银行业市场结构对企业生产率的影响——来自工业企业的经验证据

本文在充分考虑中国信贷市场本地竞争特征的基础上,利用手工收集的商业银行分支机构独特数据构造了城市层面的银行业市场结构指标,并将其与2002-2007年中国工业企业数据库进行合并构造基础数据库,考察了银行业市场结构对企业生产率的影响。研究发现:首先,一个更具竞争性的银行业市场结构显著提高了企业生产率,这支持了银行业市场结构的“市场力量假说”;其次,从影响机制来看,一个更具竞争性的银行业市场结构更有利于缓解企业面临的融资约束;最后,银行业市场结构对企业生产率的影响在那些面临更多融资约束的企业中更为显著,小企业、非国有企业、新企业和高技术行业的企业从银行业竞争中获益更大。     

中国银行业结构性全要素生产率增长研究

在深化银行业供给侧结构性改革背景下,如何科学评价银行业的结构性全要素生产率(TFP)增长具有重要意义。区别于早期针对个体样本的技术性TFP增长研究,本文通过构建并分解加总的Luenberger生产率指标对我国银行业以及不同类型银行的结构性TFP增长及来源进行有效评价。结果显示,研究期间,我国银行业的结构性TFP增长表现良好,其中,整体技术进步是主要驱动力;进一步分解发现,制度创新改善和加总的个体技术进步推动了银行业结构性TFP增长。在整体效率变化方面,加总的个体技术效率变化和结构效率变化都有待提高,其中,范围效率变化是抑制结构效率改善的主要因素。考虑不同类型银行,制度创新变化对所有类型银行的结构性TFP增长都影响显著,加总的个体技术变化对股份制和地区性银行的结构性TFP增长贡献更突出;加总的个体技术效率变化、结构效率变化、范围效率变化和规模效率变化对不同类型银行的结构性TFP增长作用有限。     

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。     

How does greater bank competition affect borrower screening? Evidence from China's WTO entry

We analyze the relationship between greater bank competition and the screening of potential borrowers. Using a large sample of Chinese private firms and China's entry into the WTO as a unique setting leading to greater bank competition, we find the following. First, the sensitivity of bank credit to prior borrowing-firm performance increases after China's WTO entry. This sensitivity increase is greater in more bank-dependent industries and smaller in Chinese regions with greater financial sector development. Second, the increase in the sensitivity of bank credit to firm performance is much greater for state-owned firms compared to private firms. Third, the effect of bank credit on subsequent firm productivity and performance is greater for loans given after China's WTO entry compared to those given prior to WTO entry. Overall, the results of our empirical analysis suggest that the stringency of bank screening of borrowers in China increased with greater banking sector competition.     

Productivity,technology and efficiency of De Novo Islamic banks: Empirical evidence from Malaysia

The impact of foreign banks’ entry on the conventional banking sector has been well documented in the literature. However, empirical evidence on the impact of foreign banks’ entry on the Malaysian Islamic banking sector is completely missing from the literature. By employing the Malmquist Productivity Index method, the article provides, for the first time, empirical evidence on the impact of foreign banks’ entry on the efficiency and productivity of the Islamic banking sector. The empirical findings indicate that the De Novo foreign Islamic banks have been relatively more efficient and productive compared to their domestic and foreign Islamic bank counterparts. The results also suggest that the Malaysian Islamic banking sector has exhibited a higher level of total factor productivity during the post De Novo foreign Islamic banks’ entry period.     

Bank efficiency,productivity, and convergence in EU countries: a weighted Russell directional distance model

The objective of this study is three-fold. First we estimate and analyse bank efficiency and productivity changes in the EU28 countries with the application of a novel approach, a weighted Russell directional distance model. Second, we take a disaggregated approach and analyse the contribution of the individual bank inputs on bank efficiency and productivity growth. Third, we test for convergence in EU28 bank productivity as well as in the inefficiency of individual bank inputs. We find that bank efficiency has been undermined by the financial crisis in banks notably from the EU15 countries. We also argue that bank efficiency and productivity in EU countries vary across the banking sector with banks from the ‘old’ EU showing higher efficiency levels. Nonetheless, a noticeable catching up process is observed for banks from the ‘new’ EU countries. Consequently, we do not find evidence of group convergence for bank productivity but there is evidence of convergence in bank efficiency change and technical change among the EU28 countries throughout the period 2005–2014. The driving force seems to be convergent technical change from the old EU member states’ banks. On the other hand, almost no convergence is detected for the banks’ individual inputs while the transition paths show heightened diversity during the crisis years.     

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.     

