响外国银行的盈利能力。像威廉姆斯(2003)正确地指出,外资银行运行在一个受两个因

6、素影响的主机市场，分别是他们是属于外国跨国银行和他们的参与银行系统的主机。由比较高的显着系数的股权资产（EQAS）和成本收入比（COST）显示，在一般情况下，平均资产回报率的主要决定因素是资本实力及费用管理效率。股权资产与平均资本成本是正相关关系，无论我们考察国内银行还是国外的银行，而且它是国内银行盈利能力是最重要的决定因素。这一调查结果与以往的调查研究是一致的，资本充足的银行在破产和规模缩减方面面临着较低的成本，因此，它们的融资成本比较低或具有较低的外部资金的需求，促成了较高的盈利能力。成本收入比（COST）被预期是外资银行盈利能力的最重要的决定因素，是正如预期的那样的，呈现出负相关关系，这

7、些费用的增加会在很大程度上减少在欧盟银行的经营利润。很多学者也发现了费用管理不善是盈利能力差的主要因素。因此，在欧盟的商业银行应采取必要的行动，以实现更有效的成本控制，以进一步增加他们的利润。外国（-0.309）和国内银行（-0.144）之间的系数的差异可能是由于不当的管理操作以及与监测机构存在的距离。关于流动性，结果是喜忧参半。客户的净贷款及短期资金比率（LOFUND）在统计上显着，并与国内银行的盈利能力呈正相关，表明银行流动性资产持有量水平和盈利能力水平呈负相关关系，与预料的一样。对于外资银行来说，变量也很显着，但有一个负号，说明流动性和银行利润的正相关关系，出乎我们的意料，虽然与伯克（1

8、989）和Kosmidou（2006）的研究一致。无论是国内或国外银行，规模（SIZE）之间的关系和银行的业绩是负的。负系数表明，在这两种银行中，大银行的收入水平就会低于的利润，研究也发现要么经济规模和范围为较小的银行或金融机构的规模不够大。范德Vennet（1998）发现的证据表明，在欧盟规模经济效益只有在根据资产小于10亿欧元的最小银行才有效，此后报酬不变和规模不经济的最大银行超过1000欧亿。 六、结语在最近几年中，许多因素加剧了欧盟银行业的竞争，尤其是银行的操作环境的急速变化给银行带来了巨大的挑战。这是合理的假设去认为所有这些变化都必然会对银行的表现有一定的影响。格林在2001年指出，

9、银行需要足够的资金以维持偿债能力并在合适的环境中生存。银行的效率和经济增长之间的关系是有据可查的。与此同时，银行的破产会对经济产生不利的后果。因此，认识影响银行的盈利能力的潜在因素是必不可少的，不仅是为了银行经理，也是为了在15个欧盟国家众多的利益相关者，如的中央银行，银行协会，政府和其他金融机构。从这项研究中得出的结论对于那些经济和银行系统正经历根本性变化的新欧盟国家都是很有意义的。原文：Factors influencing the profitability of domestic and foreign commercial banks in the European UnionAbs

10、tractUsing bank level data this paper examines how banks specific characteristics and the overall banking environment affect the profitability of commercial domestic and foreign banks operating in the 15 EU countries over the period 19952001. The results indicate that profitability of both domestic

11、and foreign banks is affected not only by banks specific characteristics but also by financial market structure and macroeconomic conditions. All the variables, with the exception of concentration in the case of domestic banks profits, are significant although their impact and relation with profits

12、is not always the same for domestic and foreign banks.Keywords Banks; European Union; Profitability1. IntroductionOver the last years a number of factors have contributed to the growing competition in the European Union (EU) banking sector. One of the most important factors is deregulation, promoted

13、 by the Second European Directive on Banking and Financial services, concerning establishment, operation and supervision of credit institutions. This Directive sets out the principles of banking in the Single European financial market and provides equal competitive conditions for all European bankin

14、g institutions. As a result banks now compete in previously inaccessible domestic and foreign markets. Furthermore, a number of recent technological advances offered more opportunities for economies of scale and scope while the adoption of euro accelerated the changes in the industry. For instance,

15、income generation from foreign exchange transactions has been lost while the pricing of banking products and services has become more transparent, enhancing competition. Furthermore, the macroeconomic policies that were followed in most countries gradually reduced inflation and interest rates. Final

