政府控制、公司治理与企业避税
Government Control, Corporate Governance and Corporate Tax Avoidance
 [PDF]

Abstract:
在我国的制度背景下,国有经济占相当大的比重。政府主导的市场经济改革决定了我国特有的经济“双轨制”,最终决定了上市公司受不同实际控制人的影响。随着现代企业制度的不断发展,两权分离导致公司治理问题日益突显。本文以2007~2013年中国A股上市公司为研究样本,首先实证分析了政府控制、公司治理结构对企业避税的影响,然后根据实际控制人性质将上市公司细分为中央政府、省级政府、市级政府、县级政府及非政府控制五种类型,研究不同政府层级控制对避税的影响作用,并对比分析了不同实际控制人下公司治理对避税行为的影响效应。研究发现:相比非政府控制的企业,政府控制的企业避税行为更加保守,尤其是中央政府和省级政府控制的企业。监事会有效的监管可以抑制企业避税行为,股权集中度对避税是正向作用。本文的分析为深入探讨政府控制、公司治理与企业避税的关系提供新视角。
Under the background of Chinese special system, state-owned economy accounts for a large proportion. The market economy reform led by the government determines our unique dual-track economy system, and it finally determines that listed companies are subject to dif-ferent actual controllers. With the ever-developed modern enterprise system, the separation of ownership and management right leads to corporate governance issue increasingly prominent. Using Chinese listed companies during 2007-2013, this paper firstly studies the influence of government control, corporate governance on tax avoidance behavior and then divides the listed companies into five kinds according to their controlling characteristic: cen-tral-government controlling, province- government controlling, city-government controlling, county-government controlling and non- government controlling and empirically analyses the impact on tax avoidance of different government-levels controlling. The results suggest that compared to non-government controlled companies, the tax avoidance behavior of government controlled companies are less aggressive, especially central-government and prov-ince-government controlled companies. Effective regulation of board of supervisors can reduce corporate tax avoidance and ownership concentration has a positive effect on tax avoidance. This paper provides new perspectives for further analyzing the relationship between govern-ment control, corporate governance and tax avoidance.

Abstract:
本文以电气工程及其自动化专业为背景,分析了电气类专业实践创新能力实际培养情况,以专业导师工作制、帮扶计划、学科竞赛和校企合作平台,结合人才培养目标和专业特点,构建了集毕业设计、课程设计、综合性设计性实验项目和创新性实验项目的实践教学体系框架,以及以工程意识和工程素养形成的“多位一体”的实践创新能力培养模式。经实践教学结果表明,以培养学生实践创新能力为主线的实践教学改革探索,取得了较好的教学效果,也为其他地方高校在培养应用型人才方面提供了新的思路。
This paper analyzes the practical training of the practical innovation ability of electrical specialty based on the background of electrical engineering and automation specialty. In this paper, the professional mentor work system, helping plan, subject competition and school enterprise coop-eration as a platform, combined with the objective of talent training and professional characteristics, the practical teaching system framework is constructed, which is a practical teaching system of graduation design, curriculum design, integrated design experimental project and innovative experimental project, as well as the engineering consciousness and the engineering accomplishment form “a number of one body” practical innovation ability training mode. The practice teaching results show that in order to cultivate students practical innovation ability as the main line of the practice, the teaching reform achieved good teaching results, and it also provides a new way of thinking for other local colleges and universities to cultivate applied talents.

现代政治代表的历史类型与体系结构

中外法学 , 2014,
Abstract: 在公法上,命令——服从这种经验性的支配现象背后隐含着特定的代表结构。从绝对君主制、立宪君主制、民主共和制三种政体形式中,可以抽取出代表的三种历史类型,它们分别是超越代表、二元代表和内在代表。在三种历史类型的背后,代表所涉及的问题逻辑显示出一定的相似性,此问题逻辑构成了代表的体系结构。在人民主权的语境下,代表的体系结构由解决授权问题的形式代表和解决公意实现问题的实质代表两个维度构成。从展示和接近公意的方式来看,实质代表又可以区分出静态代表、决断代表、竞争代表和商谈代表四个维度。代表的体系结构所涉及的各维度,可以作为分析一国宪法的具体代表结构时的参照标准。

Abstract: 提出一种基于区域显著性融合规则的非降采样Contourlet变换的红外与可见光图像融合方法.首先,对来自同一场景图像的红外与可见光图像的??分量进行非降采样Contourlet变换;然后,依照区域匹配度量和显著性度量规则进行融合,而融合图像通过非降采样Contourlet反变换即可得到.最后,针对此方法进行大量实验,并将其融合结果与基于小波变换及拉普拉斯金子塔变换的融合结果进行比较,同时分析它们在不同噪声条件下的性能指标.
煤矿井下定向钻进用刮刀型PDC钻头的研制与应用

煤炭工程 , 2015, DOI: 10.11799/ce201509043
Abstract: 在煤矿定向钻进过程中,由于钻孔深度可达千米以上,钻进地层也从单纯煤层逐步转移到复杂多变的岩层。在井下地层条件比较复杂、岩性种类较多的长距离钻孔钻进过程中,普通PDC钻头经常会发生磨损、冲蚀等现象,且寿命和时效不能满足使用要求。针对这一问题,研制了一种刮刀型PDC钻头,钻头采用刮刀型浅内锥结构,可以排布更多切削齿,具有良好的排粉效果,并可根据地层情况进行调整钻头切削角与侧转角。通过现场试验证明,在岩层定向钻进中使用效果良好。
