我国机构投资者行为与证券市场稳定研究

近来，有关部门提出了超常规培育机构投资者的证券市场监管政策，认为机构投资者能稳定证券市场，提高证券市场运行效率。但是，机构投资者并不必然能稳定证券市场，市场的稳定还需要一定的制度环境。     

投资者利益保护与新兴市场证券发行管制

本文构建了一个模型,说明在一个非有效程度比较高的证券市场中,公司可以通过发行新股融资侵占外部公众投资者的利益。此时,证券发行的门坎管制和规模限制对保护投资者利益是必要和有效的;如果事后的投资者利益的法律保护等监管制度的有效性弱, 证券发行管制就更有必要,以此来限制经营能力较差的公司为NPV<0的项目融资。对融资和投资分离的研究还表明,限制上市公司融资规模可以减少管理层基于自我利益的过度融资和低效投资。随着投资者保护的法律制度完善和执行有效,信息披露规范,加上机构投资者力量壮大,市场评价能力增强,可以放松证券发行事前的门坎限制和融资规模限制,逐步实现证券发行市场化。     

本地偏好、投资者情绪与股票收益率:来自网络论坛的经验证据

本文以投资者在东方财富网股吧针对创业板上市公司发表的90多万条帖子为研究对象,通过IP地址识别,构建本地关注指标;并利用计算机文本挖掘技术,提取网络发帖所体现的情绪倾向,构建投资者情绪指标。实证结果显示,本地关注对股票收益率的影响取决于投资者情绪,当投资者持积极情绪时,本地关注对股票收益率有显著的正向影响;当投资者持消极情绪时,该影响显著为负。在积极情绪和消极情绪下本地关注对股票交易量都有显著正向影响,但积极情绪下的影响程度比消极情绪下更大。此外,本地关注与投资者情绪的交叉效应在上市公司样本数量较多的北京、广东、江苏、上海、浙江这五个区域都存在,并与整体样本的特征基本一致,但在样本数量较少的其他区域并不完全一致。     

The Effect of Word-of-Mouth Communication on Stock Holdings and Trades: Empirical Evidence From an Emerging Market

The purpose of this study is to investigate the relationship between investors’ satisfaction and intention and word-of-mouth communication. This study contributes to the ongoing debate on the relationship between investor behavior and word-of-mouth communication. Many studies are related to investors’ participation and individual investors’ asset allocation decisions that are instigated by their social community via word-of-mouth communication whereas this study directly investigates the relationship between investment satisfaction and intention and word-of-mouth communication. We emphasize how many factors are considered when making satisfactory investment decisions. Our results confirm the strong relationship between the satisfaction and intention of investors and word-of-mouth communication. This finding may be useful to regulators, investors and managers who seek to establish effective rules for stock holdings and trade.     

证券虚假陈述民事诉讼行政前置条件的取舍

保护投资者权益是推进资本市场基础制度改革的重点方向.长期以来,证券虚假陈述民事诉讼前置条件给投资者寻求司法救济设置了巨大的阻碍.为了更好地保护投资者利益和顺应改革方向,最高人民法院在处理涉及该前置条件的案件时,审判思路也从注重前置条件的程序性功能转变为强调其证据功能.取消行政处罚作为硬性前置条件是证券民事诉讼发展的方向...     

Modeling how institutional investors allocate business to brokers

A model of how institutional investors evaluate and allocate business to brokers shows a complex pattern of influences. The broker's ability to execute transactions at appropriate prices is basic, but this combines with research and sales force performance to build a relationship that affects over-time allocation of business. It is difficult to separate relationship and selling performance, and relationship is subject to considerable decay. Research ability has a weak effect on business allocated on the basis of trading, while trading ability does affect business allocated on the basis of research.     

境外战略投资者持股比例对中国商业银行绩效影响研究

本文选取28家国内银行1995-2008年的面板数据,研究引入境外战略投资者持股比例对我国银行盈利能力、资产质量、稳定性、资产配置能力、创新能力、公司治理等经营层面的影响。研究结果显示,境外战略投资者的持股比例提高有助于提升银行贷款质量和改善公司治理,但境外战略投资者持股比例对银行盈利能力、稳定性、资产配置能力、创新能力影响并不显著。境外战略投资者持股比例对不良贷款率和存贷比的影响呈U型,该比例在达到一定水平(拐点)后会增加银行的贷款投放,而在增加银行贷款投放的同时不良贷款率也会增加。     

'More is not necessarily better': the relationship between the quantity and quality of training efforts

International comparisons indicate that, on average, Belgian companies spend less on training than their French, German and Dutch counterparts. Encouraging companies to commit to training has consequently been an important policy goal over the last few years. One notable aspect of the policy to encourage training efforts by companies is that the effort is always represented in terms of the resources invested (input), not in terms of the learning achieved (output) or the quality of training programmes (throughput). Government policy is aimed at increasing the level of investment in company training. One of the questions we wish to investigate is whether this input-oriented approach to the training issue is actually effective. Whether companies will succeed in raising human capital to ever-increasing levels may depend not only (and maybe not even chiefly) on the extent of financial investment in training. The investment level does not necessarily determine the quality of the training processes developed by companies. Therefore, this paper focuses on the following research questions: (1) to what extent do companies monitor the systematic development of sufficiently effective training processes? In other words, is qualitative under-investment an issue, alongside financial under-investment? (2) Is the level of financial investment in company training correlated to the quality of training processes? The empirical data confirm that a kind of 'qualitative' under-investment can be reported and that the relationship between the level of investment in training and the quality of the training programmes is weak.     

论国有商业银行引进境外战略投资者的必要性

针对国有商业银行在股份制改造过程中引进境外战略投资者,国内存在截然相反的两种观点。实践表明,引进境外战略投资者有利于银行的持续改革与制度创新,有利于在资本市场成功筹资与上市,对于降低改革成本、尽快改善公司治理水平具有重要的现实意义。
