    以最近的金融危机为背景,本文研究了不同金融结构下银行风险因子对系统性风险的影响,对金融体系系统性风险与金融结构的相关文献进行了补充。本文使用结构活动性指数作为金融结构的主要衡量指标,基于28个国家从2007年至2009年的面板数据与固定效应模型进行研究发现,银行风险因子对金融体系系统性风险的影响取决于金融体系的结构:金融结构越偏向市场,银行规模对金融体系系统性风险的贡献越小;反之,金融结构越偏向银行,银行规模对金融体系系统性风险的影响越大。此外,在银行偏向型的金融结构中,银行资本量与金融体系系统性风险负相关;但在市场偏向型的金融结构中,银行资本量与金融体系系统性风险正相关。使用结构规模指数进行...This research contributes to the literature on systemic risk and financial structure by analyzing the effects of bank risk factors on systemic risk conditional on banks’ underlying financial system structure to find bank factors that specifically determine risk in each financial system during the recent global financial crisis.

    2008金融危机的爆发令各国的金融监管机构意识到金融体系中系统性风险的重要性,也使得系统性风险方面的研究成为学者们关注的热点。要有效加强对系统性风险的监管,必须以能够有效识别并科学测度系统性风险为前提。边际期望损失(MES,MarginalExpectedShortfall)是由Acharyaetal.(2011)提出的一种金融系统性风险测度的新方法。MES是指在市场收益率出现大幅下跌时,某单个金融机构的系统性风险贡献,该指标可用于确定公司在金融危机中将面临的资本损失。相应的长期指标为长期边际期望损失(LRMES),即未来一段较长时间内,市场股票价格指数下跌大于某一阈值时单个金融机构的系统性风...The outbreak of the financial crisis makes the financial regulators of many countries aware of the importance of systemic risk in the financial system, which also makes researchers interested in systemic risk. In order to effectively strengthen the regulation of systemic risk, we must be able to effectively identify and scientifically measure systemic risk as a prerequisite.Marginal Expected Short...学位:理学硕士院系专业:经济学院_统计学学号:1542014115200

    2008年金融危机以来,各国逐渐加强对金融宏观领域的监管,致力于研究系统性风险度量问题。学者们通过构造跨机构和跨国家的系统性风险模型,研究其中的联动效应以及风险溢出问题。在这一背景下,研究我国金融体系的系统性风险刻不容缓。本文致力于研究我国上市商业银行风险度量及风险溢出问题,之所以重点研究上市商业银行,其原因在于商业银行是我国金融机构的主体,研究银行间的系统性风险对我国金融风险的监管以及推行宏观审慎的评估体系政策有着极为重要的意义。 本文选取已上市的14家银行,分为国有大型商业银行,全国性股份制商业银行和区域性城市商业银行三类,利用或有权益分析法(CCA)计算出各个银行的市场价值、资产波动率...Since the financial crisis in 2008, many countries have gradually strengthened the supervision of financial in macro areas.

    本文在Fama-French(1992)[1]三因子模型的理论框架下,运用Fama-MacBeth(1973)[2]两步回归法研究行业板块轮动对股票超额收益率的影响。我们发现,中国股票市场上存在着明显的行业板块轮动现象,强势板块与弱势板块总在不停的交替转换。我们构建了衡量板块轮动的变量,发现在时间序列检验中,板块轮动风险溢价是构成股票超额收益的重要组成部分,在横截面模型中,板块轮动风险因子总是能够带来正向显著的风险因子溢价。相对于三因子模型,在时间序列检验中,市场风险因子溢价、与市值相关的风险因子溢价、与账面市值比相关的风险因子溢价仍然是构成股票超额收益的重要组成部分,但是在横截面模型中,市场...This paper mainly focuses on the section rotation effects on excess stock returns. The basic framework of our research comes from three-factor model of Fama-French(1992)[1], and we mainly use the two-step regression method of Fama-MacBeth(1973)[2] in our tests. We find that section rotation is a very common phenomenon in china’s stock market. During fifteen years of our sample, every industry is a...学位:应用统计硕士院系专业:王亚南经济研究院_应用统计硕士学号:2772014115279

