简析我国股市的投机性

股票市场是国民经济的晴雨表。股表市场价格上涨，交投活跃，股票市场指数逐步升高，应该反映国民经济将整体向好，同时从理论上讲，股票市场价格上升也会通过财富效应影响居民消费和企业投资，从而拉动实体经济也相应增长。当证券市场与实体经济形成良性互动时，能避免证券市场的过分波动对实体经济的伤害。当然，证券市场与实体经济的偏差是客观存在的，但如果这种偏差由于受非理性的情绪影响或宏观经济政策失调导致证券市场的股票价格过分偏离实体经济，证券市场的投机性就很大。     

中国企业股权融资偏好的寻租经济理论解释

在我国资本市场发育不成熟的宏观条件下,股票市场的股票发行审批制度正由政府主导的审批制开始向市场主导的注册制进行过渡,而具有不可避免缺陷的、过渡性的股票发行审批制创造了股市中的租金。为获取租金,未上市的企业表现出强烈的"上市偏好",而上市的企业体现的则是"股权再融资偏好",整体呈现出"中国企业的股权融资偏好"的特点。     

政策的年轮

回顾2000年,宏观经济与股票市场成为社会关注的两大焦点,股票市场不断从宏观经济基本面挖掘题材,宏观经济形势也成为影响股票市场走势的重要因素。尽管一些研究机构通过对二者之间的相关性进行定性和定量分析,得出二者的相关性不大或股票市场走势滞后于宏观经济形势等结论,但是,如果把我们国家的股票市场作为一个“政策市”来看的话,就会发现宏观经济与股票市场实际上是政府调控的左右手,二者之间的关系大大超出人们所能计算就想象的紧密程度。     

改变当前股票市场对货币政策传导弱势效应之见解

在开放和较为完善的市场经济条件下,股票市场已成为货币政策传导的主要渠道之一,中央银行制定货币政策时应考虑股票市场价格的变动.理论和实证研究表明,我国股票市场在货币政策传导中尚未充分发挥作用,如何提高股票市场在货币政策传导中的效率是当前宏观经济研究中的重要内容.     

股票市场中的政府行为

从经济学的角度来分析，股票市场中的政府行为旨在于规范市场行为，规避市场风险，提高市场效率；同时，不适当的政府行为也会造成巨额成本，影响市场的健康运作。在我国股票市场的高速发展进程中，政府在多重角色的压力下行为扭曲，造成市场偏离自身运营规律。政府的正确定位及其规范的行为，是我国股票市场长期健康发展的保障     

股票价格、宏观经济变量与货币政策——对中国金融市场的协整分析

当前中国股市暴涨暴跌从而偏离宏观经济发展方向的现象正引起人们的关注。中国股票价格与宏观经济及货币政策协整关系的实证结果表明,在中国,股票价格指数与国内生产总值及投资之间完全没有协整关系,与消费支出之间有弱协整关系,与货币供应量之间有强协整关系及格兰杰因果关系,从而检验了近些年来中国股票市场的反经济周期现象和"政策市"现象。中国金融市场的这种反经济周期现象的原因主要在于中国股票市场存在的缺陷:股票市场规模小、股市的投机色彩浓重、股市微观结构与宏观经济结构相背离。因此,深化金融市场的改革进程成为当务之急,同时对于中央银行来说,可以将一个包含了股市稳定的长期的低通货膨胀目标作为货币政策新的名义锚。     

政策效应、政策效率与政策市的实证分析

中国股票市场始于20世纪80年代初,从其不长的发展历史看,除在股票发行市场的发展初期带有一定的民间自发性外,整个发展过程都是在政府的引导和推动下成长起来的。政府不仅运用法律手段和经济手段调节股票市场的运行,而且还经常地对股票市场实施政策干预,以致人们普遍地称我国股票市场为“政策市”.由此,引申出一个非常值得研究的问题,即我国的宏观政策在多大程度上影响着股票市场的运行?其政策效应和效率如何?应当如何评价中国股票市场宏观政策?本文拟对上述问题做一实证分析。     