16、ly, in more and more European countries non-financial firms were allowed to offer traditional banking services, leading to further increase in competition. Therefore, banks were forced to generate new products and seek new customers. This is reflected in the continued diversification across geograph

17、ical areas and business lines. Many banks have been forced to increase in size in order to compete in the enlarged European market and the banking industry experienced an unprecedented level of consolidation through mergers and acquisitions.It is reasonable to assume that all these changes posed gre

18、at challenges to banks in the EU as the environment in which they operated changed rapidly, a fact that consequently had an impact on their performance. As Golin (2001) points out adequate earnings are required in order for banks to maintain solvency, to survive, grow and prosper in a suitable envir

19、onment. Given the relation between the well-being of the banking sector and the growth of the economy (Rajan and Zingales, 1998, Levine, 1997 and Levine, 1998), knowledge of the underlying factors that influence banks profitability is essential not only for the managers of the banks but for numerous

20、 stakeholders such as the Central Banks, Bankers Associations, Governments, and other Financial Authorities. Knowledge of these factors would also be of particular interest to the new EU countries whose economies and banking systems are experiencing fundamental changes during this period.The aim of

21、this paper is to extent earlier work on the determinants of profitability of banks in the EU and examine to what extent the performance of commercial banks operating in EU markets is influenced by internal factors (i.e. banks specific characteristics) and to what extent by external factors (i.e. mac

22、roeconomic and financial market structure) in view of the ongoing process of integration and concentration. Although a growing literature uses efficient frontier approaches to examine the profit and cost efficiency of EU banks (e.g., Altunbas et al., 2001 and Schure et al., 2004), to our best knowle

23、dge, there are only few studies that focus on the determinants of profitability while focusing on the EU as a total1 (e.g., Molyneux and Thorton, 1992 and Staikouras and Wood, 2003).Molyneux and Thorton (1992) were the first that examined the determinants of banks profitability operating in 18 Europ

24、ean countries over the period 19861989. Most recently the European banking sector was examined by Staikouras and Wood (2003) that considered banks from 13 EU countries over the period 19941998. The present study attempts to provide additional and more recent evidence on the determinants of banks pro

25、fitability in the EU. In order to accomplish this task, our paper differs from the earlier mentioned studies in several aspects. First of all, we include more recent years in the analysis by examining the period 19952001. Furthermore, we examine more factors by introducing the influence of additiona

26、l financial market structure variables such as stock market capitalization to GDP, stock market capitalization to assets of deposits money banks and assets of deposits money banks to GDP, not considered in the above studies. Finally, we are the first that distinguish between foreign and domestic ban

27、ks. During the last years both developed and developing countries around the world have relaxed restrictions on foreign banking and most of them now allow more foreign banks to undertake more banking-related activities in their domestic banking markets, mainly because of the increasingly importance

28、of international trade in goods and financial services. As Goddard et al. (2001) point out since 1989 the number of foreign banks has increased in every banking market in Europe, which now hold a large proportion of banking assets in the UK (53% of banking sector assets in 1999), Belgium (24% of ass

29、ets in 1999), Portugal (12% of assets in 1999) and France (12% in 1999). Previous studies that distinguish between domestic and foreign banks focus mostly on differences on profit and cost efficiencies using frontier approaches (e.g., Berger et al., 2000 and Sathye, 2001) or financial characteristic

30、s that differentiate these two groups of banks (e.g., Kosmidou et al., 2006a) and not on whether the internal and external determinants of profitability among domestic and foreign banks are different.The rest of the paper is structured as follows: Section 2 provides a literature review of related st

31、udies. Section 3 describes the dependent and independent variables while Section 4 presents the data and methodology used in the study. The empirical results are presented in Section 5. Finally, in Section 6, the concluding remarks are discussed.2. Literature reviewPrior literature related to the pr

32、esent paper can be classified in three broad categories. The first consists of studies that focus on the determinants of banks profitability. The second consists of studies that examine the profit and cost efficiency of European banks. The third consists of studies that compare domestic and foreign

33、banks. In the following sections we discuss each one of these categories.2.1. Studies on the determinants of profitabilityFollowing the early studies of Short (1979) and Bourke (1989) a number of more recent studies have attempted to identify some of the major determinants of banks profitability. Th

