新世纪我国城镇居民消费特征变化分析

进入21世纪以来,我国社会主义市场经济体制逐渐完善的同时,城镇居民消费结构也发生了较大的变迁,我国城镇居民消费结构实现了优化、升级。本文运用扩展线性支出系统模型(ELES)对我国2000年和2005年城镇居民边际消费倾向和需求收入弹性进行实证研究,得出我国城镇居民已经结束了满足吃、穿着为主的生存型消费需求阶段,逐步向发展型和享受型阶段过渡的消费特征。

二元结构下城乡居民消费需求的对比分析

基于城乡二元经济结构背景,通过对比分析城镇居民和乡村居民消费需求的过去、现在及未来发展趋势情况发现:现阶段城镇居民的消费需求进入到了一个贫乏期,目前农村居民消费总额虽小,但相对于城镇居民而言未来消费需求高涨,在推动我国经济增长上有很大潜力。因此,应该从多方面进一步挖掘农村居民的消费潜力。     

城镇居民的消费结构分析——以重庆市为例

选取2004—2014年重庆市城镇居民的消费数据,分析城镇居民的消费情况和变动趋势,然后借助扩展的线性支出系统模型(ELES模型),对2014年按照收入5等份分组的城镇居民消费支出数据进行统计研究,对城镇居民的基本需求支出、消费倾向和消费弹性进行数量分析,揭示重庆市城镇居民的消费特征和趋势.食品和居住的基本需求大,消费倾向高;教育文娱的基本需求支出位于前列;交通通讯的边际消费倾向跃居第3,收入弹性大于1,未来增长势头较好;食品价格对其他各类消费品需求的影响最大;交通通讯的自价格弹性较大;随着收入的增加,呈现多样化的消费方式.最后在此基础上提出相应的对策.     

增加河南省城镇居民家庭财产性收入的对策分析

长期以来我国国内消费需求严重不足,极大地制约了国民经济的可持续发展.扩大消费的前提是增加收入,而财产性收入则是居民收入新的增长点.以河南省为例,从微观、宏观以及制度改革完善的角度探讨增加城镇居民家庭财产性收入的渠道途径,对于扩大后危机时代城镇居民消费需求有重要意义.     

收入分配对我国城镇居民消费结构影响的实证分析

改革开放以来,我国城镇居民收入的决定机制发生了根本性变化,居民间的收入差距不断扩大,而收入差距的扩大在一定程度上抑制了城市居民消费的提高,阻碍了城市居民消费结构的进一步升级,进而影响消费需求的增长。目前国内市场需求严重阻碍国民经济运行,制约经济的增长速度。而城镇居民消费结构直接反映了消费者的消费水平、消费特点和消费发展的趋势,并在一定程度上决定了各类消费的变动规律,为此利用Panel Data模型深入分析了城镇居民收入差距对消费结构的影响,并从分配角度探讨解决国内需求不足的办法。

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     

An affordable accurate evaluation of the binding conformations predicted by molecular docking studies in bio-system

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of
