Study of Relationship Between Liquidities of Bond and Stock Market——Evidences from Shanghai Stock Exchange

金融市场之间相关性的研究是金融学的基础课题。一般来说，对金融市场相关性的研究主要集中在收益率和波动率上，而市场间流动性的相关性一直没有得到深入研究。本文深入研究了上交所股票市场与债券市场流动性的动态相关性，并给出一定的政策建议。 为了检验两个市场流动性的相互关系，本文采用如下方法：首先，在模型中加入虚拟变量，拟合结构突变的VAR（或VECM）模型，研究两个市场流动性的相互关系；其次，用DCC模型拟合残差，研究两个市场的动态相关性；最后，进一步从理论上分析债券市场对股票市场具有流动性传导效应的原因，并用实证加以验证。 实证结果表明，两个市场的流动性分别在2006年1月和2006年6月发生了结...Relationships between different financial markets are fundamental issues of the modern financial research. In general, researchers in this field mainly focused on the relationships between returns or volatilities while the relationship between liquidity proxies of different financial markets are not paid much attention to. In this thesis, I endeavored to find out the relationship between the liqui...学位：经济学硕士院系专业：经济学院金融系_金融工程学号：1562007115148

英语隐喻在汉英文化中的异同

随着改革开放的持续推进,我国与其他国家的交流与合作日益密切,由此掀起了英语学习的热潮,并逐渐发展成为一门核心课程。同时在很长的一段时间内,高中英语教师将教学重点放在了学生语言技巧与能力的培养上,却忽视了其语言运用能力的提升,尤其是跨文化交际能力,更是成为高中英语教学的薄弱环节。在这一背景下,向学生渗透英语的背景文化知识便成了高中英语教师的重要任务,需要教师赋予英语教学以文化精神,运用隐喻这一语言现象与人类认知模式,有效提升学生的文化意识与语言运用能力。</jats:p

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
