    An Empirical Study on Interest Rate Policy and Banks' Risk Appetite Based on PSTR Model

    Get PDF
    次贷危机爆发以后,国外许多学者致力于危机成因的研究,其中具有代表性的成果是提出了货币政策的风险承担渠道。在对风险承担渠道的研究中,国外许多学者认为:长期宽松的货币政策(低利率)激励金融机构承担了过多的风险,导致了金融系统的脆弱性,从而诱发了金融危机。虽然此次危机对我国影响有限,但是在目前利率市场化的大趋势下,货币政策工具从数量型工具向价格型工具过渡,利率对银行风险偏好的影响势必关系到整个金融系统的稳定性。 在以往的研究中,主要是以广义货币M2作为货币政策的代理变量,在线性框架下研究货币政策对银行风险偏好的影响。本文则直接从利率角度出发,首先阐述了利率政策对银行风险偏好影响的相关理论。其次,由...After the subprime mortgage crisis, many foreign scholars dedicated to study the causes of the crisis, including a representative of the outcome is the proposed risk-taking channel of monetary policy. In the study of risk-taking channels, many foreign scholars believe that: long-term monetary policy (low interest rates) led financial institutions to assume too much risk, leading to the fragility o...学位:应用统计硕士院系专业:经济学院_应用统计硕士学号:1542013115204

    有限元方法是目前结构分析领域应用最为广泛的一种数值方法。自振频率计算作为结构分析中的一个重要内容,可归结为典型的特征值问题,例如:一维波动方程可描述杆结构振动,其特征值为杆结构自振频率;二维波动方程可描述膜结构振动,相应的特征值为膜结构自振频率;三维波动方程可描述声压在空间中的传播,其特征值为声压的振动频率。采用有限元法求解波动方程特征值问题时,质量矩阵的构造方法会直接影响振动频率的计算精度。因而,如何构造可使自振频率有更高收敛阶次及精度的高阶质量矩阵具有重要的研究价值。然而,目前的高阶质量矩阵多限于一维和二维低阶单元,并且二维高阶质量矩阵所得频率计算精度依赖于波的传播方向,不能同时提高各阶频...Finite element method is widely used in structural analysis. Free vibration analysis, an important component of structural analysis, can be classified as typical eigenvalue problems: for example, 1D wave equation can describe 1D rod free vibration and the eigenvalues of 1D wave equation are the rod vibration frequencies; 2D wave equation represents the vibration of membrane, its eigenvalues denote...学位:工学硕士院系专业:建筑与土木工程学院_工程力学学号:2532013115179

    社会主义市场经济的快速发展改变了企业传统的经营管理理念与方法,要求企业对成本管理进行战略适应性变革,始终保持战略创新与维持自身长期的核心竞争力。同时,企业为满足和适应新形势、新常态下的经济环境和市场需求,必须建立以产权为纽带的企业联合组织基本模式——企业集团,构建综合性管理会计体系,实现从战略高度分析研究影响成本的内在因素,挖掘优化整体成本的思路和途径,以增强集团的核心竞争力。目前,国内学者对战略成本管理的研究基本上局限于理论层面的分析,与具体案例相结合分析的研究则比较少;另外,对集团管控的理论研究与其他相关理论进行结合研究的也不多,很少有企业能够把集团管控理论与其他理论有机地结合并运用。 ...Both idea and methods of traditional management have been reformed by recent social economic environment.

    中华民族在长期的历史发展中,受独特的地理环境、物产、思维方式、民俗习惯、价值观念等因素的综合影响,逐渐形成了包罗万象且极具特色的饮食文化,并在多样的世界饮食文化中别具一格。“凿井为饮,耕田为食”,“喝”和“吃”不仅是“饮食”的基本内容,也是维持和保证生命生存和发展的两大重要因素。但人们对“饮食”的理解有时过于片面,将过多的关注力集中于“吃”,对“喝”的重要性则有些忽视。语言作为文化的表达符号和重要内容,以其自身的形式象征、反映或表达一定的文化及文化活动,一方面,汉语中丰富的饮食类词语正是中国饮食文化发达的体现;另一方面,“喝”在吃喝类动词中的重要地位较“吃”缺乏重视,也反映了人们对“喝”之重要...With its unique natural geographical environment,mode of thinking,customs,values and other reasons,China nation have formed their unique cuisine culture in the long process of historical development,and has its unique style in the world.Drinking and eating are two most important contents of cuisine,but drinking is easier to be neglected compared with eating .
