本文归纳了流动性刻画维度和度量指标,选取不同规模和价位股票的高频数据作样本,吸收Amivest流动性比率计算原理,设定价格对交易量变动的敏感性为流动性度量指标,分析股票日内交易特征和流动性影响因素。结果发现:日内模式价格变动呈仰卧“F”形,交易量呈仰卧“E”形,而非传统的“L”或“U”型;日内交易模式、股票规模和股票价位均影响着股票流动性;日内模式异动时间内,股票流动性差;大规模股票流动性强;高价股流动性差。 相似文献

1.基于消费行为的跨期消费平滑模型 对经常账户的跨期分析方法源自消费和储蓄的持久收入理论.在一个小的与世界资本市场接近的开放经济的研境里,持久收入理论暗示着暂时的冲击(这里定义为对当前资源的很大的冲击而不是一生资源的冲击)可以导致国民储蓄和经常账户非常大的波动. 相似文献

文章通过对我国银行业数据的实证分析,发现银行的资产配置行为与流动性冲击有显著的相关关系。市场流动性和融资流动性的提高能够改善银行的流动性,同时也激励了银行持有更多的风险资产。流动性宽松时期,不断提升的市场流动性和融资流动性,使银行风险资产过度膨胀,为危机埋下隐患。 相似文献

本文从微观角度研究了股票市场流动性的影响因素。从公司业绩水平、资产规模、股票的市场风险、股价等方面分别进行了单因素相关性分析。结果发现:影响流动性的主要因素有每股收益、总资产、股票的贝塔系数和股价,而净资产收益率对流动性的影响不大,并且净资产收益率和每股收益之间存在偏相关关系。 相似文献

流动性过剩对证券市场的冲击效应分析——基于海外经验与中国实践的实证研究 总被引:1,自引:0,他引:1
本文认为,货币差额法应是衡量宏观经济流动性过剩的首选指标,货币供应量超过了实体经济增长所需要的货币量就是流动性过剩,并构建了相关统计指标.结合可比的海外经验,当前我国股指虽已高位回落,但流动性的收缩会对股市产生滞后一年或两年的影响.为了防止流动性过剩变化对今后股市产生剧烈变动,甚至引发暴跌,管理层应有预见性地把握流动性紧缩的力度和节奏;投资者也应密切关注有关管理部门,尤其是央行对流动性过剩状况的判断和采取的紧缩措施的力度和节奏. 相似文献

VaR模型作为风险度量和管理的工具,已经被金融机构和监管当局广泛接受。但是,由于它是一定置信度和持有期内衡量资产头寸所能遭受的最大损失,它并没有考虑到是否能够真的以所计算出的可能的最差价格将所持有的头寸变现。在实践中,两个具有相同的VaR值,但流动性高低不同的投资组合,其变现的最差价格是不同的。因而,很多学者对传统的VaR模型提出了质疑,并认为把流动性风险的度量加入到目前已非常成熟的风险管理体系VaR模型中,是金融风险管理领域的一个严峻挑战和紧随的任务。 相似文献

Abstract. It has long been recognized that banks' simultaneous provision of monitoring and liquidity services is advantageous but leaves them susceptible to liquidity shocks that may culminate in a system failure. Because a system failure is costly, this provides a rationale for adopting arrangements, including a lender of last resort and deposit insurance (DI), to insure banks against liquidity shocks. These arrangements have proven themselves very successful, but they have also been the source of problems. Researchers have identified some of the main sources of these problems and have suggested ways to improve the design of these arrangements, but there are still many issues that remain unaddressed. This paper reviews the literature on the two arrangements that most countries have adopted to insure banks against liquidity shocks, a lender of last resort and DI, and compares the design of these arrangements across countries. The paper ends with a brief summary of the key lessons learned about the design of these arrangements and the issues related to them that remain unaddressed. 相似文献

