改进的效率测算模型、影子银行与中国商业银行效率

商业银行及其效率的高低是金融供给侧结构性改革的关键环节,而可以压缩的“坏”投入和影子银行对商业银行效率产生重要影响。本文首次建立理论模型并分析影子银行影响商业银行效率的路径;方法上,同时区分投入和产出的“好”或“坏”,拓展只区分产出的“好”或“坏”的效率测算模型;实证上,首次测算并分析“坏”投入、影子银行业务对商业银行利润、风险和效率的影响。结果表明:理论上,影子银行会同时增加风险承担和利润,但无法确定经风险调整后的利润增加能否提升效率;只区分产出的模型高估了效率,尤其是显著高估四大行和股份制商业银行第一阶段的效率,大型商业银行依靠网点的扩张不利于效率的提升;影子银行业务提升了四大国有银行尤其是股份制银行的效率,但对中小型商业银行效率影响较小。总的来看,压缩“坏”投入和规范影子银行是增加有效金融供给、优化金融供给结构和提升银行效率的重要途径。     

银行竞争提高了企业投资水平和资源配置效率吗？——基于分支机构空间分布的研究

银行贷款是我国企业融资的重要方式,在企业生产经营中发挥着举足轻重的作用。2006年和2009年,我国先后两次放松了商业银行分支机构市场准入规制,银行分支机构空间分布发生了较大变化,银行竞争水平和服务实体经济能力明显提升。本文利用2001-2012年国家统计局工业企业数据,以企业周边银行分支机构的数量衡量银行竞争水平,研究银行竞争对企业投资的影响。研究发现,银行分支机构数量的增加显著提高了企业投资水平和投资效率。进一步研究表明,银行分支机构数量增加对企业投资效率的提升作用主要表现在投资不足的企业和非国有企业中,企业融资约束降低和代理冲突减弱是银行竞争提高企业投资效率的主要原因。本研究拓展了银行竞争以及企业投资和资源配置效率的相关文献,对供给侧结构性改革和银行业高质量发展具有启示意义。     

竞争与效率——基于我国区域性商业银行的实证研究

针对文献中有关银行业竞争与效率之间关系的争论,本文采用我国区域性城市商业银行和农村商业银行的数据做了进一步的探索。文章采用随机前沿分析法计算银行效率水平,并利用银保监会发布的银行分支许可证信息构建区域竞争指数,从而考察区域银行业竞争程度对银行经营效率的影响。研究印证了竞争程度的增加可以提高区域性商业银行的效率,但竞争度对农村商业银行效率的影响更大。结果表明,我国区域性商业银行中的竞争与效率之间存在非线性关系,过度的竞争会对区域性商业银行的效率造成负面影响。通过对区域性银行跨区经营行为的进一步分析,发现竞争会影响区域性银行跨区经营决策,进而改变其经营效率。具体来讲,当区域性商业银行在银行竞争程度更高的地区设立异地分支机构时,银行效率提高的更多。本文结果对相关文献提供了重要的补充,并为我国区域银行业的发展规划提供了实证依据。     

Financial deregulation and efficiency: An empirical analysis of Indian banks during the post reform period

The paper investigates the performance of Indian commercial banking sector during the post reform period 1992-2002. Several efficiency estimates of individual banks are evaluated using nonparametric Data Envelopment Analysis (DEA). Three different approaches viz., intermediation approach, value-added approach and operating approach have been employed to differentiate how efficiency scores vary with changes in inputs and outputs. The analysis links the variation in calculated efficiencies to a set of variables, i.e., bank size, ownership, capital adequacy ratio, non-performing loans and management quality. The findings suggest that medium-sized public sector banks performed reasonably well and are more likely to operate at higher levels of technical efficiency. A close relationship is observed between efficiency and soundness as determined by bank's capital adequacy ratio. The empirical results also show that technically more efficient banks are those that have, on an average, less non-performing loans. A multivariate analysis based on the Tobit model reinforces these findings.     

