人民币实际有效汇率对中国贸易收支的影响--基于中国-东盟六国的实证研究

基于1994—2012年人民币汇率和中国-东盟六国贸易的年度数据,采用协整方法和Granger因果检验考察了人民币实际有效汇率对中国贸易收支的影响。实证结果表明,中国-东盟六国贸易收支的汇率弹性为-0.46,不满足马歇尔-勒纳条件;人民币实际有效汇率不是中国-东盟六国贸易收支的Granger原因,现阶段人民币汇率调整并不会对中国-东盟六国的贸易收支产生显著影响,相反,国内外实际收入尤其是国外实际收入的上升对双方贸易收支的影响较大。     

马歇尔—勒纳条件的再推广

从贸易收支的汇率弹性入手，分析了有多种进出口商品的情况下，本币贬值对贸易收支的影响，并通过对传统模型的精细化，推导出在此情况下本币贬值能改善贸易收支的条件。     

日本大灾后如何重建

由于这次是地震、海啸、核泄露三重灾难的叠加，生命和财产的损失都非常惨重，因此灾后重建的物资和资金需求极为庞大，很可能对日本的主权债务和贸易收支状况以及全球金融市场与大宗商品供求产生重要的影响。     

“一带一路”背景下中国与新加坡服务贸易的博弈发展

通过对新加坡与中国在服务贸易领域的经济数据比较、发展过程分析,阐述了新加坡与中国之间服务贸易的差异,对比得出中新两国服务业发展的特点,重点介绍了新加坡在服务业发展的经验,同时分析了在"一带一路"背景下中新两国未来在服务贸易中的合作前景,以博弈理论为基础,分析中、新两国之间服务贸易发展存在的冲突和矛盾,预测新加坡未来与中国在服务业等领域合作发展的趋势。     

人民币实际有效汇率的测算及其对于贸易收支的影响

实际有效汇率是研究开放经济体的核心变量之一.采用了1995-2006年间的季度数据,测算了支出法衡量的人民币实际有效汇率.并且度量了实际有效汇率的变化对于贸易收支的影响,探讨了改善贸易收支的途径.     

供求弹性与外汇收支平衡

本文介绍了西方进出口供求弹性对外汇收支调节作用的学说，并试图用这一学说对我国近年来汇率变化对外汇收支影响加以说明。本文的结论是：在出口中“薄利”并不一定“多销”，只有在充分考虑出口商品供求弹性的情况下作出的销售决策才能做到多出口，多创汇，有助于外汇收支的改善。当然，外汇收支调节的成功，最终要依赖于国内经济健康、迅速发展，仅仅期望通过货币贬值来改善外汇收支，将会对国内物价起到一定程度的推动作用。     

中国对东南亚国家油气产业链出口潜力研究——基于面板引力模型

利用面板引力模型估计中国对东南亚国家油气产业链贸易潜力并估算未来出口增长空间。研究发现:中国和东南亚国家经济规模均正向影响中国油气产业链出口贸易;贸易总量上新加坡和马来西亚贸易潜力较大,新加坡、印度尼西亚和菲律宾油气产业链贸易潜力较大;未来5年内,中国对东南亚国家油气产业链出口潜力明显受约束,应更多关注贸易和投资并举的方式。     

我国旅游服务贸易逆差形成机制及对策研究

参照国际旅游收支统计方法,界定我国出入境旅游消费范围,对2009—2014年我国国际旅游贸易收支数据进行回溯、修正,发现自2012年始,我国旅游服务贸易出现逆差,之后逆差额升速较快。为遏制逆差额进一步扩大,厘清我国旅游贸易逆差形成机制,提出扭转逆差格局的应对之策迫在眉睫。     

浅议我国利率传导存在的问题及对策

以凯恩斯的利率传导理论为基础,从货币需求的利率弹性、投资需求的利率弹性和投资乘数3个因素来探讨目前我国利率传导存在的问题及原因,并提出了完善我国利率传导的对策和建议.

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.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

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.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
