银行垄断与银行危机

银行垄断不必然产生无效率，更不用说银行危机了。但是这一状况却出现在我国的四大专业银行上。在这篇文章里，作者指出，由于我们在国有银行作用定位上的错误，强使它们承担了许多本不属于它们的社会和政治的义务，从主观和客观两方面确定了其垄断地位，因此产生了许多严重的问题，如资本金不足，技术上的破产等，尤其是潜在的银行危机。     

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.

数字蜂窝式移动电话系统现状与发展

目前在世界上许多国家运营的蜂窝式移动电话系统如北欧四国的 NMT、美国的AMPS、联邦德图的 C 网、英国的 TACS、日本的 NAMTS,我国在北京、上海和广州运营的 TACS 和爱立克森系统都属第一代模拟式移动电话系统。为了满足更多用户的要求,建立符合统一技术标准的系统,欧州许多国家在移动通信专业组(GSM)组织协调下,提出了多种系统方案,即第二代数字蜂窝式移动电话系统试验系统方案。本文对这几种系统,重点对 CD900、S900D,作了全面介绍。并从多址技术、信道编码、语音编码、调制技术以及经济性等方面进行了分析和评估。     

Financial liberalization and banking crises in emerging economies

Financial liberalization often leads to financial crises. This link has usually been attributed to poorly designed banking systems, an explanation that is largely static. In this paper we develop a dynamic explanation, by modelling the evolution of a newly-liberalized bank's opportunities and incentives to take on risk over time. The model reveals that even if a banking system is well-designed, in the sense of having good long-run properties, many countries will enjoy an initial period of rapid, low-risk growth and then enter a period with an elevated risk of banking crisis. This transition emerges because of the way in which the degree of foreign competition, the marginal product of capital, and the bank's own net worth simultaneously evolve.     

Mobile technology usage and B2B market performance under mandatory adoption

This paper investigates the relationship between mandatory adoption of mobile information technology and market performance in the business-to-business (B2B) setting. This study presents and tests the B2B technology satisfaction model (TSM), including perceived loss of control as the mandatory technology acceptance-specific variable. The results of this study reveal that integrating perceived loss of control with user satisfaction and the TAM (technology acceptance model) in a single model can better explain the B2B market performance model. The empirical results suggest that perceived loss of control has a negative effect on user satisfaction and perceived market performance is influenced by user satisfaction and perceived usefulness. Managerial implications of the study are discussed.     

Financial reforms in Chinese banking: The impact on personal lending and operational efficiency

The Chinese financial system has historically been one of secrecy, distrust, and corruption. The process does not align with the western standards of transparency and auditing. In contrast to the transaction-based business culture of the West, Chinese business society is relationship-based (quanxi), which still seems to play a key role in the credit decision. With the growth of the emerging middle class, access to financial instruments such as credit cards, life insurance, stock purchases, and the like will play a greater role in the life of the Chinese consumer. Based on these forecasts, the authors recommend seven actions to manage financial activities in China, all of which are explored within this article.     

国有商业银行上市对银行业效率水平的影响——基于Malmquist生产率指数的实证分析

文章基于我国15家各类性质银行在1996-2010年经营效率数据基础上,利用数据包络分析法(DEA),对我国银行1996-2010年经营效率进行总体评价与分析,报告了我国银行业务经营效率水平。通过应用Malmquist生产率指数对银行业务经营效率变动得进行了调查和测量,结果反映了银行上市后银行业效率提高幅度明显,尤其是国有银行进步最快,但我国商业银行普遍存在规模报酬递减的状况,需要进一步提高规模报酬。从动态上看,我国银行业1996-2003年全要素生产率总体上出现小幅的下降,但2004年以后,随着国有银行逐步上市,我国银行业全要素生产率得到了稳步的提升。笔者认为我国银行需不断拓展表外业务、提高日常管理水平、吸收更多高学历人才和增加新兴技术的自主创新。     

The Panzar–Rosse revenue test and market power in banking

The Panzar–Rosse H statistic is a commonly used measure of market power in banking. It is widely believed that $H>0$ is inconsistent with significant market power. This study rigorously disproves that perception. Instead, the possibility of $H>0$ under conditions of substantial market power turns out robust to the timing of banks’ actions, relative costs, choice of strategic variable, degree of product differentiation, strategy (static or dynamic), and degree of heterogeneity in banks’ conduct (collusive versus fringe), and hence may be common in practice.     

财政存款、银行竞争与僵尸企业形成

银行以优惠利率贷款为低质企业“输血”,是企业僵尸化的重要成因。然而,基于中国背景的文献,对银行“输血”动机的研究并不充分,本文从地方财政存款影响银行信贷分配的视角,分析僵尸企业形成的内在机理。首先,通过构建理论模型对银行竞争财政存款及影响企业融资和投资绩效进而僵尸化的逻辑进行刻画,而后依据省份财政存款、银行竞争与微观企业财务数据,对理论推论进行了验证。研究发现,财政存款占当地存款比重越大,企业僵尸化概率越高,并且银行竞争助长了企业僵尸化。此外,基于工具变量估计处理了核心变量的内生性问题,并进行了多种稳健性检验。机制检验表明,财政存款的信贷分配效应,促使企业过度投资,导致经营绩效恶化,进而提高了企业僵尸化概率,银行竞争则会加剧该效应。本文拓展了财政存款的经济效应与僵尸企业形成方面的文献,对于僵尸企业治理有一定参考意义。