Bank globalization and efficiency: Host- and home-country effects

Analyzing 126 countries for 1995–2013, we investigate the link between bank globalization and efficiency from the perspective of both host and home countries. We find strong and consistent evidence that foreign bank entry is associated with lower efficiency in host countries (host-country effect), while foreign expansion in the banking sector improves the efficiency of banks at home (home-country effect). We further observe that the effect of bank globalization is dependent on the regulatory and institutional regimes of the respective host (home) countries. Specifically, stringent activity restrictions, tight supervision, fewer limitations on foreign banks, lower market entry barriers, and less government interference all help mitigate the efficiency loss from foreign bank entry. Less supervision power, multiple supervisors, more restrictions on foreign banks, and a competitive banking market are all conducive to the higher efficiency gain of incumbent domestic banks from the respective country’s outward investments in the banking sector. Moreover, we find that the adverse impact on efficiency from foreign bank presence is less pronounced for less risky, more profitable, and larger banks, while banks that are more efficient, more profitable, taking on more risk, and/or smaller gain more efficiency from their country’s foreign expansion.     

Exploring the nexus between financial sector reforms and the emergence of digital banking culture – Evidences from a developing country

Several financial and banking sector reform programs were instituted in different countries over the last three decades. The underlining purpose of these reforms was largely to improve banking sector supervision and regulation, introduce bank privatization mechanism, introduce clearance and settlement systems, infuse competition and to stimulate financial innovation. The objectives of this study are to 1) review the relevant published literature and market survey reports on the financial & banking sector reforms undertaken in Pakistan and elsewhere, 2) analyze how these reform programs develop digital banking culture and increase financial inclusion in the country and 3) guide future research by putting forward a research agenda. The findings of the study suggest a link between the financial and banking sector reforms and the stimulation of financial innovation; the promotion of digital banking culture; and the infusion of financial inclusion in Pakistan. We discuss managerial/policy implications of the study, limitations and presents recommendations for future research.     

The impacts of risk-taking behaviour and competition on technical efficiency: Evidence from the Chinese banking industry

This paper tests the impact of risk and competition on efficiency in the Chinese banking industry over the period 2003–2013. Comprehensive types of risk-taking behaviour are considered including credit risk, liquidity risk, capital risk, and insolvency risk. Competition is measured by the Lerner index. The results are cross-checked using an alternative econometric technique as well as an alternative competition indicator. The findings show that the technical and pure technical efficiencies of Chinese commercial banks are significantly and negatively affected by liquidity risk. They further show that greater competition precedes declines in technical and pure technical efficiencies of Chinese commercial banks. The results suggest that Chinese bank efficiency is significantly affected by bank diversification, banking sector development, stock market development, inflation and GDP growth rate. The findings also indicate that, compared to state-owned commercial banks, joint-stock commercial banks and city commercial banks have lower technical and pure technical efficiencies.     

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。     

Efficiency and productivity growth in the banking industry of Central and Eastern Europe

We employ the directional technology distance function and provide estimates of bank efficiency and productivity change across Central and Eastern European (CEE) countries and across banks with different ownership status for the period 1998–2003. Our results demonstrate the strong links of competition and concentration with bank efficiency. They also show that productivity for the whole region initially declined but has improved more recently with further progress on institutional and structural reforms. Input-biased technical change has been consistently positive throughout the entire period suggesting that the reforms have induced favorable changes in relative input prices and input mix. However we find evidence of diverging trends in productivity growth patterns across banking industries and that foreign banks outperform domestic private and state-owned banks both in terms of efficiency and productivity gains. Overall, we find that productivity change in CEE is driven by technological change rather than efficiency change.     

Cost efficiency of the banking industry in the South Eastern European region

This paper analyses cost efficiency in the banking sector of six South Eastern European countries over the period 1998–2003. A stochastic frontier approach, incorporating firm-specific and country-related variables, indicates a generally low level of cost efficiency, with significant inefficiency differences among countries. Foreign banks and banks with higher foreign bank ownership involvement are associated with lower inefficiency. Furthermore, we observe a negative correlation of cost inefficiency with bank capitalization and firm market share, and a positive one with the fraction of loans in the asset portfolio.     