    The Influence of Corporate Reputation on Firm Risk——Based on American Listed Firms

    企业声誉是企业资产中极其重要的一部分,是一种极具竞争优势的资源,具有建立长期性和毁灭迅速性的特征。在如今企业逐渐步入声誉竞争的阶段的情形下,企业声誉已经成为学者关注的焦点,故研究企业声誉对企业存在什么样的影响极具意义。传统文献中,大部分学者都是研究企业声誉对企业财务绩效表现的影响关系,较少去研究企业声誉对企业风险的影响,尤其是研究以不同衡量方式表示的企业声誉对不同类型企业风险的影响,这也正是本文所要研究的内容和创新之一。首先,本文对企业风险和企业声誉的理论进行介绍,选取合适的企业声誉和企业风险的衡量方法,并提出企业声誉对企业系统性风险、非系统性风险、整体性风险的不同影响关系的假设。然后,本文以...Corporate reputation is an extremely important part of corporate assets and a highly competitive resource, has characteristics of the imbalance between the long time it takes to build it up and destruct rapidly.

    众所周知,随着我国投资基金业规模的不断扩大,股票型证券投资基金已经成为了我国机构投资者乃至资本市场上最重要的组成部分。同时,一个较严峻且急迫的问题摆在了理论界和实务界面前。作为资本市场“主力军”之一的股票型证券投资基金,是否具备非系统性风险补偿能力?本文的研究就是围绕这个问题展开。 本文从基金非系统性风险与非系统性风险补偿的视角出发,通过考察基金非系统性风险的绝对补偿、横向和纵向的相对补偿三个方面,得出结论:第一,在2002至2008年的样本期间,我国股票基金平均而言具备非系统性风险的绝对补偿;第二,我国股票型基金具备非系统性风险的横向和纵向相对补偿;第三,由于申购赎回等因素的影响,我国开放...As the size of Chinese investment fund industry continues to expand, the equity funds have already become the most important institutional investors in the capital market of our country.

    股指期货作为一种套期保值的工具,通常被投资者用来规避现货市场中的系统性风险。然而,2015年下半年的股灾,关于股指期货的一系列管控措施陆续实施,股指期货却被认为是做空股市,造成大盘持续杀跌的导火索。全面客观地阐述股指期货在我国金融市场的发展情况,剖析比较股指期货的套期保值效果,对于促进我国资本市场的平稳健康发展有着重要意义。 本文以最大程度发挥股指期货的规避风险的功能为前提,运用不同的套期保值比率估计模型对目前在我国上市交易的股指期货进行实证分析和比较。分别选取沪深300指数期货(IF)、上证50指数期货(IH)以及中证500指数期货(IC)作为期货头寸,选择具有代表性的股价指数和ETF作为...As one of the hedging tools, stock index futures are used by investors to avoid systematic risk in spot market.

    近年来,金融市场波动相关性已成为衡量金融风险的一种方法,为风险管理提供了重要依据。为了研究我国金融市场波动溢出的整体水平,机构间的相互影响程度以及在不同市场环境下哪些金融机构占据主导作用,本文就金融机构间的波动溢出效应进行了研究。 本文首先利用Anderson等(2005)提出的非参方法利用高频数据计算金融机构的已实现波动率,接着基于Diebold和Yilmaz(2012)提出的溢出指数来度量金融机构之间的波动溢出水平。溢出指数的计算基础为向量自回归模型中的广义方差分解(GeneralizedForecastErrorVarianceDecomposition)。通过计算,我们不仅能够度量所...In recent years, the correlation of financial market volatility has become a way to measure financial risk, which provides an important basis for risk management.
