基于2003—2016年29个省份的面板数据,首先测度了各省份资本扭曲程度,并运用GMM动态面板模型,实证检验了资本扭曲对地区对外直接投资的影响。研究发现;一是中国存在资本扭曲现象,且不同区域差异显著;二是区域对外直接投资规模与区域资本扭曲正相关,从东部、中部和西部区域来看,发现东部省份资本扭曲对对外直接投资的影响更为显著,而中部和西部地区的影响并不明显。  相似文献

从传统DEA模型出发,考虑环境污染产出,基于2005-2010年中国省际面板数据,引入不同的交叉评价模型对中国各省份的能源效率进行了研究.研究结果表明,中国能源效率整体水平偏低,各省份能源效率存在显著差异,大体呈现出东部省份能源效率高,西部省份能源效率低的格局.此外,“十一五”规划期间我国能源效率大体呈上升趋势,但东西部地区能源效率差距有扩大的趋势.  相似文献

新古典经济增长模型预言,资本将从发达地区流向欠发达地区,而我国改革开放以来省际间资本流动却主要是由西部地区流向较发达的东部地区。本文基于新经济地理的自由资本模型,对我国省际间资本流动的机制进行了分析。认为随着经济发展和经济体制改革的深入,生产资料和消费品跨省交易的成本的不断降低,金融体制的改革和金融机构的发展,促进了资金的在各个领域之间的融通,也促进了省际之间资本的流动,此外,政府对经济干预的程度的下降,也是资本从欠发达地区流向发达地区的重要原因。  相似文献

基于13省25县抽样调查数据, 建立生计资本的测量指标体系, 分析农户生计资本的特征, 并采用有序多分类Logistic回归模型, 探究农户生计资本对生活满意度的影响。结果表明: 1) 金融、人力、社会和物质资本是当前我国农户生计资本的主要组成部分, 自然资本较低, 但依然具有不可替代的保障作用; 2) 农户生计资本具有一定的空间异质性, 东部地区农户的金融、人力、社会和物质资本高于中部和西部地区, 而西部地区农户的自然资本高于中部和东部地区; 3) 农户各类生计资本的增加不一定都会提高农户生活满意度, 物质、金融或社会资本的增加有利于提高农户生活满意度, 而人力资本对农户生活满意度具有负向影响的可能性; 4) 不同地区, 各类生计资本对农户生活满意度的影响程度或影响方向各不相同, 应因地制宜地分析影响农户生活满意度的生计资本类型, 从而有效地提高农户生活满意度。  相似文献

从我国产业结构演变与就业结构演替的偏离度分析发现,西部地区三次产业产值结构与三产业就业结构均比东部地区的偏差要大,显示了较强的不平衡性,这也为西部地区借鉴东部地区先进经验进行产业结构、就业结构调整提供了启示。同时,对东西部内部典型省份的分析发现,东部内部省份的产业结构与就业结构结构偏离度变动趋势与各省具体经济情况密切相关,各省市有一定的差异,说明东部内部各省市经济活跃程度不同。而西部内部各省市产业结构与就业结构结构偏离度变动趋势则显现出相似的特征。  相似文献

为了进一步研究中国各省区之间高技术产业创新效率的差异及其变动趋势,该文以中国各省区2002—2011的高技术产业创新效率数据为基础,应用收敛模型进行了检验。结果表明:虽然全国总体及三大地区创新效率存在着条件收敛,但东部和西部地区并不存在显著的绝对收敛趋势;全国总体及中部的条件收敛因素为科技劳动力资本,东部地区为高技术资本累积,而西部地区则为科技劳动力资本和高技术资本累积,政府资助不是任何地区促进技术效率显著收敛的条件因素。研究结果有利于中国各省区有针对性地建立适合自身发展的政策体系以缩小地区之间发展差异。  相似文献

从路径依赖方面,利用空间计量模型对2002年~2007年中国28个省的创新产出进行研究,运用Stata软件计算结果,得出主要研究结论:东部地区创新系统不存在路径依赖,中西部存在路径依赖性.但中部地区有弱化原有路径的趋势,而西部地区有强化原有路径的趋势.  相似文献

产业梯度转移滞缓原因及西部对策研究   总被引:4,自引:0,他引:4  
产业梯度转移是实现地区经济雁阵发展的条件和途径,对西部地区的资本形成、就业促进、结构调整、制度创新和经济增长具有更为重要的意义。然而,东部发达地区在历经20余年的发展与繁荣之后,其边际产业却并没有像人们所预期的那样,大规模地转移到西部地区,其原因,一是因为东部企业跨区投资的动力不足,二是因为西部地区吸引资本西进、承接产业转移的能力有限。西部地区应依据自身区域特点,制订相关政策,积极吸引资本西进,促进产业转移。  相似文献

采用中国省级层面1997~2009年面板数据实证研究了社会资本和制度因素对研发资本投入产出绩效的影响。结果发现,社会资本的认知维度和结构维度对技术创新的产出影响是不同的,我国专利产出的增加主要依靠本国的研发投入和制度的完备程度,技术市场交易额更多地依赖于社会资本的积累和产权的制度化。  相似文献

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.  相似文献

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.  相似文献

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。  相似文献

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.  相似文献

In the 19th century the society was controlled by men, and women were just appendants of them, they had not any rights and freedom. But Jane was an exception, she showed some characteristics of early feminist. Jane showed her characteristics of feminism in three aspects: rebellion, equality, and independence. These characteristics were helpful to her success, and feminism is the only way out for women of that time.  相似文献

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-  相似文献

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-  相似文献

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  相似文献

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  相似文献

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  相似文献