存款保险、市场竞争与银行经营稳健性

本文基于银行存款市场空间竞争模型,探讨存款保险制度的实施效果和福利效应,及其与市场竞争政策的交互作用。研究表明,政府隐性担保尽管能够保障存款人利益,但会降低存款人对银行经营稳健性的要求,使得银行追求高风险高收益资产从而降低经营稳健性;而市场化的存款保险制度通过费率与风险挂钩的激励机制,能够有效提升银行经营稳健性,同时避免过高政策成本负担,实现较高的社会福利水平。随着市场竞争强化,引入风险差别费率保险制度,在提升银行经营稳健性和增进社会福利方面的效果逐渐增强。模型分析表明,当长期允许机构自由进出市场时,政府强化竞争政策短期可能降低银行的经营稳健性,但长期内高风险银行逐渐退出市场而更有效率的低风险银行进入市场,这种柔性市场退出机制使得银行业整体经营稳健性增强。因此,在金融市场中强化竞争政策,推行并完善当前市场化的风险差别费率存款保险制度,长期内有助于在保护存款人利益的同时,提升银行稳健性和社会福利。     

The sources of bank productivity growth in China during 2002–2009: A disaggregation view

This study investigates the sources of bank productivity growth in China over the period 2002–2009. In order to perform this research, we propose an advanced index – input slack-based productivity index (ISP) – a model that disaggregates total factor productivity growth into each input productivity change. Funds, capital, and employees are chosen as the inputs, whereas loans and other earning assets are outputs in this study. Our results show that technological gains transcend the efficiency regressions and result in total factor productivity growth. More specifically, technical progress in capital productivity reveals the dominant force behind the total factor technical change and productivity improvement. In addition, this paper uses these disaggregation terms to find out the competitive advantages and disadvantages of input usages for each Chinese bank. These findings indicate that the ISP index provides more insights than traditional total factor productivity indices.     

Contraste de la ley de Gibrat en la banca comercial brasileña

In recent years Brazil has been one of the countries with major changes in the banking sector. The deregulation process that has taken place since 2002 has brought an increased presence of foreign banks and higher competition, among other aspects. In this context, the objective of this study is to analyze Gibrat's law on Brazilian commercial banks over the period 2002-2013 with the aim of providing evidence for the construction of a banking growth model which guide the country's financial policy. To that end, we employ a methodology based on quartile regressions as a contribution to previous literature. Our overall results reveal the existence of a non-lineal relationship between growth and banks size with an inverted U-shape. These findings allow us to affirm that the relative dispersion of banks size, as well as the sector's concentration, will be reduce in the future years.     

Factors influencing the performance of foreign-owned banks in New Zealand

This article reviews factors affecting the performance of foreign-owned banks in New Zealand, where they control 99.2% of all banking system assets. Two sets of pooled cross-sectional time-series data—seven banks over the 10-year period 1991–2000 and eight banks over the 8-year period 1991–1998—provided the basis for the econometric analysis. The most important variables for bank performance were the length of time the foreign bank had been in New Zealand and the parent bank's return on assets. This suggests that parent-bank specific ownership advantages are the dominant factor in their subsidiaries’ performance in New Zealand.     

Productivity and Technical Change in Malaysian Banking: 1989–1998

This study examines the impact of deregulation and technological change on the productivity of Malaysian banks over the period 1989–1998. Malmquist indices constructed with nonparametric DEA techniques are decomposed into their pure efficiency, scale efficiency, and technological change components. Our findings indicate an erosion of banking productivity that masks divergent tendencies among its component elements. These are dominated by adverse effects of technological change, which are associated with a reduction in the labor intensity of banking activity. Consistent with the mixed findings reported in the literature, the present investigation suggests that regulatory reform and liberalization are not sufficient conditions for productivity improvement.JEL classification: D24, G21This paper was written while Dogan was a member of Monash University Malaysia.

Bank privatization in developing countries: A summary of lessons and findings

Although a large and growing literature shows that privatization can improve the performance of non-financial enterprises, there is less evidence on how it affects the performance of the banking sector. This paper summarizes the results from the papers in the special issue of the Journal of Banking and Finance on bank privatization. It concludes that although bank privatization usually improves bank efficiency, gains are greater when the government fully relinquishes control, when banks are privatized to strategic investors, when foreign banks are allowed to participate in the privatization process and when the government does not restrict competition.     

关于中国经济增长模式的一个解释框架--基于“土地财政”的演进分析北大核心

本文建立了一个新的模型尝试解释中国经济的近中期增长模式。在考虑“土地财政”作用的基础上,首先建立两期世代交叠(OLG)模型说明基本原理,随后将两期模型扩展到多期OLG模型,进行参数校准和模型求解。研究表明,在城镇化过程中政府将通过“土地财政”机制获得的资本用于基础设施建设,使得企业部门资本重新配置、均衡条件重构,推动形成国有企业与民营企业相对占比的稳定均衡。在这一机制下,GDP和全要素生产率不断上升但增速逐渐下降;资本的总体投资效率和资源配置优化速度出现下降,民营企业占比先增后稳。多期模型较好地刻画了我国1998—2017年期间经济结构变化趋势以及储蓄率、投资率、对外投资与外汇储备等宏观指标。随着“土地财政”作用的进一步弱化,持续推动技术进步、深化国企改革、深化金融改革等是实现我国经济长期可持续发展的关键举措。