Schumpeterian competition and efficiency among commercial banks

In this paper, we aim to fill the gap in the banking literature by quantifying the impact that the Schumpeterian competition mode – i.e. competition through the launch of new products (or new varieties of products) – has on the cost and profit efficiency of a sample of commercial banks based in the United Kingdom. We estimate both a cost and an alternative profit frontier on an unbalanced panel of UK commercial banks over the period 2001–2012. The intensity of competition through product innovation is proxied by the trademark intensity (i.e. the ratio between the number of trademarks registered in a given year by all the commercial banks – net of the trademarks registered by the bank under observation – and the employment in the sector) in the commercial banking sector. Our results show that the (lagged) trademark intensity in the commercial banking sector does affect negatively the mean cost and profit efficiency in the sector but there is evidence that as trademark intensity increases in the sector, commercial banks react by improving their cost and profit efficiency.     

政策连续性与商业银行系统性风险

本文基于2007年第一季度至2019年第四季度中国A股32家上市银行非平衡面板数据,从“冲击”和“传染”两个维度考察了政策连续性对银行系统性风险的影响。实证结果表明,政策连续性程度的提高通过降低银行个体风险和减弱银行个体与系统的关联性进而显著降低了银行系统性风险。进一步分析发现,政策连续性降低了银行被动风险承担水平而非主动风险承担意愿,减弱了银行间接关联程度而非直接关联程度。异质性分析表明,经济下行和货币宽松时期,政策连续性对系统性风险的降低效应更大,并且本身破产风险越高、信息透明度越低的银行,其系统性风险受政策连续性的影响越大。区分不同类型的政策发现,货币政策、财政政策、汇率与资本项目政策的连续性上升均能显著降低银行系统性风险,其中货币政策连续性对银行系统性风险的影响力度最大。     

我国商业银行的效率现状及生产率变动分析

本文运用数据包络分析方法和Malmquist指数对我国28家三类商业银行2000～2004年的技术效率、纯技术效率和规模效率以及全要素生产率变动进行了测算。结果发现,三类商业性银行的效率存在差异:国有商业银行的规模效率最低,并且呈规模报酬递减;股份制商业银行效率略高于国有商业银行;城市商业银行效率由相对最低转为相对最高。总体上看,银行业全要素生产率呈上升趋势,技术效率呈下降趋势,规模效率无明显变化。本文的主要结论是:规模是影响国有商业银行和股份制商业银行效率差异的主要因素,银行全要素生产率的变动受信息技术发展的推动以及宏观环境的影响。     

Market concentration and bank competition in emerging asian countries over pre and post the 2008 global financial crisis

This paper examines the relationships between market concentration, bank competition, and efficiency in banking across six emerging Asian countries namely Bangladesh, India, Indonesia, Malaysia, the Philippines and Vietnam over the period 2005 to 2012. The countries selected for this study operate commercial banking activities with a comparatively large number of both publicly listed and private commercial banks providing a broad range of commercial banking services. For example, banks in Bangladesh, India and Vietnam used to be predominantly state-owned. But over the last few decades, governments have been issuing licenses to private owners. The methodological approach taken by our study provides an important and original contribution to the extant literature by testing various hypothesis that investigate the relationship between competition and efficiency across banks from a select group of Asian countries. We find that market concentration has a positive effect whereas competition has a negative effect on the efficiency of banks operating in these countries. This finding conveys a critically important message to the regulators of banks in these countries: there is a trade-off between quantity and quality. Our analyses also reveal that the effect of bank size on efficiency is positive whereas the effect of liquidity risk on efficiency is negative. This again supports the conventional wisdom that large banks are in a position to provide cost efficient services because they have the ability to attain economies of scale and scopes. Here again, the regulators have very important roles to play: while they have to put in place effective mechanism preventing big banks from being an oligarchy; at the same time, they should make sure that banks get liquidity support as funding pressure builds up.     

