不良贷款约束下的中国银行业全要素生产率增长研究

本文运用共同边界Malmquist-Luenberger生产率指数测度了2004—2009年中国27家商业银行在不良贷款约束下的全要素生产率增长及其成分,并对影响全要素生产率增长的宏观经济因素进行了实证分析。本文的主要结论有:在表示偏离共同边界的技术落差比率方面,国有商业银行呈"V"型,股份制商业银行较平稳,城市商业银行逐步上升;总体上,中国银行业的全要素生产率是进步的,纯技术进步是推动全要素生产率进步的主要动力,纯技术效率变化和规模效率变化进步都不明显,技术规模变化显示中国银行业趋向CRS边界;股份制商业银行的纯技术赶超最优,而潜在技术相对变动方面表现较弱;外资银行进入和固定资产投资增加对银行全要素生产率提高有推动作用。     

Productivity changes in pre-crisis Western European banks: Does scale effect really matter?

Insofar as the completion of the Single Market for Financial Services, it has presented new challenges for European Banking industries. In this study, we use a recently developed generalized metafrontier Malmquist productivity index (gMMPI) to provide insights on productivity growth. We extend the gMMPI to broaden the index's capacity by decomposing various sources of productivity change in the metafrontier context. The sample contains commercial banks from 12 Western European countries prior to the recent financial crisis. A key advantage of our extension is that it introduces the role of scale effects. The empirical results show that an average bank's productivity growth arises mainly from technical changes and scale effects. Moreover, smaller and larger banks grow faster than medium ones. In addition, conservative banks tend to grow faster. These findings suggest that a more competitive and integrated financial market induced by financial deregulation is indeed able to improve banks’ productivity.     

海峡两岸证券业经营效率比较研究:基于Metafrontier方法

本文将Metafrontier思想与BCC-DEA模型相结合,综合应用Metafrontier DEA方法、Malmquist全要素生产率指数和Tobit模型,客观地评价具有不同生产技术的两岸证券商的经营效率。结果表明:台湾证券商发展水平趋同,大陆证券商良莠不齐,但竞争力逐渐提升;台湾证券商技术水平落后于大陆;大陆全要素生产率逐渐改善,台湾逐渐衰退;资产总额、负债比、地区生产总值是影响技术效率的关键因素,负债比、经济自由度、地区生产总值是影响技术落差的关键因素;金融危机对两岸证券业冲击显著。     

Hotel efficiency: A bootstrapped metafrontier approach

This paper introduces the metafrontier concept to account for the environmental and technological differences between various hotels groups. The interesting feature of the model is that it ensures that heterogeneous hotels are compared based on one homogenous technology. We test the model using a panel data sample of 78 Taiwanese hotels. The results clearly indicate that the size, ownership, and classification of a particular hotel have a significant impact on its efficiency. More implications of the results are provided.     

Accounting for size in efficiency comparisons of airports

This paper adopts the metafrontier model to analyze and compare the technical efficiency of small and large UK airports. The interesting feature of the model is that it takes into account the technological differences in the estimation of efficiency, and thus increases the accuracy in the efficiency comparison between heterogeneous airports. Results show that large airports are generally more technically efficient and have less operational wastage than small airports. Along with size, factors such as location, technological access, and capital investments could contribute to the efficiency difference between small and large airports.     

Technology gaps in European banking: Put the blame on inputs or outputs?

This paper investigates the production efficiency of 12 European banking systems over the period 1997–2004, taking into account possible technology heterogeneity. Using a non-parametric metafrontier framework, efficiency and metatechnology ratio measures are computed and decomposed into input- and output-invariant components. Empirical findings indicate the existence of significant and rather increasing technology heterogeneity within European banking. A typology of the national banking systems is also developed, based on the overall productive performance with respect to the European technological edge, the absorptive capacity and the role of knowledge spillover effects. Decomposition results draw attention to catching up policies focusing on input and/or output scale adjustments.     

Evaluating the efficiency of Korean festival tourism and its determinants on efficiency change: Parametric and non-parametric approaches

Local festivals may leverage local specialties and various historical, cultural, and artistic resources throughout their respective regions to attract tourists, inducing positive economic impacts. In this study, this paper is a first attempt to analyze the relative efficiency of local festival tourism by using parametric and non-parametric approaches with the data from local festivals held in Korea from 2015 to 2018. We also deal with the efficiency determinants of each typology of festivals by employing a truncated regression with double bootstrapping. Results showed that the leading sources of inefficiency were primarily embedded in pure technology inefficiency, while the principal operational drivers posed different effects depending on the typology of festivals. These insights have important practical implications for the local festival organizing committees and operators in Korea and are helpful in developing tailored operational strategies to maximize the efficiency among different typologies of festivals.     

中国电力产业区域技术效率及其影响因素分析

文章基于Metafrontier生产函数模型,采用中国31个省市2000-2010年的面板数据,对电力产业区域技术效率进行了比较分析,并利用托宾模型分析了电力产业区域技术效率的主要影响因素。结果表明：中国电力产业区域技术效率具有40%左右的改进空间,且东、中、西地区的电力产业技术效率呈收敛趋势。相比而言,东部和西部地区电力产业技术效率高于中部。此外,工业比重、技术进步、开放程度等因素对电力产业区域技术效率具有正面的促进作用,而经济规模对电力产业区域技术效率具有负面作用。     

Outward foreign direct investment and technical efficiency: Evidence from Taiwan's manufacturing firms

This paper uses firm-level panel data from Taiwan's manufacturing industries from 1987 to 2000 to investigate the impact of outward foreign direct investment (OFDI) on the technical efficiency of the OFDI firms. Propensity score matching is used to construct an appropriate group of non-OFDI firms to compare with OFDI firms, and a metafrontier framework is subsequently used to calculate comparable technical efficiencies for both groups of firms. Our empirical results reveal that the technical efficiencies of Taiwan's manufacturing firms were increasing over the entire sample period. In addition, our results suggest that the technological advances and the technical efficiency of Taiwan's manufacturing firms are positively correlated with their OFDI activity.
