中国消费函数模型的实证研究及讨论

采用计量经济学线性回归的计量方法,以凯恩斯的绝对收入假说、莫迪利安尼生命周期假说等为理论依据,分析了家庭平均可支配收入、当期收入、持久收入等因素对我国城市居民、农村居民消费的影响.结果表明,中国城市居民的当期消费主要由其当期收入决定,而农村居民的当期消费由它的当期收入和个人资产决定.     

带收入分配影响因素的中国城镇居民消费分析

文章采用标准差变异系数来度量中国城镇居民的收入分配差距，通过标准差变异系数与城镇居民平均消费倾向之间的散点图，确定两者间的函数关系，并在此基础上，改造弗里德曼的持久收入假说消费函数模型，构建带收入分配影响因素的消费函数模型。     

陕西省农村居民消费结构的实证分析

利用统计软件SPSS分析了陕西省农村居民的消费结构；研究了陕西省农村居民消费结构升级与变化趋势；提出了提升陕西省农村居民生活消费需求的对策，首先要增加农村居民的收入，其次应引导合理消费，改变农村居民的消费观念，还应在农村开展信用消费，向农民发放消费贷款。     

我国农村居民消费问题实证分析

用经济计量学的方法，以相对收入假说为经济理论基础，利用回归方法估计出我国农村居民的边际消费倾向为0.883，即农民收入每增加一个单位，消费将增加0.883个单位。然后采用了Panel Data对引起我国东部、中部、西部农村居民消费差异的地区因素进行计算，得到结果：东部地区在总支出、食品、衣着、及居住、医疗保险、文教娱乐消费方面比中部、西部有较强的购买动机，在交通通讯消费方面西部地区有较强的购买动机。     

数字普惠金融对农村居民消费的影响——基于直接效应和间接效应模型分析

基于2011—2019年全国31个省（自治区、直辖市）的面板数据，采用动态面板和中介效应模型，实证分析数字金融对农村居民消费的影响。结果表明：数字金融显著促进了农村居民消费，其中3个分指数对农村居民消费均产生正向影响，覆盖广度、使用深度的促进效应略强于数字化程度；数字普惠金融有助于增加农村居民收入，间接影响村民消费支出，其中介效应占比为10.54%。进一步分析发现，数字普惠金融的发展有利于农村居民消费结构的转型升级。     

收入来源对城乡居民消费影响差异的实证研究

根据消费者的"心里账户"认知差异,将居民收入分为主动性收入和转移性收入,分析了城乡居民不同的消费行为和两种不同收入对城乡居民消费的影响.研究结果表明:城乡居民改变消费策略时倾向于调整自己的转移性收入;城镇居民的主动性收入边际消费倾向高于农村居民的主动性边际消费倾向,且波动更剧烈,但农村居民转移性收入的边际消费倾向高于城镇居民的转移性收入边际消费倾向;城镇居民主动性收入在消费中的贡献份额相对稳定,而农村居民主动性收入的贡献在2001年后迅速下降,转移性收入在消费中的贡献度逐步提升.因此,为了提高消费需求,政府的民生财政支出政策应该侧重于增加农村居民转移性收入、提高城镇居民主动性收入,同时应该建立城乡统筹的社会保障制度.     

从生命周期/持久收入假说看我国的消费情况

运用"生命周期/持久收入假说"分析我国消费现状,可以看出改革开放之后,居民的收入和消费水平有了很大提高,消费结构也不断提升。如果在理论分析的基础上,注意这种理论对我国消费现状分析的适应性,并用过度敏感性假说和预防性储蓄理论进行补充说明,可以得出:在消费群体分类的前提下,结合各层次消费的实际,有针对性地提出刺激消费、扩大内需的宏观经济对策,是适合我国目前国情的。     

我国农村居民消费水平的实证分析——基于全国31个地区2000-2005年数据的Panel Data模型

针对现阶段中国出现了消费需求不足的现象,国内学者从结构性矛盾、信用梗阻、收入分配不均等角度提出了多种解释,也有学者从城乡消费结构的角度进行了研究,其中大量的学者都赞同农村需求不足是导致我国有效需求不足的根本症结：由于我国农村居民所占比重较大,因此,我国农村消费市场难以启动,难以与城市消费市场同步增长,影响了我国国民经济的发展.     

似第三产业:解决农村居民收入问题的新视角

农村居民收入问题越来越受到社会各界的关注,且其已经对中国经济的健康发展构成威胁。故本文引入似第三产业的概念,通过改善农产品生产、消费体制,满足社会各层次消费者的消费需求。通过对似第三产业经济理论分析,证明其在促进农村居民收入的提高和中国国内经济的稳定有重要作用。     

广西农村居民体育消费结构与特征

分析广西农村居民体育消费结构现状，探讨体育消费结构存在的问题.研究发现，广西农村居民体育消费结构构成比存在显著性差异，具有明显的年龄、教育、收入等特征，呈现出以“实物型”体育消费为主，“娱乐型”“参与型”体育消费为辅，以及体育消费结构分配不合理现象.提出优化广西农村居民体育消费结构的优化建议：完善体育基础设施建设营造浓厚的体育消费氛围，巩固农村经济发展引导农村居民进行体育消费，强化体育消费质量监管提升农村居民体育消费满意度，创新体育产品供给促进农村居民消费结构合理化，弘扬民族体育文化推进农村居民体育消费特色化.     

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
