Study on Controlling Shareholder's Behavior Change and Minority Shareholder’s Interest Protection——take listed companys’ownership structure change as the research perspective

中国证券市场经历从股权分置到股权全流通这一制度变革后，整个市场的生态环境和交易环境将发生深刻变化，作为现代公司金融研究的核心问题——控股股东与中小股东之间的利益冲突问题在新环境下必然表现出新的特点。在这一背景下，本文以上市公司股权结构变化为视角，研究后股权分置时代控股股东侵占中小股东利益行为的变化，并在此基础上研究全流通环境下保护中小股东利益的对策。目前，国内针对这一问题还缺乏较系统的研究和论证。因此，随着全流通时代的临近，本文对这一问题的研究，无论是从理论角度还是从实践角度，都是非常必要的，而且是紧迫的。 本文的研究结论是：控股股东的行为特征与上市公司的股权结构密切相关；后股权分置时代，控...China's securities market is experiencing from equity separation to equity full circulation, the entire market environment will undergo profound changes. As a core issue of modern corporate finance, the interest conflict between controlling shareholder and minority shareholder will demonstrate many new features in the new environment. Against this background, this paper takes listed companys’ owne...学位：经济学博士院系专业：经济学院金融系_金融学(含保险学)学号：1562007015372

Theoretical Model of Maglev Micro Assembly System and Its Realization Technology

针对现有微装配系统存在的问题,给出了一种新的理论模型;将微产品装配离散化,便于建立标准化、模块化的实用微装配系统.该模型为灵巧加工及CIMS微系统打下了基础.利用磁悬浮平台代替粗/细运动平台传送装配子单元;同时,也利用它作为微装配平台,在一个运动平台实现了粗/细运动;没有导线与运动平台相连,实现了平台的长距离运动.巧妙地利用平台运动实现线激光对微装配环境的扫描,获取微装配环境的三维信息.将全局/局部视觉系统分离,增加了操作空间.采用两种模型对磁悬浮系统进行控制,满足了粗/细运动精度.采用该理论模型可以简化系统的结构,提高装配效率.A theoretical model is presented which adopts maglev system to decompound complex problems in micro assembly and makes the system simple. This theoretical model is also convenient to constitute a standardized, modularized and practicable micro assembly system, and, furthermore, establish foundation of agile manufacture and CIMS microsystem. In the theoretical model, maglev platform is used to replace coarse-fine platform to transfer micro assembly subsystem and also used to assemble micropart, connect the platform without wire to realize a long distance movement. Line laser system scan micro assembly circumstance in the process of maglev platform movement and 3D data of microassembly is acquired. Global-local vision system are separated to widen operation space. In maglev system control, two types of dynamics model are used to satisfy the precision of coarse-fine movement. The theoretical model can reduce assembly cost of microparts and improve assembly efficiency.国家自然科学基金资助项目(50675184)

A Summary of Researches on Shareholding Structure, Dividend Policy and Corporate Governance of Listed Companies in China:Based on the Research Perspective of the Shareholding Structure Changes after the Equity Splitting Reform

股权结构是公司治理结构的基础。我国推行股权分置改革旨在优化上市公司的股权结构,提高公司治理效率。股权分置改革后上市公司股权结构发生了变化。通过研究上市公司股权结构、股利政策和再融资行为之间的关系,可以找到优化我国上市公司股权结构的目标和途径。以便针对股权分置改革后我国上市公司治理制度可能存在的缺陷,提出完善公司治理制度、保护中小投资者利益的对策建议,并指出股权分置改革后我国证券市场发展可能面临的新问题。Shareholding structure is the basis of corporate governance structure.The aim of China’s equity splitting reform is to optimize the shareholding structure of the listed companies and improve the efficiency of corporate governance.After the equity splitting reform,the shareholding structure of the listed companies has changed.Through researches on the relationships between the shareholding structure,the dividend policy and refinancing behavior of the listed companies,the aims and approaches to optimize the shareholding structure of the listed companies can be found. So that some countermeasures and suggestions can be proposed to improve the corporate governance system and protect the interests of the small and medium investors, when aiming at any flaws that may exist in the corporate governance system of the listed companies after the reform. This paper also points out some new problems that China’s stock market may be faced in the course of development after the equity splitting reform

Influence of Economic Adjustment on Chinese Commercial Banks Operation and the Counter-measures

2008年以来,在由美国次贷危机引发的全球金融危机影响下,中国经济已进入调整周期,这对商业银行的经营带来了许多影响。本文首先分析了未来中国宏观经济的发展趋势,认为此次经济调整在短期内难以结束;在此基础上,根据经济调整所引起的国家宏观政策的变化,深入剖析了造成商业银行经营不利影响的三个主要因素:净息差收窄、中间业务收入增速减缓和信贷资产质量下降;最后,本文提出中国商业银行应对宏观经济调整的四个建议:强化资产负债精细化管理、拓宽中间业务收入渠道、坚持特色定位和品牌经营、加强风险预警。Since 2008, suffering from the global financial crisis, China s economy has entered the adjustment period, whichmakes significantly influence on commercial banks operation. The paper first analyzes the development trend of China s economy in future and points out that the economic adjustment is hard to terminate in a short term. According to the changes of macro-economic policy resulting from the economic adjustment, the paper deeply scrutinizes three main factors negativelyaffecting commercial banks' operation, which are the shrinkage of net interest spread, the slowing growth of intermediary business income and the decrease of credit asset quality. The paper proposes four suggestions for Chinese commercial banking to handle the economic adjustment as follows: enhancing the sophisticated management of assets and liabilities, broadening the channel of intermediary business income, persisting the unique market positioning and brand operation, and paying attention to risk warning

基于RS的新疆哈密地区生态环境需水分析

干旱半干旱地区水资源缺乏,准确地计算区域生态环境用水和生态环境需水,可以对稀缺水资源进行合理调配,同时起到生态保护的作用。研究过程主要分为两个步骤:(1)采用RS技术,对新疆哈密地区1990年、2000年、2005年中巴资源一号卫星(China Brazil Earth Resources Sat-ellite)数据进行解译,形成1990年、2000年、2005年哈密地区土地覆被图形数据和相应的属性数据,确定相应年份各景观类型的面积;(2)参考有关研究并结合哈密地区实际情况,确定各景观类型的单位生态用水定额和需水定额,进而计算出1990年、2000年、2005年哈密地区的生态用水量,并以2005年哈密地区生态用水量为主要依据计算出保持哈密地区生态环境现状的生态需水量。研究结果表明,为了实现哈密地区生态环境整体保持在现状水平不致恶化、局部区域生态环境(巴里坤湖区)有所改善的生态治理目标,区域内生态环境需水总量为7.526×109m3,这一庞大的需水量将对该地区水资源配置造成巨大的压力;而当结合各类景观的地物空间位置特征进行分析时,发现该区域生态用(需)水量最大的景观(低覆盖草地)可以利用山地积雪融水进行自给,区域内实际需要规划配置的生态环境需水量为2.66×108m3,仅占区域生态环境需水总量的3.53%。在区域生态用(需)水计算过程中应考虑各种景观类型的生态用(需)水量的时空差异性,以保证水资源调配的科学与合理