宏观经济环境、政府调控政策与股票市场波动性——来自中国股票市场的经验证据

以2000年1月——2008年6月的上证综合指数、宏观经济景气指数以及货币政策和财政政策的相关数据为样本,利用GARCH模型实证研究宏观经济环境、政府调控政策与中国股票市场波动性的关系。研究结果表明,中国股票市场对宏观经济环境变化的反映功能存在一定程度的缺失,财政政策的调控功能基本上处于失效状态,利率政策在现实经济环境中也未能发挥作用,货币供应量政策因其直接影响股票市场资金供给而产生了明显的影响。论文研究结果能够对中国股票市场的某些异常现象进行比较合理的解释。     

企业债券管制方式须全面改革

从中国十几年的资本市场发展来看,重点实际上集中于股票市场,股票市场所起的作用更适合经济体制改革的需要,结果使股票市场有着很强的政府导向与政策因素,由此产生了一系列问题。 一、政府管制过严 1.管制发行。(1)发行主体限制。一般说来只有国有大中型工业企业才允许申请发行企业债券,其它民营、私营、外资、涉及农业、服务业的企业不能申请发行企业债券;     

政策调整对股票市场波动的影响

以利率调整、存款准备金率调整、货币供应量变动作为货币政策调整变量,以印花税调整和财政支出变动作为财政政策调整变量,来研究股票市场的波动,分析了单个政策调整对股票市场波动的影响和政策调整组合对股票市场波动的影响。研究发现,单一货币政策中存款准备金率调整对股票市场波动性影响显著,而利率调整对股票市场波动性影响不显著。单一财政政策中印花税调整在中期对股票市场波动性影响显著。不考虑宏观经济指数变动时,只有利率调整对股票市场波动性的影响显著为负向,印花税调整和存款准备金率调整对股票市场波动性影响不显著;考虑宏观经济指数变动时,三个政策调整对股票市场波动性的影响不显著。不论是否考虑宏观经济景气指数的变动,财政支出变动对股票市场波动的影响显著负向,货币供应量变动对股票市场波动的影响显著为正。     

John Stuart Mill's Theory Of Justice

John Stuart Mill has traditionally been portrayed as self-contradictory and failing to construct a unified social theory. Recent scholarship, however, has challenged this view, finding Mill's work to be creatively synthetic in bridging the antinomies inherent in liberal democratic thought. This revisionist interpretation of Mill is advanced by an understanding of his theory of justice and its role in shaping his policy positions on issues such as welfare, education, voting rights, property rights, taxation, government intervention, and the future of capitalism.

中国养活自己能力的长期预测:技术和政策分析

中国拥有世界五分之一强的人口 ,收入又在迅速增长。因此 ,国际上很自然地会考虑或推测她在今后的几十年是否有能力养活自己。中国的人口预计将从 2 0 0 0年的 1 2 8亿增长到 2 0 2 0年的 1 4 6亿 ,和 2 0 3 0年的 1 4 9亿。与此同时 ,人均收入的增长将导致对家畜和鱼类产品更大的需求 ,因而对饲料的需求也将有很大的增长     

John Stuart Mill's Theories of Wealth and Income Distribution

Although he was much influenced by David Ricardo when he wrote the classical part of his Principles , John Stuart Mill was not a Ricardian when he penned his theories of wealth and distribution. They are based on a triple foundation. First, a belief that economics is a moral discipline. Second a theory of custom-driven human behavior. Third, an empirically formed conviction that the institutions of state, education and business cooperate to structure the distribution of income. On the basis of these presuppositions, Mill formulated 1) an institutional theory of the formation of human and non-human wealth and 2) an even more institutional theory of distribution demonstrating how the aforementioned institutions malignantly skew the distribution of income to the advantage of the propertied classes and to the extreme disadvantage of the working class. As a social economist, Mill recommended institutional reforms designed to eradicate the poverty of the working class.     

