政府补贴提升了企业创新效率吗? ——来自战略性新兴产业上市公司的经验数据

选取中国战略性新兴产业上市公司数据,从行业层面实证检验了政府补贴对企业创新效率的影响.研究表明:政府补贴有助于企业创新效率的提升,政府补贴对不同产权性质、不同生命周期阶段企业创新效率的影响存在差异.政府补贴对国有企业创新效率的促进作用大于非国有企业.政府补贴对成熟期企业创新效率的促进作用大于成长期企业,对衰退期企业创新效率则表现为不显著的抑制作用.深化和拓展了政府补贴与创新效率关系的研究,可为政府部门制定补贴政策,提升补贴效率以及战略性新兴产业企业利用政府补贴实现创新效率提升提供借鉴和参考.

充分发挥中小企业在创新中的重要作用——基于中关村创新示范区的调研

中小企业既具有创新活力优势,也存在资源不足劣势,实际创新绩效依赖于创新环境。中关村利用先行先试的政策优势,在示范区聚集创新要素,根据企业规模特点促进企业发展,按照产业发展规律促进新兴产业集群发展,帮助中小企业发挥优势、克服劣势,形成以中小企业为主的创新型产业集群。中关村创新示范区的统计数据表明:中小企业与大型企业相比,在创新投入上力量基本相当,而在创新产出上贡献较高,在创新强度和创新效率上表现更佳,中小企业已经成为中关村区域创新的重要力量和新兴产业发展的重要源头。     

基于DEA模型的农业企业创新绩效评价与分析——以河南省鄢陵花木产业集群为例

农业企业创新绩效已成为了解农业企业自身创新发展状态和指导农业企业提高创新资源利用效率的有效依据.基于创新系统理论,运用数据包络分析法(DEA),对鄢陵县花木产业集群中27家花木企业的创新发展状况进行绩效评价分析.结果表明,该集群农业企业的创新综合效率偏低,且企业之间存在显著差异,纯技术效率对企业的创新综合效率影响显著.结合分析的结果,提出如下相关发展建议:企业自身要加大科研投入和相关人才培训力度;深化企业产学研合作程度;政府机构要制定相关政策法规对集群企业的创新进行积极引导和鼓励;提高企业的经营管理水平,加强管理创新,促进规模效率提升.

研发补贴和税收优惠对高技术产业创新效率的影响研究

应用随机前沿方法(SFA)测算中国高技术产业17个细分行业在2000—2014年间的创新效率。基于效率的角度实证研究了政府研发补贴和税收优惠政策对中国高技术产业技术创新的影响。主要研究结论为:税收优惠政策能显著地促进中国高技术产业创新效率的提高。但是,政府研发补贴与高技术产业创新效率之间呈现负向关系。进一步研究发现,对大企业来说,应更多地使用税收优惠政策。对小企业来说,研发补贴政策的效果更显著。此外,国有产权比重越高的产业,研发补贴和税收优惠政策对创新效率的提升作用都不明显。     

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
