现代商业银行与资本市场关系的理论分析与实证考察

现代金融体系正在发生结构性变革,资本市场逐渐成为现代金融运行的新平台,迅速发展的资本市场从资产和负债两个方面与传统商业银行形成竞争态势,传统商业银行的地位和作用不断削弱.动态地看,商业银行与资本市场是相互补充的,商业银行通过将业务模式和运行机制建立在资本市场的平台上,进而实现由传统商业银行向现代商业银行的转型.商业银行与资本市场不断竞争又相互补充,提高了金融体系的效率,共同推进现代金融体系的发展.从今后来看,我国商业银行将通过资产证券化为资本市场提供更多的金融产品,通过金融控股公司等模式介入资产管理业务,商业银行与资本市场之间将形成良性的互动关系.     

THE USE OF ACQUISITIONS AND JOINT VENTURES BY U.S. BANKS EXPANDING ABROAD

We examine international bank expansions, which are classified as banking (scale related) or nonbanking (complementary) moves into developed or developing markets. The market responds favorably to expansions through joint ventures by U.S. banks, and insignificantly to expansions through acquisitions. Accounting and operating performances (for joint venture banks) and long‐period holding returns (for acquisitions) show improvement in the two years following the announcement. Systematic risk declines for the sample overall, for acquisitions, and for expansions into developing countries. In general, scale or developing expansions are better pursued through acquisitions, whereas complementary or developed expansions are best pursued through joint ventures.     

消费市场与商业银行的业务创新

我国商业银行推出消费信贷业务是一个顺应潮流的重大战略选择,其意义是多方面的.本文主要使用新古典经济学消费者行为模式和信息经济学的分析方法,借助消费者行为模式对国内消费市场现状从外部设定和内部设定两个方面进行分析,突出了外部设定变化对消费者行为的影响;使用信息经济学分析方法,重点指出了信息不对称是商业银行开展消费信贷的一大基本制约因素,从而论证金融创新必须以如何解决信息不对称为主题.本文的分析结论是:在解决信息不对称问题上,尽管仍离不开政府的作用,但银行的主角地位不容质疑;具体讲,创新的主题是大力推进消费信贷业务并使其尽快形成可盈利的业务规模.     

新兴资本市场业务与银行传统业务的整合与发展

面对加入WTO后全能型外资银行的挑战,国内银行必须以传统业务与新兴资本市场业务的有效整合为突破口,不断进行金融创新,以巩固和发展客户,并通过业务多元化分散经营风险.本文通过对新兴资本市场业务与商业银行传统业务整合内涵、特点和方式的分析,以及对工商银行广东省分行实践的总结,认为实现有效持续的整合,不仅要从战略上把握基本趋势、确定合理方针和与时俱进的原则,而且要从战术上制定切合实际的策略和方案;不仅发展服务于资本市场的派生型、延伸型和交叉型业务,而且要发掘两者之间功能的综合化、证券化业务,使业务整合在层次上得以深化,在内涵上得以升华.     

THE RELATIONSHIP BETWEEN MARKET AND ACCOUNTING BETAS FOR COMMERCIAL BANKS

This study examines the correlation between market equity betas and accounting asset and equity betas in the commercial banking sector. A sample of banks was taken from the COMPUSTAT tapes and annual equity and asset accounting betas (calculated with various indices) were estimated over varying time periods. Cross-sectional correlations were then determined for individual banks and five-bank portfolios. The results indicate that the correlations are comparable to those found in other non-banking studies of accounting and market betas. A noticeable difference in our study was the sensitivity of the correlations to the length of the estimation interval for the betas. The longest estimation intervals (16–18 years) produce few significant correlations in our sample. These correlations were significantly lower than those obtained using fifteen or fewer years of data. Construction of portfolios generally increases all the correlations but the longer time period correlations are still significantly lower. The correlations are largely invariant, however, to the choice of index used in the estimation of the betas.
