    随着人们对安全生产、安全操作意识的不断提高,如何高效、安全地实现工业炸药的生产成为现阶段民爆企业需要解决的首要问题,以往的工艺、设备落后,自动化水平低的工业炸药生产线所带来的人员多、效率低、危险性高、消耗大的生产状况已经不能满足使用需求,将面临被淘汰的尴尬境地。国防科工委下发的《全国民用爆破器材业发展“十一五”计划纲要》明确提出:“将重点发展连续化、自动化的工业炸药生产线,限制并逐步淘汰以间断式及手工操作为主要生产方式的工业炸药生产线,使其向着系列化、多品种、高性能、高安全性、高可靠性、低污染方向发展,以满足各种爆破作业的需要。”因此,开展基于高效、安全的乳化炸药生产线设备的应用研究,将对生产...As people on safe production, operation safety consciousness, how to improve the efficient and safe production of industrial explosive as industrial enterprise needs to solve the problem of the past, process, equipment, low level of automation of industrial explosive production line, the low efficiency and high risk, the consumption of large production status, cannot satisfy the demand has been us...学位:工程硕士院系专业:物理与机电工程学院机电工程系_机械工程学号:X200718200

    一方面,经过多年的研究和探索,我国在内部控制领域已经取得了许多研究成果,比如我国在公司治理和内部控制相互关系这一论题上发表了很多篇论文,但是这些文章均只是公司治理结构和内部控制相互关系的原理性阐述,后续没有进行案例剖析、实证研究;另一方面,中国上市公司内部控制强制执行阶段已经启动,加深投资者、管理层、监管方、债权人、公众等对内部控制的认识显得日益重要,而理解公司治理与内部控制之间的关系可以加深对内部控制的认识:本文在这两个背景下展开研究。 内部控制和公司治理关系国内出现了三种截然不同的观点:包含观、对接观、交叉观。本文试图在三种观点的基础上,将公司治理分为内部公司治理和外部公司治理,又将内部...In one hand, after so many years, we have developed lots of researching results about internal control including the relationship between corporate governance and internal control, however, those researches regarding relationship between corporate governance and internal control are concentrated in basic principles without case study or empirical research; in the other hand, our public companies a...学位:管理学硕士院系专业:管理学院会计系_会计学学号:1752009115100

    郁达夫是一位对政治非常敏感的作家,他对工农的看法和态度至今看起来仍然很有见地。但学术界对他的工农观没有给与足够的重视,而工农观对郁达夫的创作和生活又具有非常重要的影响。所以,本文希望对郁达夫的工农观进行客观而深入的探索,以求对其思想有更加全面的认识和了解。本文主要是从以下三章进行探讨: 第一章主要论述了工农观的演变。主要分为四点:中国传统社会下的工农观、马克思、恩格斯的工农观;蔡元培与“劳工神圣”;早期共产党人的工农观。 第二章是全文的主体部分。该部分在对工农观有一定的认识的基础上,着重介绍郁达夫的工农观及其有关工农观的创作。本章主要分为三节:郁达夫的工农观及其特点、郁达夫工农观的两大关键...Yu Dafu is a very sensitive writer of political, his attitude of workers and peasants still looks very thoughtful.

    Free Cash Flow and Over-investment:An Empirical Research Based on Agency Cost Theory

    Get PDF
    Jensen于1986年基于管理者行为视角进行分析,提出了“自由现金流假说”。他认为由于存在代理冲突,管理者会利用企业的自由现金流进行过度投资。我国上市公司“内部人控制”与大股东控制十分严重,导致过度投资行为普遍存在,重复建设现象非常严重,造成了资源浪费与投资效率低下。过度投资行为降低了经营绩效与企业价值,并最终损害投资者利益,不利于经济的良性发展。因此,研究我国上市公司自由现金流引发的过度投资行为具有重要的理论价值与现实意义。 本文借鉴Richardson于2006年构建的预期合理投资模型,以2004-2008年沪深两市的上市公司为样本,研究了我国上市公司自由现金流引发的过度投资问题及其影...Based on the analysis of managerial behavior, Jensen raised the "Free Cash Flow Hypothesis" in 1986.