Bank regulatory capital and liquidity: Evidence from US and European publicly traded banks

The theory of financial intermediation highlights various channels through which capital and liquidity are interrelated. Using a simultaneous equations framework, we investigate the relationship between bank regulatory capital and bank liquidity measured from on-balance sheet positions for European and US publicly traded commercial banks. Previous research studying the determinants of bank capital buffer has neglected the role of liquidity. On the whole, we find that banks decrease their regulatory capital ratios when they face higher illiquidity as defined in the Basel III accords or when they create more liquidity as measured by Berger and Bouwman (2009). However, considering other measures of illiquidity that focus more closely on core deposits in the United States, our results show that small banks strengthen their solvency standards when they are exposed to higher illiquidity. Our empirical investigation supports the need to implement minimum liquidity ratios concomitant to capital ratios, as stressed by the Basel Committee; however, our findings also shed light on the need to further clarify how to define and measure illiquidity and also on how to regulate large banking institutions, which behave differently than smaller ones.     

Credit information sharing in the nexus between charter value and systemic risk in Asian banking

In this paper, we assess whether the link between charter value and systemic risk in banking is affected by credit information sharing at the country level. Using a sample of Asian listed banks, we document that banks with higher charter value exhibit lower systemic risk because these banks hold more capital. Nevertheless, we find that the self-disciplining role of charter value in banking is more pronounced for countries with lower depth of credit information sharing. Specifically, our findings also reveal that higher charter value alleviates systemic risk and increases capitalization, particularly in countries with lower quality of private credit bureaus. These findings suggest that higher charter value can be detrimental for financial stability due to an increase in bank systemic risk, particularly when private credit bureaus are of better quality. In order to overcome bank systemic risk, this paper advocates the importance of strengthening bank competition to limit charter value, in addition to promoting the development of private credit bureaus.     

Regional economic development,strategic investors,and efficiency of Chinese city commercial banks

We investigate the effect of strategic investors on bank efficiency in the context of regional economic development. The data on Chinese city commercial banks operating regionally are well-suited for the study. Our findings suggest that strategic investors significantly increase efficiency in Chinese city commercial banks, while the effect of strategic investors on the efficiency of Chinese city commercial banks is negatively correlated to the level of regional economic development. The negative correlation of the effect of strategic investors on Chinese city commercial banks’ efficiency with regional economic development may be explained by the mix of local official promotion system and city commercial banks’ governance structure.

金融科技布局、银行信贷风险与经营绩效——来自商业银行与科技企业战略合作的证据

商业银行通过布局金融科技进行的金融服务创新,已成为深化金融供给侧结构性改革的重要举措。本文通过手工搜集2005—2019年323家商业银行与科技企业战略合作的数据,研究银行布局金融科技如何影响其信贷风险与经营绩效。结果表明:(1)银行布局金融科技战略能降低银行信贷风险,提高银行经营绩效;(2)银行布局金融科技通过提高其自身创新能力与竞争力从而降低银行的信贷风险水平;(3)银行布局金融科技,通过降低信贷风险、提升普惠金融服务、提高运营管理能力与拓展中间业务这四个渠道提高了银行经营绩效;(4)全国性银行发展金融科技使其信贷风险水平得到降低,资本充足率低的银行通过布局金融科技降低信贷风险的效果更强。同时,信用贷款比重越高的银行通过发展金融科技降低信贷风险、提高经营绩效的效果更加明显。本文研究有助于理解商业银行顺势而为所进行的金融科技布局的微观经济后果,也为进一步完善金融服务实体经济相关政策提供参考。     

Banks' Liquidity and the Cost of Liquidity to Corporations

We consider the liquidity shock banks experienced following the collapse of the asset‐backed commercial paper (ABCP) market in the fall of 2007 to investigate whether banks' liquidity conditions affect their ability to provide liquidity to corporations. We find that banks that borrowed more from the Federal Home Loan Bank system or the Federal Reserve's discount window following that liquidity shock passed a larger portion of their borrowing costs onto corporations seeking access to liquidity when compared to the precrisis period. This increase is larger among banks with a bigger exposure to the ABCP market, credit lines that pose more liquidity risk to banks, and borrowers that are likely dependent on the credit‐line provider. Our findings show that the crisis that affected the banking system had a negative effect not only on the price of credit to corporations, but also on the price corporations pay to guarantee access to liquidity.     

