中国东部经济增长的驱动因素及其差异性分析

运用扩展的Cobb—Douglas生产函数,分析了区域经济增长的驱动因素,并基于东部11省市的面板数据,采用变系数的SUR统计方法进行研究。结果显示：①能源消费对经济增长的作用显著,但存在区域差异;②资本投入对经济增长存在滞后影响,经济增长不仅受资本投入总量的影响也受到投入结构的影响;③以能源强度表征的技术进步是经济增长的主导因素,认为能源技术进步不仅有利于减少能源消耗,而且还可以促进经济的增长,能源密集型向资本密集型和技术密集型的转变,是东部地区可持续发展的必然趋势。     

科技进步对经济发展促进作用的分析与研究

随着经济的发展和社会的进步,科学技术在经济增长中的作用越来越突出,成为推动生产力和经济发展最直接的动力。从技术与经济的结合上,分析了科技进步在推动经济发展、经济结构的变更和经济增长方式转变中的促进作用。     

以“科技是第一生产力”为导向 实现两个根本性转变

国民经济的发展现状决定了中国经济必须要实现两个根本性转变；科学技术的性质和地位决定了实现两个转变必须以科技作为导向。科学技术的“第一生产力”本性表现为它的客观品性以及它在生产力中的地位和作用，其导向作用表现为科学技术通过增殖价值剩余、改变有机构成、推进波动周期、提高生产函数及投入产出率来引导经济的增长内涵和集约程度而使增长方式得以转变，又通过优化资源配置、改变市场结构、创造生产需求、推动流通环节而引导市场体系的发育和成长而使经济体制得以转变。同时，产业结构、企业制度的变革和产品战略的选择也将作为中介而使科学技术、经济增长、市场体制三位一体的联动发展得以强化。     

浅析经济稳定与经济增长、经济发展

有的学者认为,经济增长是指社会财富即社会总产品量的增加,它一般用实际的GNP和人均GNP的增长率来表示。经济发展当然包括经济增长,但还包括结构的变化,诸如投入结构的变化、产出结构的变化、产品构成的变化和质量的改进、居民生活水平的提高和分配状况的改善等,以及经济、政治和文化条件等的变化,甚至观念、习俗等社会诸方面的变革。可以看出,这时主要是就经济增长和经济发展包含内容的不同而区分。其中,经济增长     

运用高新技术,改造提升传统产业

<正> 人类社会进入二十世纪以来,生产力结构发生了重大变化,科学技术成为推动经济发展和社会进步的决定性因素和主导力量。江泽民总书记早在1995年的全国科学技术大会上就指出:"创新是一个民族进步的灵魂,是国家兴旺发达的不竭动力"。我们目前正处在世纪之交的重要历史时期,科学技术突飞猛进,知识经济初见端倪。科技成果转化为现实生产力的速度日益加快,科技成果产业化成为当代经济增长和社会发展的鲜明措施。朱镕基总     

基于全要素生产率的服务业增长质量评价研究——以浙江省为例

建立了服务业增长质量评价指标体系,然后以浙江省为例,估算了服务业的外溢效应和全要素生产率(TFP),得到相应结论;运用因子分析和计量分析方法,进一步论证了服务业增长质量的影响因素。研究结果表明:发展、结构、效益与环境中的诸多因素对服务业增长质量提高具有正向作用;服务业结构还不够优化;简单劳动的投入不利于服务业技术进步,人力资本对服务业增长质量改善具有积极作用。     

一种多部门经济增长因素分析方法

提出了一种分部门情况下对经济增长的因素分析方法，可以估计劳动、资本的投入增长及其配置结构的改变、劳动者素质变化和新设备新技术应用对经济增长的贡献，并通过实际数据估计了这些因素对美国1990—2000年经济增长的贡献。     

国际贸易与经济增长:一个扩展模型

根据国际贸易和经济增长理论的最新发展，促进一国经济增长的主要因素有劳动、资本积累、土地（自然资源）、技术进步、社会制度环境和对外贸易。将传统生产函数的投入要素扩充，可以根据需要推导出多种要素增长促进经济增长的回归方程式。由于促进经济增长的诸要素之间存在复杂的相关性，多因素回归分析难以充分体现贸易对经济增长的促进作用，本文将采用贸易增长促进经济增长的单因素回归分析和贸易加速增长促进经济加速增长的回归分析，回归分析结果不仅证实了贸易增长能促进经济增长，而且发现改革开放后，制度创新和技术进步在经济增长中也发挥了重要的作用。     

深圳技术进步在经济发展中的作用

一.技术进步在经济发展中的作用研究的现实意义 深圳特区的经济发展史,是一部艰苦创业的历史,同时也是依靠技术进步创业的历史。以科技进步促进生产的发展。已成为深圳特区今后经济腾飞的重要手段,“科学技术是第一生产力”这一论断,已被人们逐渐理解。对经济增长与技术进步作用的研究,西方经济学家总是把它们联系在一起。技术进步测算方法的研究已有数十年的历史,并已形成多种流派。其理论体系和计算方法,各有各的见解。无可否认,科学技术愈是发达,对经济增长的影响愈是巨大。由此,科技进步因素对经济增长影响的测算理     

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.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

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
