本文从临空经济的发展动力出发,探讨郑州航空港临空经济对周边区域经济的带动作用(直接带动和间接带动)。其中,"直接带动"作用主要通过测算郑州航空港临空经济区的"宏观乘数效应",来考察临空经济对区域经济的带动效应;"间接带动"作用主要采用"波士顿矩阵"来衡量郑州航空港不同产业所处的位置和发展特点。然后从"机场因素""腹地资源回报率""港区发展回报率"和"空间结构因素"4个方面构建评价指标体系,对郑州临空经济的发展效率进行评价。通过探讨临空经济与区域经济的互动关系,以寻求对郑州航空港经济发展现状的新理解。 相似文献

机场被喻为国家和地区经济增长的发动机,临空经济作为一种依托机场资源而出现的新型经济形态和高端区域发展模式,在推动区域经济发展中发挥着越来越重要的作用。太原武宿机场是国家4E级机场,中国民用航空第十三个五年发展规划将太原机场定位为区域枢纽机场,因此打造适合太原市发展的临空产业体系,将成为推动太原市乃至山西省经济转型发展的新动力、新引擎。 相似文献

在发达国家和地区,以"自由贸易区"模式推动临港经济的发展是一条值得借鉴的经验。我国20世纪90年代初期开始实行临港"保税区"政策,先后在十几个城市设立了20多个不同类型的保税区,对我国临港经济的发展起到了非常大的促进作用。但在实践中,也存在海关监管制度建设滞后,保税区与港口缺乏一体化联动,空港的管理体制创新落后于海港等问题。为此,建议在我国重点临空经济区域实行"综合保税港区"的政策模式,并以此为契机推动我国临空经济更好、更快地发展。 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

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