Bank funding structures and risk: Evidence from the global financial crisis

This paper analyzes the evolution of bank funding structures in the run up to the global financial crisis and studies the implications for financial stability, exploiting a bank-level dataset that covers about 11,000 banks in the U.S. and Europe during 2001–09. The results show that banks with weaker structural liquidity and higher leverage in the pre-crisis period were more likely to fail afterward. The likelihood of bank failure also increases with pre-crisis bank risk-taking. In the cross-section, the smaller domestically-oriented banks were relatively more vulnerable to liquidity risk, while the large cross-border (Global) banks were more vulnerable to solvency risk due to excessive leverage. In fact, a 3.5 percentage point increase in the pre-crisis capital buffers of Global banks would have caused a 48 percentage point in their probability of failure during the crisis. The results support the proposed Basel III regulations on structural liquidity and leverage, but suggest that emphasis should be placed on the latter, particularly for the systemically-important institutions. Macroeconomic and monetary conditions are also shown to be related with the likelihood of bank failure, providing a case for the introduction of a macro-prudential approach to banking regulation.     

Differential impact of Korean banking system reforms on bank productivity

We study the impact of banking system reforms during a crisis following a period of undisciplined lending. Regulatory changes aimed at strengthening the banks’ capital structure and risk management practices do not have a uniform impact on bank productivity, but rather favor financially sound or strategically privileged banks. We present evidence documenting the differential impact of regulatory reforms on Korean commercial bank productivity over the period 1995–2005. Average technical efficiency of banks decreased during the financial crisis of 1997–1998. It improved following the subsequent bank restructuring and continued to improve through 2005. The capital adequacy ratio is positively associated with banks’ technical efficiency. The non-performing loans ratio is negatively associated with technical efficiency. Both relationships are accentuated during the crisis but attenuated after the reforms.     

Bank efficiency in emerging Asian countries

The paper examines the relationships between market concentration, bank competition and X-efficiency in banking across six emerging Asian countries—Bangladesh, India, Indonesia, Malaysia, the Philippines and Vietnam—over the period 2005–12. Market concentration has a positive effect on X-efficiency, whereas competition has a negative effect on X-efficiency. Moreover, bank size and gross domestic product growth have positive influences on X-efficiency whereas liquidity risk is negatively related to X-efficiency. In addition, the study has important policy implications for governments and banks with respect to increasing X-efficiency of banking.     

How does competition affect bank systemic risk?

Using bank level measures of competition and co-dependence, we show a robust negative relationship between bank competition and systemic risk. Whereas much of the extant literature has focused on the relationship between competition and the absolute level of risk of individual banks, in this paper we examine the correlation in the risk taking behavior of banks. We find that greater competition encourages banks to take on more diversified risks, making the banking system less fragile to shocks. Examining the impact of the institutional and regulatory environment on bank systemic risk shows that banking systems are more fragile in countries with weak supervision and private monitoring, greater government ownership of banks, and with public policies that restrict competition. We also find that the negative effect of lack of competition can be mitigated by a strong institutional environment that allows for efficient public and private monitoring of financial institutions.     

Economic value,competition and financial distress in the European banking system

In this paper we examine the impact of a large number of factors at the bank level (liquidity and credit risks, asset size, income diversification and market power), at the industry level (banking concentration) and macro-level (real GDP growth) on bank financial distress using an unbalanced panel of 308 European commercial banks between 1996 and 2009. The observations falling below a given threshold of the empirical distribution of the Shareholder Value Ratio proxy bank financial distress. We employ a panel probit regression and, given the presence of overlapping data giving rise to residual autocorrelation, we use the Bertschek and Lechner (1998) robust estimator of the covariance matrix of parameters. We show that credit risk, liquidity risk and bank market power are the most influential determinants of distressed Shareholder Value Ratio. Finally we evaluate the model out-sample forecasting performance over the 2008–2009 crisis period.     

Can fintech improve the efficiency of commercial banks? —An analysis based on big data

This paper assess the potential impact of Fintech on the banking industry. Results suggest that, for commercial banks, development of Fintech leads to increased profitability, financial innovation, and improved control of risk. Overall, by using financial technology, commercial banks can improve their traditional business model by reducing bank operating costs, improving service efficiency, strengthening risk control capabilities, and creating enhanced customer-oriented business models for customers; thereby improving comprehensive competitiveness. We also find that levels of such outcomes vary with levels of respective bank’s use of technological innovation.
