股指期货对资产管理行业的影响——基于新兴古典经济学视角

本文从新兴古典经济学的视角探讨股指期货对中国资产管理行业的影响,以及股指期货对中国资本市场的结构性影响.从理论视角来看,基金业规模经济的实现途径是通过不断提高基金业的专业分工水平,增强基金业的生产力而实现.这种专业分工分为横向、纵向两种扩张.公募基金的投资管理能力横向扩张,指的是从传统的股票和债券市场延伸到金融衍生工具市场、实业投资等领域,投资能力纵向的分解,是将基金的收益分解为Alpha和Beta两部分.随着股指期货的推出,国内公募基金的投资管理沿横向、纵向的扩张,成为现实、具体的可能.投资策略的演变推动投资部门的变化,使投资策略经历再构造过程,形成Alpha和Beta的分离,并促进Beta产品、Alpha产品的深化发展.     

中国公司债券交易量与价格波动的关系

使用中国沪深证券交易所的公司债数据,检验了债券交易量与价格波动的线性关系和非线性尾部相关性,分析了债券流动性水平对量价关系的影响,研究了债券量价关系的时变特征。结果表明:中国公司债市场中债券交易量与价格波动之间存在显著的线性关系;债券流动性水平对量价关系有显著影响,债券流动性水平越高(低),则量价关系越弱(强);债券交易量与价格波动存在非对称的下尾相关性;债券量价关系具有时变性,市场低风险时期量价关系较弱,市场高风险时期量价关系较强。

当前经济形势与未来发展趋势的几点判断

本文通过对欧债危机以及美国经济、全球通胀、增长动力转换等方面的分析,指出金融危机对中国的影响仍在深化,经济下行和通胀的压力依然存在.作者同时认为,支撑我国长期增长的因素没有消失,后发优势依然存在,估计未来10年中国经济仍有潜力维持年均8％以上的高增长.应对复杂经济形势的基本思路是,长远要防控由高增长转向中速增长出现大幅下滑的战略转型的风险,当前要预防通胀,优化结构,鼓励改革创新,消除经济扭曲,营造更加公平、公正、自由且充满活力的发展环境.

民营中小科技企业技术源生成机理研究

技术源是企业技术创新的核心问题之一,技术来源路径和作用过程,构成了企业技术源生成机理。民营中小科技企业的创建模式、经营方式和市场竞争环境,使其技术源的生成仍以实用主义为原则,以外源型的获取方式为主流,以灵活的激励机制为动力。这种技术源生成机理的前景取决它的活力维护与进阶提升。     

国际货币体系改革——金融危机后的思考

美国次贷危机引发的全球金融危机,使现行国际货币体系—牙买加体系的缺陷进一步暴露出来:美元本位制放纵了美国的过度消费,国际资本流动缺乏监管以及不稳定的汇率体系加剧了危机蔓延。虽然对国际货币体系的改革面临美元霸权、改革成本高等方面的阻碍,但改革现行的IMF以及扩展国际救助范围,加强金融监管力度已然成为改革方向。     

Informed trading and liquidity in the Shanghai Stock Exchange

Dufour and Engle (J. Finance (2000) 2467) find evidence of increased presence of informed traders when the NYSE markets are most active. No such evidence, however, can be found by Manganelli (J. Financial Markets (2005) 377) for the infrequently traded stocks. This article investigates the issue of informed trading and its relation to liquidity in Shanghai Stock Exchange. Consistent with the hypothesis that information-based trade exists for all stocks, our findings suggest an increased presence of informed trading in both liquid and illiquid stocks when markets are active. Moreover, for the actively traded stocks, our results support the price formation model of Foster and Viswanathan (Rev. Financial Studies (1990) 593) that activities of informed traders deter uninformed investors from trading, thereby reducing market liquidity.     

‘Doing-good’ and ‘doing-well’ in Chinese publicly listed firms

Recently, the presumed benefits of corporate social responsibility have become an important issue, especially for China where institutional settings are quite different from other parts of the world. Using an internationally accepted benchmark (OECD's Principles of Corporate Governance, OECD, 2004), this study constructs a corporate social responsibility (CSR) index to measure the quality of the corporate social responsibility practices of the 100 major Chinese listed firms during 2004–2007. This enables us to evaluate the progress of the corporate social responsibility practices of Chinese firms. The results show that Chinese companies have been making progress in their corporate social responsibility practices. The findings also show that market rewards Chinese firms for improving their corporate governance practices which implies ‘doing-good’ leads to ‘doing-well’ in the equity market in China. We also find that overseas-listed and more profitable Chinese firms have better improvement in CSR practice. This study has policy implications in pushing for further CSR initiatives in other emerging markets.
