基于区域经济差异的人力资本结构研究——以东、中、西部地区为例

人力资本结构不平衡是区域经济差异的形成原因之一,人力资本结构与区域经济发展之间存在相互作用关系。我国东、中、西部地区人力资本投资结构、人口配置结构和产业分布结构等由于经济发展水平的差异而表现为有限均衡变动。尽管人力资本平均水平逐步提高,但人力资本结构性矛盾依然存在,在此基础上提出了相应的调控对策。     

人力资本积累与经济增长研究综述及启示

从人力资本计量的不同方法角度归纳评述了当前国内外有关人力资本与经济增长关系研究中的重要文献,结论表明:人力资本与经济增长存在正向关系,但不同学者实证研究人力资本产出贡献率的结果存在较大差异,而人力资本计量方法的差异是导致相关研究结论不一致的重要原因.因此,在对人力资本的计量方法进行评价的基础上,从人力资本投入与产出角度建立了更能综合反映人力资本水平的评价指标体系,以期对于后续实证研究人力资本积累与经济增长的关系具有一定的参考价值.     

甘肃省人力资本与经济增长关系的分析

通过建立人力资本评价体系,利用1978-2008年统计数据,运用计量分析方法,对甘肃省人力资本与经济增长的关系进行了分析。结果显示:甘肃省人力资本与经济增长存在的长期均衡关系,对经济增长影响显著,但在短期对经济增长没有明显的作用。对此,提出加大人力资本投资力度,合理匹配人力资本投人与物质资本投入等促进甘肃经济增长的政策建议。     

人力资本转化因素分析

人力资本是经济增长的重要源泉之一已成为不争的事实,但对经济起真正推动作用的并非是劳动者所具有的全部知识、技能、经验等潜在人力资本,而只是其中物化在商品中形成实际人力资本的那部分,两者之间存在着一个转换关系,这种转换的大小受多种因素的影响。本文在引入人力资本转化模型的基础上,详细地阐述了影响人力资本转化的多种因素。     

泛珠三角地区人力资本对经济增长的贡献率测算研究

人力资本对经济增长的作用越来越重要,作为我国区域经济的重要板块,泛珠三角地区的经济增长少不了人力资本要素的贡献。基于人力资本与经济增长的相互影响机制,采用泛珠三角9个省区数据,测算了各省区人力资本对经济增长的贡献率大小。研究发现:泛珠三角地区的人力资本还存在着贡献率不足、结构失调、地区发展失衡等问题。相对而言,广东和福建的人力资本和经济增长的各项指标状态较好,而其他省区则较为落后,地区内差距较大。据此,提出了更具针对性的泛珠三角地区人力资本开发对策。     

新疆的人力资本投资与经济增长

从世界经济增长的事实和趋势来看,经济增长的因素除了劳动力和资本数量之外,还有一个更重要的因素在起着关键性作用,这个因素就是人力资本。人力资本与经济增长有密切关系。从新疆维吾尔自治区过去发展来看,经济增长大量依靠物质资本投资,人力资本投资对新疆经济增长的贡献率较低,新疆的人力资本投资还存在亟待解决的问题。     

四川创新型人力资本与经济增长的实证分析

使用创新型人力资本以受教育程度为计量标准,通过单位根检验、协整分析方法和VAR模型,分析四川创新型人力资本存量与经济增长的关系以及创新型人力资本水平与产出水平的关系。结果表明,虽然四川创新型人力资本存量与经济增长之间存在长期的均衡正向关系(即创新型人力资本每增加1%,产出可增加0.752%),但是创新型人力资本水平对产出水平还不是很明显(即创新型人力资本存量对经济增长的影响还比较低)。最后,提出四川人力资本投资的相关对策建议。     

区域人力资本与经济增长关系的评价研究——以重庆为例

构建了人力资本水平的综合评价指标体系以及人力资本与经济增长关系的评价模型,在此基础上利用主成分分析测算出重庆人力资本的综合水平,运用计量经济方法,论证了重庆人力资本与经济增长之间存在长期的协整关系,从而通过对模型的协整分析揭示了重庆目前人力资本水平与经济增长之间的关系,指出了重庆经济发展中的不足,并据此提出了相应的政策建议.     

空间关联视角下异质性人力资本与经济增长质量

人力资本是改善中国经济下行压力的重要源泉。在描述2005—2017年我国31个省区市经济增长质量和投入要素典型性事实的基础上,分析了全国层面、阶段层面异质性人力资本对经济增长质量的影响。研究发现:相较于2005—2009年,2010—2017年我国经济增长质量较低,异质性人力资本对经济增长质量的作用高于物质资本和就业人数,且存在显著空间关联;从全国层面和分阶段看,异质性人力资本及其空间滞后项对经济增长质量存在显著促进作用,且这一作用高于就业人数、物质资本的作用。这表明,未来中国为发挥经济增长质量的空间溢出效应,应在增加区域异质性人力资本投入的基础上,强化区域间异质性人力资本流动。     

略论人力资本的演进过程

随着人们对人力资本理论研究的不断发展,对人在经济增长过程中地位的认识也在不断升华.但我国理论界对人力资本内涵的理解存在很大分歧,从而导致人力资本理论的延伸产生泛化的倾向.从企业产权制度发展的层面,对人力资本演进过程进行剖析和研究,对于完善人力资本理论无疑是有所裨益的.     

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.     

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.     

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.     

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.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.

橡胶颗粒沥青混合料低温抗裂性试验研究

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.     

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。     

Quantitative trait loci （QTLs） for quality traits related to protein and starch in wheat

Quality traits in wheat （Triticum aestirum L.） were studied by quantitative trait locus （QTL） analysis in a recombinant inbred line （RIL） population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross （ChSh）. Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.     

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.
