金字塔控制、管理层持股与公司全要素生产率——来自中国制造业国有上市公司的经验证据     

李凯  邹怿 《预测》2010,29(2):13-20

研究了金字塔控制结构对管理层持股与公司全要素生产率关系的影响.使用中国制造业国有上市公司的实证数据估计相应的面板数据模型,结果显示:现金流权越高,终极控制股东监督管理层的动机越强,管理层持股对公司全要素生产率的正向影响越大;终极控制权与现金流权的分离程度越小,终极控制股东越倾向获取现金流权收益,对管理层的监督也越强,增大了管理层持股对公司全要素生产率的正向影响.研究证明在金字塔控制结构下,现金流权与两权分离程度具有显著的治理效应,能改变终极控制股东的监督动机,从而影响管理层持股的激励作用.研究表明,管理层股权激励的推行必须与严格的监管相结合才能在最大程度上发挥其正向激励效应,降低其负向影响.  相似文献   

Religion in Chinese education: from denial to cooperation†     

Hirotaka Nanbu 《British Journal of Religious Education》2008,30(3):223-234

In China, from the founding of the People's Republic of China to the beginning of the Cultural Revolution, it was thought that religion would disappear with the development of society and the freedom not to believe in religion was stressed. During the Cultural Revolution religion became the object of oppression. However, from the end of the Cultural Revolution in the late 1970s to date, the long‐term existence of religion came to be accepted. Searching for cooperation between socialism and religion, ways in which religion could effectively contribute to modernisation began to be put forward. In comparison with the previous situation, the current period is marked by a much more tolerant policy. If one looks at religion in education, first, at the level of legal codes, the separation of public education and religion is extolled based on the rule of separation of religion and state. And, it is clearly forbidden to engage in activities that use religion to interfere with educational activities. This applies to ethnic minorities as well. Second, be this as it may, religion is touched upon at all levels of education. For example, at the level of high school education, the distribution of the three major world religions is explained and many other religions are introduced. Moreover, the culture and customs of some religions are introduced. In higher education, in universities and graduate schools, the Religious Studies major has been created for the training of those in charge of regulating religions as well as scholars. Third, several of the religions recognised by the Chinese government have developed institutions to train personnel. Furthermore, some of these institutions are working in cooperation with institutions of higher education to offer programmes of study. In this way, especially following the end of the Cultural Revolution, cooperation between socialism and religion was sought. And, coexistence with ethnic minority groups, which believe in a number of different religions, was considered. And yet, within school education, the treatment of religion is strictly limited. Only education that aims at a basic knowledge of religion is conducted. There are significant national differences in the relationship between education and religion. It would be fruitful for China to reconsider this relationship, taking account of developments in other countries, in the present situation where the Chinese government has a more tolerant policy towards religion.  相似文献

汉语有标复句层次关系的自动分析一直是中文信息处理的热点和难点,本文在前人基础之上,引入关联词的离析度这一概念,从一种新的视角来对原先一些复句层次自动划分的方法进行一种补充和完善,从而为人们更好的实现复句层次的自动识别打下基础。  相似文献   

Re及Ma对边界层的影响分析     

王继明 《中国科技信息》2011,(19):66-66

本文分析了跨音速流中Ma及Re对边界层的影响,结论为Ma的增加使得激波强度增加,流向逆压梯度增加,边界层厚度增加较快,容易分离;Re的增加有两个效应：一是使得转捩提前,二是使得边界层变薄。R e增加使得激波后机翼表面压力降低,升力损失减小。跨音速范围内,Re对边界层与外流的干扰十分显著。  相似文献   

钾细菌的分离及对Cu^2＋的耐受性实验研究     

李甲亮  杜文琪  张文秀  张鑫  王雪  李飞星 《滨州师专学报》2014,(3):68-71

利用分离培养基从草坪、芦苇地、公园以及菜园土壤中分离到一株高效钾细菌菌株,经纯化后,研究了钾细菌对铜的耐受阈值,并筛选了提高钾细菌Cu^2＋耐受阈的钝化剂。结果表明,钾细菌最高能耐受Cu^2＋的浓度为50mg/L。投加钝化剂粉煤灰和石灰后,钾细菌对Cu^2＋的耐受阈提高到80mg/L,粉煤灰对重金属铜的钝化性能优于石灰。  相似文献   

量刑阶段的证明责任与证明标准问题研究--从新常见罪量刑意见展开     

赵恒 《内江师范学院学报》2014,(11):50-55

量刑与定罪有着不同的司法功能,在量刑阶段,寻求设计与之相适应的证明责任、证明标准以及证据规则等制度内容,是我国定罪量刑程序分离改革过程中的重要组成部分。在深化司法改革大背景下,结合新刑事诉讼法增加“排除合理怀疑”的证明基本要求、扩宽当事人参与法庭调查与辩论范围、建立量刑建议制度等内容,可以得出：在量刑阶段建立相对独立的证明标准、证明责任等制度,既有其必要性,也有其可行性。  相似文献
