汇率波动对资本市场间溢出效应的影响

随着中国外汇管理制度改革日益深化,不断增强的人民币汇率波动对资本市场的影响越来越显著.基于改进的VAR模型构建了我国资本市场间的溢出效应指数,实证分析了汇率波动对资本市场溢出效应的冲击影响,进一步对比分析了不同的汇率波动区间对资本市场溢出效应冲击影响之间的差异.研究结果表明,不同波动率水平样本下人民币对美元汇率波动对资本市场溢出效应的影响具有非对称性,低波动率样本下汇率波动对资本溢出效应的冲击影响最显著;实证结果也证实了汇率的剧烈波动容易导致资本市场间溢出效应具有双边性.     

汇率与股价波动:基于中国与日本高频数据的ARCH检验

立足次贷危机所产生的结构性影响,采用ARCH模型对人民币汇率、上证指数、日经225指数的高频数据进行实证研究发现:次贷危机发生前,汇率与股指存在ARCH效应,且均有不对称信息的冲击,波动存在持续性的影响;次贷危机发生后,汇率与股价都不存在ARCH效应,系统性风险和非系统性风险暴露出来使得汇率对股市的波动影响降低,从而促使投资者风险得到有效对冲。     

跨境贸易人民币结算资金来源与管理探讨

跨境贸易人民币结算为外贸企业提供了便利,有利于规避汇率风险,降低交易成本.我国于2009年推出了跨境贸易人民币结算试点,至2010年2月已经取得一定的进展.然而,人民币结算资金来源的问题制约了跨境贸易人民币结算的进一步发展.为此,应进一步完善配套措施,增加人民币结算资金来源渠道,强化对人民币跨境流动的监管并加强产品创新.

推动跨境贸易人民币结算在外贸企业中运用的对策研究

跨境贸易人民币结算业务自推出以来,随着相关监管政策和制度的不断完善,得到了长足的发展。参与跨境贸易人民币结算业务的外贸企业从中有效的规避了汇率风险,节约了结算的成本。然而,要更好地推广该业务在外贸企业中的应用,须加强我国外贸企业自身实力、提升人民币国际影响力,简化该业务的手续。     

基于PLS模型的通货膨胀影响因素分析

利用偏最小二乘分析方法分析了房价、信贷、货币供应量、汇率和资本价格波动对通货膨胀的影响,结果表明：房价上涨、汇率升值、信贷扩张、货币供应量增加以及资本价格上涨都会形成通胀压力,其中房价上涨与汇率升值对通货膨胀的影响最为显著。据此,建议大力支持保障性住房建设,收缩货币供应量和信贷规模,引导人民币汇率合理升值,加大监管资本市场,完善各项法规制度。     

外汇储备够不够?

正2015年8月11日人民币汇率中间价报价机制市场化改革以来,人民币汇率出现了较大的波动且形成较为明确的贬值预期,市场预期的变化使得2015年下半年资本流出较为明显,美元资产成为了市场以至居民争相配置的资产,资本流出与贬值预期相互强化,并带来了人民币资产的重估效应。     

试论我国产业资本投资金融业的动机

当产业资本发展到一定阶段时,由于对资本需求的不断扩大,就会开始不断向金融资本渗透;而金融资本发展到一定阶段时,也必须要寻找产业资本的支持,以此作为金融产业发展的物质基础.于是,产业资本与金融资本相结合,必将是中国市场经济发展的必然趋势.     

关联于资产价格波动的货币政策非对称性检验——基于修正NK-SVAR模型的实证分析

资产价格波动通过多种途径影响宏观总产出,进而间接反映在货币调控的效应测度上.基于此,本文针对新凯恩斯模型进行了修正,在货币政策非对称效应的SVAR模型检验中导入了资产价格变化和汇率波动的影响.实证结果表明,紧缩货币政策较扩张性政策具有更强的产出冲击,但其效应显著关联于资产价格变化,这就要求资产价格变化必须纳入到未来相机抉择的货币政策体系中.     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。     

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.
