改善我国股市生态的理论思考

如果从理论源头上追溯的话,传统发展观是构成我国股市生态系统脆弱的根源.股市"物理环境"即制度安排存在的巨大缺陷,股市生态系统中"生产者"生产能力低下,"生产者"与"消费者"角色错位,股市生态系统中不同"消费者"之间数量关系的失衡,股市生态系统中"分解者"的缺失,造成了我国股市生态系统的不稳定.再造健康的股市生态,我们就必须正本清源,突破传统发展观的樊篱,用科学发展观的观点认识和解决股市中的各种问题和矛盾.     

股市“稳定器”机制在我国股市中的作用研究

多年来我国股市逐步建立起一些减少市场内外冲击、稳定市场的机制,本文将这些机制概括为股市"稳定器"机制.然而,这些"稳定器"机制似乎并未有效地抑制市场波动,一些"稳定器"机制甚至在一定程度上还加剧了市场的动荡.对此,本文从稳定器的政策意图及其在我国股市失效的原因等方面进行了深入研究,并提出提高上市公司质量、回报投资者,改革发行、退市制度,引入做空机制、加快建立多层次资本市场体系,引入新型机构投资者、改进机构投资者法人治理结构,减少不必要政策因素的冲击、建立必要的市场干预机制等政策建议,上述建议将有利于改革并深化我国股市的"稳定器"机制,使之行之有效.     

脆弱的中国“股市生态”

从本质上讲，中国的股市生态就是机构这条“大鱼”靠吃散户这 条“小鱼”维持生存。盲目发展机构投资者等措施使中国的股市生态 遭到了严重的破坏，股市生态从一种状态过渡到另一种新的稳定状 态是一个极其痛苦的过程。     

小议我国股市“财富效应”及其传导机制

本文阐明了财富效应对经济增长的作用机制，并针对财富效应传导机制，从股市规模、投资者结构及收益分配结构、股市持续变动趋势、“挤出效应”等方面分析我国股市财富效应尚很微弱的原因，由此对我国股市的健康发展给出了政策建议。     

熔断机制对我国股市的影响

2015年6月中旬以来,中国股市遭遇了前所未有的股灾,面对跌跌不休的股市,市场开始呼唤熔断机制,与此同时,监管层也开始着手准备熔断机制,以更好的监控股市的不正常下跌.2015年12月4日,上交所、深交所、中金所正式发布指数熔断相关规定,熔断基准指数为沪深三百指数,采用5%和7%两档阈值,于2016年1月1日起正式实施,让人意外的是2016年1月8日,仅仅实行了四天的熔断机制被紧急叫停.熔断机制为什么会暂停、熔断机制将何去何从以及熔断机制对我国股市的影响都耐人寻味,本文试图分析.     

价值投资于中国股市的可行性分析

面对当前我国股市的低迷,各方都在探讨出路何在.有些学者认为基于中国股市现状和特殊性,价值投资并不适用.本文从理论和实证两方面,论证得出价值投资非但不是不适合中国股市,而且还是将来引导中国股市健康发展的趋势所在,在我国广大投资者中尽快建立起价值投资的理念,让以研究为主导的价值投资来引导整个市场,是解决中国股市问题的关键.     

中国股市的生态图景

相对于前几年热热闹闹红红火火的中国股市,目前中国的股市真可谓是冷冷清清凄凄惨惨.一如习惯在黑暗中为拯救苦难的同胞而振臂呐喊的鲁迅先生那样,有"中国股市鲁迅"之称的水皮先生,在<谁在鱼肉中国股市>中,对造成中国股市的如此悲惨景象进行了生动形象、入木三分的深刻剖析.     

股市泡沫循环的公共政策反应

股市泡沫循环对经济会造成负面影响,政府的理性选择是采用公共政策对股市波动做出适当反应.本文在运用内在泡沫模型分析我国股市泡沫形成机理的基础上,把内在泡沫扩展到金融加速子模型中,探求股市泡沫循环对实体经济造成影响的具体机制,并用股票收益率和贷款增长率对金融加速子进行实证检验,进而推导出公共政策工具,且对直接或间接作用于股市的公共政策做出政策评价.     

我国股市生态缺陷的表现及其恶化原因

(一)因保护不力,我国股市生态严重恶化。1.宏观经济一路走好,但股市却长期低迷。自2002年开始,我国经济步入了一个新的景气周期,2004年GDP增长率更高达9.5%,然而,股市非但没有成为国民经济向好的晴雨表,反而与国民经济走向背道而驰。如2005年8月底的上证指数仅收于1160点,与2001年6月的高点相比,跌了近50%。2.上市公司业绩不断攀升,而股价却长期走软。2002年以来,我国上市公司业绩呈现出整体逐年提高的态势。如2003年和2004年上市公司业绩分别比上年提升25%和40%。然而,股市并不为此所动,至2005年8月底,20元以上的股票已成为稀有品种,平均…     

建立有序和有效的股市退出机制

2001年4月23日,在上海证券交易所上市的PT水仙正式退市,拉开了我国证券市场上退市机制全面启动的帷幕.但是,PT水仙的退市并不意味着我国股市的退市机制已经建立并完善了,要真正建立有序和有效的股市退出机制,进而发挥退市机制在资源配置中的功能和作用,我们还有相当长的路要走,需要从宏观到微观上做出全方位的努力.     

A Rich Vein for “Reality Mining”北大核心CSSCISSCI

Arik Hesseldahl In the aftermath of the September 11 attacks, U.S. officials quickly turned their attention to other potential targets, including California's Golden Gate Bridge. What would happen if terrorists took down the bridge between San Francisco and Marin County? How much of the region would be affected and for how long?     

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.     

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.     

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     

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。