Toward a Phylogenetic Reconstruction of Organizational Life

Synopsis Classification is an important activity that facilitates theory development in many academic disciplines. Scholars in fields such as organizational science, management science and economics and have long recognized that classification offers an approach for ordering and understanding the diversity of organizational taxa (groups of one or more similar organizational entities). However, even the most prominent organizational classifications have limited utility, as they tend to be shaped by a specific research bias, inadequate units of analysis and a standard neoclassical economic view that does not naturally accommodate the disequilibrium dynamics of modern competition. The result is a relatively large number of individual and unconnected organizational classifications, which tend to ignore the processes of change responsible for organizational diversity. Collectively they fail to provide any sort of universal system for ordering, compiling and presenting knowledge on organizational diversity. This paper has two purposes. First, it reviews the general status of the major theoretical approaches to biological and organizational classification and compares the methods and resulting classifications derived from each approach. Definitions of key terms and a discussion on the three principal schools of biological classification (evolutionary systematics, phenetics and cladistics) are included in this review. Second, this paper aims to encourage critical thinking and debate about the use of the cladistic classification approach for inferring and representing the historical relationships underpinning organizational diversity. This involves examining the feasibility of applying the logic of common ancestry to populations of organizations. Consequently, this paper is exploratory and preparatory in style, with illustrations and assertions concerning the study and classification of organizational diversity.     

Information infrastructure: Who builds broadband networks?

This paper examines the essential difference between the U.S. and Japan, when one considers information infrastructure. There are seven perception gaps between the U.S. and Japan concerning Information Infrastructure policies. These gaps must be understood in order to compare the countries' governmental policies in this area. In looking at the present circumstances, the essential question to answer concerns who is to build, own and operate the network(s) of the infrastructure. Liberalization is certain to be a central factor in the ongoing telecommunications debates. Now that customers have had a taste of the liberalized market-place, the movement toward more open markets will be difficult to stop. When considering options, it is necessary to pay close attention to standardized network access and the increasingly important role software plays. These issues are causing us to take a new approach to the traditional role played by regulators. They also force a closer look at the appropriate structure of utility companies. This paper addresses the above issues in hopes of stimulating dialog on the new telecommunications infrastructure paradigm.     

海岛地区产业演替及资源基础分析--以舟山群岛为例

改革开放以来,舟山市产业构成发生了显著变化,其经济发展过程可以划分为三个阶段。1992年前,是以产业结构渔业占绝对地位的单一结构阶段;1993—1998年,以旅游业为主的第三产业快速发展阶段;上世纪末以来,又进入了新一轮的经济发展时期,即工业产值比重快速增加阶段。根据海岛的自然资源基础和特点,在新世纪的经济发展过程中,舟山市应定位为生态型的港口旅游城市。以港口及临港工业为主导,以海岛旅游和海洋经济为特色,大力发展第二产业和第三产业。海岛地区的主导产业应体现海岛资源优势及区位优势,以集群性环保型产业为主。同时由于海岛地区淡水资源缺乏,主导产业也应着重选择低耗水型产业。     

风险视角下企业治理结构和研发创新——基于委托代理模型的研究

本文基于委托代理模型,从风险的视角研究企业治理结构对研发创新能力的影响。本文构建了一个包含创新活动的委托代理模型进行理论分析,利用动态DEA 模型测算创新能力,并使用2015-2018年我国上市制造业企业数据进行实证检验。实证部分检验了理论结论:委托代理问题不利于企业提升研发创新能力,且客观风险和主观风险厌恶会加剧该负面影响。基于此,本文认为上市企业应根据企业自身研发活动特点有针对性地改善企业治理结构,提出了适当延长代理人任期、推动股权激励计划、提升代理人的风险承担能力等建议。
