香港股市与内地股市的联动性研究

本文分3个阶段考察了香港回归以来,香港股市和内地股市之间的联动关系及其变化。协整分析表明,香港股市和内地股市之间存在长期的均衡关系,这种均衡关系在内地资本市场实行股权分置改革后更趋于稳定。Granger因果检验表明,香港回归以来香港股市和内地股市之间的引导关系在经历B股开放和股权分置改革后发生了变化。脉冲响应函数分析从动态的角度进一步验证了香港股市和内地股市之间的引导关系及其变化,并深入分析了单个变量的波动或冲击对其自身及另一变量的影响程度。

Equity returns,bond returns,and the equity premium in the German capital market

This article reviews the empirical evidence for equity returns, bond returns, and the equity premium in the German capital market for the period from 1870 to 1995. Taken together, the studies reviewed provide convincing evidence that over longer investment periods, average equity returns have been higher than average bond returns. These excess returns, however, have been highly volatile and negative in many years, illustrating the higher risk of equity investments. Moreover, market timing had a major positive or negative impact on overall returns. Despite the historical evidence of a substantial equity premium there is still little equity investment by German households.     

股票场外交易市场的制度构建应遵循五项原则

在后创业板时代,应当构建股票场外交易市场制度体系以推动其迅速发展。本文认为,股票场外交易市场制度应当遵循法律定位的差异化、上柜企业的平民化、投资者的机构化、交易方式的创新化、监管制度的高效化这五项原则。     

我国股票市场发展对银行间市场的影响

股票市场和银行间市场是我国金融市场中两个主要的子市场,随着金融市场发展和创新步伐加快,两者之间的关系日益密切。在近年来我国股票市场快速发展的背景下,研究股票市场发展对银行间市场的影响,有助于理顺和改进我国股票市场与银行间市场相互间的关系,促进两个市场协调健康发展。     

The long-horizon returns behaviour of the Portuguese stock market1

In the last few years several research studies have challenged the traditional weak-form efficiency tests of the stock market. These studies suggested an alternative to the random walk model, containing temporary and permanent components. If stocks follow such a model then the traditional tests, using returns computed for short intervals would be unable to detect them. To investigate the evidence for such models in the Portuguese stock market ten stock indexes were created. This is a pioneer study of the Portuguese stock market, and uses nominal, real and excess returns, computed for longer horizons. Three methodologies were used: variance ratios, ordinary least squares regressions and weighted least squares regressions. The statistical significance of the results was studied using traditional parametric tests as well as non-parametric tests. The evidence is mixed, as the presence of tendencies towards mean aversion and mean reversion were detected. Results also show that the evidence is very sensitive to the methodology used and the signifcance tests performed. These results, however, do not necessarily reject the weak-form market efficiency hypothesis.     

产品市场势力、公司治理与股票市场流动性

本文实证研究了我国股票市场的流动性问题。结果表明,产品市场势力能够促进信息传递,提高股票的流动性。这种影响即使控制了公司治理因素依然显著,同时随着信息不对称程度的提高而更为明显。另外,在对股票流动性的影响上,产品市场势力与董事会规模、高管薪酬激励之间存在替代关系。同时,股权分散能增强产品市场势力的影响,但是产品市场势力会削弱股权分散的积极作用。     

股指期货市场金融加速器效应的实证分析

金融加速器理论认为,由于存在着摩擦成本,金融市场的波动可能是非对称的,体现为相对于扩张金融市场状态,紧缩金融市场状态下冲击的波动更加剧烈,由此产生加速效应。本文采用向量自回归模型系列对次贷危机期间S&P500股指期货市场波动状态进行了计量检验,验证了其非对称波动的金融加速器效应,揭示了股指期货市场与股票现货市场之间的风险衍生机制,旨在为我国沪深300指数期货交易的风险防范提供借鉴。     

我国股票市场和房地产市场对货币流速的影响

探讨股市和房市对货币流速的效应是对货币流速影响因素进行实证研究的一个方向。实证结果表明,我国股市、房市变量与狭义货币流速、广义货币流速均存在长期均衡关系,且与货币流速负相关,狭义货币流速主要受股市影响,广义货币流速主要受房市影响。股市和房市导致货币流速下降的原因,有助于解释我国的一些经济现象,同时也提醒我们应进一步规范股市和房市的发展,央行制定货币政策时应该考虑股市和房市对货币需求的影响,要采取预防性货币政策,保持经济与金融的稳健运行。     

我国股票型基金投资行为的实证分析

羊群行为是股票市场中投资者行为的重要方面。本文以我国公募股票型投资基金为分析对象,对2007—2008年的数据进行HM值的整体检验和收益检验,得出了我国股票型投资基金羊群行为的投资特征,并对产生羊群行为的原因进行了探讨,最后提出了改善基金投资行为的若干政策建议。     