34、ey consider internal and external factors and examine a single country (e.g., Berger, 1995, Angbazo, 1997, Guru et al., 1999, Ben Naceur, 2003, Mamatzakis and Remoundos, 2003, Kosmidou et al., 2005 and Kosmidou, 2006) or a panel of countries (Molyneux and Thorton, 1992, Demirguc-Kunt and Huizinga, 1

35、999, Abreu and Mendes, 2001, Staikouras and Wood, 2003, Hassan and Bashir, 2003 and Goddard et al., 2004). In the discussion that follows we focus on the studies that examine the EU banking market.2The study of Molyneux and Thorton (1992) is one of the first that examines the determinants of banks p

36、rofitability in several countries. The results indicate a positive association between the return on equity and the level of interest rates, bank concentration and the government ownership. In a more recent study, Abreu and Mendes (2001) examine Portugal, Spain, France and Germany and find that loan

37、 to assets and equity to assets ratios have a positive impact on interest margins and profitability. They also find that operating costs have a positive impact on net interest margins measures but not on profits measures, while the opposite holds for banks market share. From the macroeconomic variab

38、les, inflation is relevant in all cases, while the nominal effective exchange rate does not have an impact on performance. The unemployment rate has a negative sign in all regressions and is significant in the case of profits although not on net interest margins measures. Staikouras and Wood (2003)

39、examine the performance of a sample of banks operating in thirteen EU banking markets. The results indicate that loans to assets ratio and the proportion of loan loss provisions are inversely related to banks return on assets, as well as that banks with greater levels of equity are relatively more p

40、rofitable. The funds gap ratio is also significant and positively related to performance. Furthermore, the authors found no evidence to support either the structureconductperformance or the efficient hypothesis. Two of the three macroeconomic indicators, the variability of interest rates and the gro

41、wth of GDP had a negative impact, while the level of interest rates had a positive effect. Goddard et al. (2004) investigate the determinants of profitability in Denmark, France, Germany, Italy, Spain and the UK, for the period 199298. They find only weak evidence for any consistent or systematic si

42、zeprofitability relationship and a positive relationship between capital-assets ratio and profitability. The relationship between the importance of off-balance-sheet business in a banks portfolio and profitability is positive for the UK, but either neutral or negative elsewhere.2.2. Studies on the p

43、rofit and cost efficiency of EU banksIn recent years, there has also been an increase of academic studies that focus on the efficiency of financial institutions using frontier analysis. Berger and Humphrey (1997) outline 130 studies, covering 21 countries, multiple time periods and various types of

44、institutions that applied three parametric (i.e. stochastic frontier approach (SFA), distribution free approach (DFA), thick frontier approach (TFA) and two non-parametric (i.e. data envelopment analysis (DEA), free disposal hull (FDH) frontier approaches for determining the best-practice frontier a

45、gainst which relative efficiencies are measured.3 The efficiency of a bank is measured relatively to that of the best-practice banks of similar size, with most studies focusing on cost efficiency rather than profit efficiency.4 Some recent studies also consider both cost and profit efficiency (e.g.,

46、 Berger and Humphrey, 1997 and Berger and Mester, 1997), as well as risk variables (e.g., Berger and DeYoung, 1997, Berg et al., 1992, McAllister and McManus, 1993, Mester, 1996 and Rao, 2005).Although the EU is considered relatively under researched (given its size and importance) there is now a gr

47、owing strand of literature that examines the efficiency of EU banking institutions. Examples of such studies are Altunbas et al. (2001), Bikker (2002), Maudos et al. (2002), Schure et al. (2004) and Staikouras et al. (2005). The studies of Dietsch and Weil (1998), Cavallo and Rossi (2002), Casu and

48、Molyneux (2003), are also interesting as they focus on most of the main EU banking sectors. Earlier studies, as the ones of Berg et al. (1993), Pastor et al. (1995), Lang and Welzel (1996), Lozano-Vivas (1997), Dietsch and Lozano-Vivas (2000), focus mostly on sub-sets of selected markets or individu

49、al countries such as the nordic countries, France, Germany and Spain among others.2.3. Studies on foreign versus domestic banksOther studies have employed similar techniques to compare the efficiency of foreign and domestic banks. Hasan and Hunter (1996), Mahajan et al. (1996), and Chang et al. (1998) conclude that foreign banks in the US are less cost efficient than domestic banks, while Seth (1992) and Nolle (1995), find that foreign-owned banks are not as profitable as domes