货币供给内生性与外生性问题是一个重要的理论和现实问题,正确判断一个经济体的货币供给内外生性对于认识货币供给运行机制、制定正确的货币政策以及提高货币政策的有效性都具有重要意义。本文以现金漏损率为切入点,深入分析其对货币乘数、进而对货币供给量的影响,并得出我国货币供给内生性增强的结论。最后,在该结论的指导下,为我国选择正确的货币政策以及如何提高货币政策的有效性提出了若干建议。 相似文献

We used data from the Chinese stock market to quantify the amount of time for the market to converge to efficiency. Order imbalance may predict returns when there is no designated market maker. In spite of availability of the direction of trade information in the Chinese stock market, it takes longer for information regarding order imbalance to be incorporated into stock prices in China than in the USA. With information on past returns and order imbalance, it takes between 15 and 30 min to converge to efficiency in the Chinese stock market. The process of converging to efficiency depends highly on liquidity. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

股票价格与价值的测度及特性分析--基于流动性的新解释 总被引:4,自引:0,他引:4
流动性对股票价格与价值的作用与关系,传统的研究主要是从市场流动性角度展开分析的,这种研究的局限性主要在于市场流动性的研究只是从市场这个单一的角度来对股票价格进行测度,没有从流动性变化的最大部分即资产流动性的第一个飞跃——从股票标的资产到股票流动性的飞越来对股票价格与价值的作用进行分析。基于此,本文从流动性的研究现状出发,重新定义了资产流动性对股票价格与价值形成的作用,在对流动性价值进行测度的基础上,揭示了股票价格与价值的形成机制及相互作用特性,得出了流动性的价值测度、股票价格的形成过程、价格与价值的差异特性。 相似文献

This research paper has explored the image of China portrayed in the New York Times from 1949 through 1988. The study has shown that the image of China has changed in accordance with the changes in the U.S. foreign policy toward China over the past forty years. The changes were discussed in the historical context of Sino-U.S. relations. In addition, this paper has explored some methodological issues relating to Q-analysis. This methodology, different from Q-sort technique, is proven particularly powerful in this study for describing semantical structures in a cluster of news stories. 相似文献

Drawing on recent theoretical tenets regarding cross‐border regions, this article analyzes China's state spatial policies that aim to transform Yunnan from a peripheral frontier into an economic bridgehead. The purposes of the present study are threefold: to contextualize the formation of Yunnan as China's frontier; to examine why Yunnan has been strategically selected as a bridgehead to promote China's transnational economies; and to explore the central–provincial alliance as an innovative institutional arrangement and look at how this alliance can convert Yunnan into a space of exception or new state space of development. This study finds that in order to convert regional assets into real competitiveness, the Chinese state (national, provincial and local) emphasizes transnational cooperation, endeavors to maximize Yunnan's place‐specific locational advantages and promotes the differentiation of regional developmental trajectories across China's national territory. The article contributes to studies of institutional arrangements for cross‐border cooperation in a non‐Western context and sheds light on China's regional development policies in its hinterland. 相似文献

The purpose of this paper is to briefly trace the evolution of DEA from the initial publication by Charnes et al. (1978b) to the current state of the art (SOA). The state of development of DEA is characterized at four points in time to provide a perspective in both directions—past and future. An evolution map is provided which illustrates DEA growth during the 17-year period, the timing of the major events, and the interconnections and influences between topics. An extensive DEA bibliography is provided. 相似文献

分析了1991-2008年间我国物流成本各要素的发展阶段及其成因,阐述了物流成本结构管理的意义,利用SAS、SPSS等软件对物流成本中的运输成本、库存成本和管理费用占总成本的比例拟合时间序列模型,并根据模型对未来几年我国物流成本各要素比例进行了预测,最后将预测结果进行横向和纵向比较,可以看出未来几年我国物流成本结构没有太大变化,各项物流成本并没有得到很好的控制和节约,这也说明了我国物流业的发展主要是数量和规模的发展,在质量方面还有很大的改善空间。 相似文献