我国股票市场与国际市场的联动性研究——对次贷危机时期样本的分析

本文通过构建回归模型,考察了次贷危机前后我国股票市场与世界股票市场联动性的动态变化过程,并且与巴西股票市场进行了比较分析,从而对我国市场与国际市场的互动进行了客观的评价。实证结果表明,总体上我国股票市场与国际市场的联动性不强,并且时而为"即期联动",时而为"滞后联动",联动方式不确定。然而,次贷危机发生后.我国与国际市场的联动性有逐渐增强的趋势,尤其是与英国、香港地区等市场的联动在不断提高。这主要是由于次贷危机使国内外投资者的预期形成机制和投资理念发生了变化。     

股票市场对货币政策传导机制影响的实证研究——基于脉冲响应函数和方差分解的技术分析

随着股票市场的蓬勃发展及其与国民经济的联系日益密切,货币政策的传导机制和效应必然受到股票市场发展的影响,同时股票市场也逐渐成为货币政策传导的重要渠道之一。本文首先对货币政策的传导机制与股票市场的关联机制进行分析,然后运用协整分析、向量自回归模型(VAR)、向量误差修正模型(VECM)、脉冲响应函数、方差分解技术等计量方法对我国股票市场对货币政策传导机制的影响进行了实证分析。结果显示股票市场已经成为传导货币政策的一个主要渠道,中央银行制定货币政策时必须要考虑股票市场。     

我国股市与货币需求的相互影响分析及政策涵义

运用协整、弱外生性和因果关系检验对我国股票市场与货币需求的关系进行的实证研究发现,股市不影响M2的总量但影响其结构;M1对股市不产生直接影响,而M2对股市的直接影响处于有与无的临界状态;M1、M2均通过GDP对股市产生间接影响,但没有形成利率传导机制,我国股市是关于协整向量的弱外生变量.基于以上结论提出了相应的政策建议.     

Stock market uncertainty and economic fundamentals: an entropy-based approach

This study investigates the effects of stock market uncertainty on economic fundamentals, represented by economic activities and systemic risk, in China. To capture the uncertainty in the Chinese stock market precisely, we use the entropy measure through symbolic time-series analysis. The empirical findings reveal strong spillover effects from stock market uncertainty to economic fundamentals. Specifically, an uncertainty shock generates (i) a short-term decline in industrial production, (ii) a rapid drop and rebound in the composite leading indicator, and (iii) an increase in systemic risk. To understand these findings, we suggest and validate the transmission channel through changes in consumption and investment.     

World capital markets and Finnish stock returns

The paper explores issues related to time-varying global equity market integration from a Finnish perspective. Finland is an interesting market since profound economic changes and financial deregulation have taken place since the mid-1980s. Using Finnish firm size ranked portfolios and a conditional four-factor asset pricing model, several restrictions on asset behaviour are examined. It is found that a proxy for changing market integration — lagged foreign equity ownership — has a significant impact on the relative importance of local and global risk factors. Significant differences are found between the pricing of shares that were freely-available to all (unrestricted shares) and domestic investors only (restricted shares). Results also suggest that major capital market reforms profoundly affect the degree of market integration, but local risk factors do not become redundant.     

论证券交易所补充责任制度的创设——以投资者民事权利保护为基点

证券交易所补充责任制度的创设既防止了对证券交易所的过度归责倾向,又保护了投资者的合法权利.目前,我国学术界、实务界和司法界对该制度很少论及.本文对证券交易所补允责任的含义及构成要件、性质、归责原则、效力以及因果关系和举证责任等问题进行论述和探讨,以期完善我国投资者民事权利保护的内容.     

Unusual operating cash flows and stock returns

The current financial reporting of cash flows from operations does not present individual sources of these cash flows, making it difficult for investors to assess a firm’s future performance. I hand-collect individual cash flows from unusual operations and examine their characteristics for predicting future cash flows. The results show that the unusual individual cash flow items contain a significant incremental predictive ability for future cash flows. Additional return tests show that stock prices fail to fully reflect their predictive value, suggesting that the current reporting practice may mislead investor perceptions of a firm’s cash generating ability and investors could benefit from a more explicit presentation of cash flows from operations.     

论我国多层次股票市场转板制度的构建

我国多层次股票市场发展滞后,长期以来没有建立起完整有效的转板制度。为实现我国各层次股票市场之间的有机衔接,需要构建并完善转板制度。要以建立实质性的多层次股票市场为前提,注重满足企业融资需求与维护市场稳定两大目标的协调。要循序渐进推动升板机制的构建。打通升板通道的时机和力度,应当与市场适应性和可承受度相匹配。同时要以退市制度改革为契机,健全降板机制,扩大企业的自主选择空间,增强市场机制的有效性。
