中承式钢管混凝土拱桥地震易损性分析
刘震
公路交通科技 , 2015,
Abstract: 为了研究中承式钢管混凝土拱桥的地震易损性,基于国内工程实际和统计资料对拱桥相关参数进行取值,使用超拉丁法抽样形成桥梁样本,从太平洋地震工程研究中心数据库选取符合我国地质条件的地震记录作为地震动样本,对桥梁和地震样本进行配对;使用数值方法模拟相关动力响应,根据基于变形或内力和积累耗能的双重破坏准则判断其破坏状态。通过概率分析得到桥梁关于峰值加速度(PGA)的易损曲线和关于地震震级、震源距离的易损曲面,为地震风险评估抗震加固提供了理论依据。

Abstract: “奥数”是一项有70多年历史的国际数学赛事,作为高级思维训练体操,对训练青少年思维具有重要作用。但与升学相挂钩的“全民运动”,使奥数学习变味异化[1]。本文作者从一名大学生的视角出发,介绍自己学习“奥数”的心得体会,分析“奥数”跑偏的原因,并指出“奥数”与素质教育的统一。
“Mathematical Olympiad” is an international math competition with 70 years’ history, as a mental training gymnastics, playing an important role in training young people thinking. But the “mass movement” linked with the studies makes the Olympiad learning taste changed[1]. The authors proceed from the perspective of a college student, introduced the experience of learning “Mathematical Olympiad”, analyzed the reasons for deviation in the “Mathematical Olympiad”, and pointed out the necessary of the unite of the “Mathematical Olympiad” and Quality Education.

Abstract: 本文的目的是解释中国的超额货币问题,重点是研究超额货币增量。从中国中央银行基础货币的形成机制出发,通过讨论超额货币的形成过程和产生原因,本文将对于超额货币问题的讨论转化成了对于超额货币增量问题的讨论。为了分析和研究超额货币问题,本文定义了七种变量,来表现超额货币的特征,如货币自膨胀率、货币全膨胀率、货币超名义经济增长率、超额货币增长率、以增量货币数量方程式为基础的货币自膨胀率、存量货币化比率、增量货币化比率等。本文以中国1993~2010年的数据为样本进行实证分析表明,这些变量不仅比传统货币数量论能够更好地解释中国的超额货币现象,而且能够以不同的方式揭示出货币的超额增长率与经济增长率和通货膨胀率之间的关系。
The aim of this paper is to explain the issues of excess money in China. The important point on this paper is to study the issues of excess quantity of money changes. Beginning from the creating mechanism of the basic money issued by the Chinese central bank, by discussing the issuing procedures and producing reasons of excess money, this paper has focused on the discussion of the issues of excess money from the discussion of the issues of excess quantity of money changes. For analyzing and studying the issues of excess money, the paper defines seven variables to show the characteristics of excess money, such as self-expansion rate of money, total expansion rate of money, excess economic growth rate of money, excess growth rate of money, self-expansion rate of money defined in quantity equation of money changes, monetized ratio of money, monetized ratio of money changes. Based on the Chinese data from the period of 1993~2010, the empirical analysis has shown that not only the issues of excess money in China can be explained better than the traditional theory by using these seven variables, but also the correlations between excess growth rate of money and real economic growth rate and inflation rate can be revealed on different ways.

Abstract: 本文从Friedman 的货币数量论出发,通过对Friedman 的货币数量方程式的批判性分析,提出了一个新的增量货币数量方程式模型。通过对该模型中各个变量的逻辑关系进行分析,并采用中国1991~2009 年的年度数据为样本进行实证分析,得出了一些有意义的结论。本文的主要结论是,对于货币M0、M1、M2 等货币类型来说,它们的超额货币增长率与价格指数之间的线性关系具有显著、且很强的负相关性。这一主要结论与Friedman 货币数量论的结论完全相反。
Based on the Friedman quantity theory of money, by critically analyzing the quantity equation of money, this paper has created a new model of quantity equation of money changes. After analyzing the new model’s logical relations between their variables and applying the Chinese annual data samples during 1991~2009 to the empirical analysis, several significant results have been achieved. The major result of this paper is that, for money such as M0, M1, and M2, a stronger substantial negative linear relationship exists between the excess money growth rate and inflation rate. This result is totally different to the result supposed on the Friedman quantity theory of money.
货币供应量作为中国货币政策中介目标的两条路径
Two Paths to the Intermediate Target of Monetary Policy Based on the Money Supply in China
 [PDF]

