经济体制改革引起的生产要素快速流动和分配不均使城乡居民收入的差距日渐加大.以2000~2015年江苏省社会经济数据为样本,采用城乡居民收入比和基尼系数两个指标从时间和空间两个维度对江苏省城乡居民收入差距的变化特征进行了分析.结果表明:随着经济发展水平的上升呈现先拉大后缩小的趋势,整体符合倒U型曲线规律;通过构建回归模型发现多种因素影响城乡收入差距变化;提出缩小江苏省城乡居民收入差距、促进城乡统筹协调发展的对策和建议.  相似文献

改革开放后,我国东部地区产业集聚区吸引了中西部地区劳动力的进入,缩小了地区间的收入差距,同时,人们对环境污染问题的关注度也在增加。为了研究产业聚集、收入差距以及二者的交互作用是如何影响环境的,现今又会对环境产生怎样的影响,采用2011—2020年中国30个省份的面板数据,利用固定效应模型和分位数回归方法,研究产业聚集、收入差距及二者交互作用对环境污染的影响。研究结果表明:产业聚集水平提升有助于降低环境污染,收入差距扩大则增加环境污染;产业聚集和收入差距的交互作用为正,说明收入差距的增加削弱了产业聚集对环境污染的改善效果。因此,应该在注重产业聚集区布局合理性、加大环保教育与宣传力度的同时合理缩小收入差距。  相似文献

怎样缩小东西部高等教育之间的差距是新时代我国高等教育发展的议题,中央和西部地方政府及西部高校十分重视该问题。社会学方法中的“弱干预”是对自组织发育程度高水平社会的小力度干预,“强干预”则是对自组织发育程度低水平社会的大力度干预。迁移到高等教育领域,该概念以缩小东西部高等教育之间差距为标准,认为没有达到缩小两者之间差距目标的干预对策是“弱干预”;达到缩小东西部高等教育之间差距目标的干预对策是“强干预”。从现实的数据分析,从1999年到2019年,东西部高等教育之间的差距在绝对数量上有所缩小,但在反映质的排名上的差距却在加大。从历史的事件分析,中央政府出于战略转移与国防建设需要所实行的东部高等教育向西部的迁移改变了东西部高等教育优质资源的布局。为了实现新时期缩小东西部高等教育之间差距的目标,中央政府要继续加大“强干预”的主导作用,鼓励东部地区优质高校到西部办分校;西部地方政府需要做好“强干预”的辅助工作,制定更加开放、灵活与优质的政策吸引东部地区高等教育资源向西部迁移;西部地方高校需要配合中央与地方政府的“强干预”对策,落实“强干预”的具体工作。  相似文献

陕西省自1994年引进跆拳道运动至今已经十年有余,但各地市的发展情况仍然不容乐观。本文运用文献资料、问卷调查、数据统计法,对陕西省跆拳道运动现状进行研究分析。调查结果显示:各地市水平差距较大,教练员整体素质和专业水平低是影响跆拳道运动发展的主要因素,同时高水平的训练、竞赛体制、经费等问题也是影响陕西省跆拳道运动发展的重要因素。  相似文献

近时,电视及报刊常有运用恩格尔系数测算社会贫富小康的报道。引发笔者深入学习思考。 一、恩格尔系数 德国经济学家、统计学家恩格尔提出“随着居民收入的增加,耗费在食品支出的比例就会减少”。而美国统计学家赖特于1875年据此提出《恩格尔定律》:“食品开支与家庭消费支出总额之比,其数值越小说明生活越富裕;数值越大,其生活水平越低。”其比值称为恩格尔系数,并计算确定恩格尔系数在30%以下为富裕;30—45%为小康;45—60为温饱;60%以上为贫穷。在1974~1984年十年间西方国家国民的恩格尔系数都有降低,日本从28.6%降为23.6%;西德从27.5%降为25%;  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

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.  相似文献

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.  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