Finance (FIN) , 2012, DOI: 10.12677/fin.2012.21002
Abstract: 货币供应量是否适合被作为中国货币政策中介目标呢?为了回答这个问题,我们建立了两个理论模型作为两条通向目标解决方案的路径。路径1:在假定货币流通速度为变量而非固定的情况下(阎虎勤、刘震宇,2011)[1],通过应用Friedman(1956)[2]提出的存量收入货币数量方程式,我们建立了一个求解货币供应量增长率预期值的模型。路径2:通过应用阎虎勤、刘震宇(2011)[3]提出的增量收入货币数量方程式,我们建立了另外一个求解货币供应量预期值的模型。通过以中国1994~2010年的数据为样本进行实证分析和敏感性分析证实,虽然通过两条路径我们都可以得到货币供应量增长率的预期值,但是路径2比路径1更显著。
Should the money supply be used as an intermediate target of monetary policy in China? For an- swering this question, we have created two theoretical models as two paths to the target solutions. Path 1: when assuming that the velocity of money is a variable but not a constant (Yan Huqin, Liu Zhenyu, 2011)[1], by using the income quantity equation of money suggested by Friedman (1956)[2], we have created one model to get the expected growth rate of money supply. Path 2: by using the income quantity equation of money changes suggested by Yan Huqin and Liu Zhenyu (2011)[3], we have created the other model to get the ex- pected growth rate of money supply. Based on the Chinese data sample during 1994-2010 the empirical and sensitivity analysis has approved that even though through the two paths we can get the expected growth rate of money supply, the path 2 is more significant than the path 1.
货币增长率、收入流通加速度与通货膨胀—基于中国数据的实证分析

Abstract: 本文以中国1978~2009 年的数据为样本,以Friedman 货币数量论方程式为基础,通过实证分析发现:第一,货币M0 的收入流通速度呈U 型变化,货币M0、M1、M2 的收入流通加速度(收入流通速度的变化率)都不为常数而是变化的。第二,货币M0、M1、M2 的收入流通加速度与货币的增长率之间具有负相关性,但与通货膨胀率之间具有正相关性,这种关系在一定程度上减弱了货币增长率对于通货膨胀的正向刺激作用。第三,货币M0、M1、M2 的收入流通加速度对于通货膨胀的正向影响程度高于货币增长率对于通货膨胀的正向影响程度,这种关系具有长期协整性。第四,从长期来说,货币M0、M1、M2 的增长率和收入流通加速度都是通货膨胀率的单向格兰杰原因。第五,脉冲响应分析表明通货膨胀率对于来自其自身的误差冲击的响应可以被看成是对来自于货币增长率的误差冲击所做出的响应与其对来自于货币的收入流通加速的误差冲击所做出的响应的叠加。
Based on the Friedman quantity theory of money and the empirical analysis by using Chinese data sample during 1978~2009, this paper has found five results: Firstly, the curve of income velocity of M0 is U-shaped, and the income acceleration velocities of M0, M1, and M2 are changeable but not constant. Secondly, the relationships between income acceleration velocities and growth rates of M0, M1, and M2 are negative; however, the relationships between income acceleration velocities of M0, M1, and M2 and inflation rate are positive, these relationships may substantially reduce the impact on inflation from growth rates of M0, M1,and M2. Thirdly, there are co-integrations in the long run among growth rates and income acceleration velocities of M0, M1, and M2 and inflation, whereas that the positive impacts on inflation from income acceleration velocities are stronger than from growth rates of M0, M1, and M2. Fourthly, the growth rates and the acceleration velocities of M0, M1, and M2 in the long run are Granger reasons of inflation. Fifthly, the impulse response analysis has shown that the impulse response of inflation to inflation is the overlap between the impulse response of growth rate of money and the impulse response of acceleration velocity of money.
