市场有效性研究一直是财务理论研究的核心内容之一 ,在金融市场理论中占有重要地位。本文从有效资本市场理论出发 ,分析了其概念、假设及其三种基本类型 ,论证了我国资本市场有效性的程度 ,并试探性地提出了在我国现有资本市场状况下企业的若干理财策略。     

异质信念资产定价研究

从随机游走、行为金融到混沌,从现代资产定价理论、行为资产定价理论到异质信念资产定价理论,3种学说和3种定价理论同时存在干当今资本市场的研究中,它们分别从不同方面、不同视角解释了资产价格的波动。本文的研究理清了3种重要定价理论之间的关系：理性与有限理性,线性与非线性,价格波动的外在机制与内在机制,为人们进一步研究资产定价理论提供了清晰的脉络。     

建构金融资本市场的“反脆弱性”机制

市场经济的道路需要大力发展金融衍生品市场,而具有高效率、高杠杆效应的当代金融市场天生是脆弱性的。金融衍生品在对冲金融市场风险的同时,也内生了自身的脆弱性。该文从如何建构金融资本市场的"反脆弱性"这个当代金融市场的风险控制难题入手,追溯金融市场在资本逻辑下的脆弱性根源,分析金融市场整体性风险的经济哲学内涵。针对历史上风险频发的金融市场,技术上寻求"去杠杆"方式的"度的守中"与弱化市场的"反身性",以及建立冗余以增强"自身免疫能力"等方法。资本逻辑根源上,从参与者主体到国家金融市场的整体性着手,充分发挥公有制为核心的"反脆弱性"优势,逐步建立起从经济理性走向政治理性的整体性风险防控机制。     

非线性技术创新评价模式研究

企业技术创新是始于研究开发而终于市场实现的动态过程,技术创新系统是由若干系统要素共同作用组成的动态复杂系统,具有开放性、动态性、非线性、不确定性等复杂性特征。传统的线性观点和线性模型已经不能适用于对技术创新系统的分析与评价,技术创新评价研究由线性、静态模式转向非线性、动态模式的发展轨迹,非线性科学的迅速发展,为更好的研究企业技术创新评价提供了重要的理论工具。本文在国内外有关企业技术创新评价方法研究的基础上,对技术创新评价有关因素,特别是对创新能力与创新环境因素作了系统分析。运用托姆尖点突变理论,分析了技术创新能力与技术创新环境对技术创新状态发生变化的内在作用机理。指出技术创新能力是技术创新状态发生变化的本质,而技术创新环境是技术创新状态发生变化的运作,并在此基础上给出了技术创新评价方法步骤。本文的研究旨在为进一步研究技术创新评价问题提供扩散性思维。     

我国股票市场分形特征的实证研究

文章分析了以EMH为基础的经典资本市场理论的局限,揭示了资本市场的分形结构特征。近20年来,作为研究非线性问题科学分支之一的分形理论,成了经济学科研究与应用的前沿领域。在此基础上文章探讨了分形时间序列的基本特征,运用R/S分析法分析了我国股票市场的分形特征,通过实证分析,总结了我国股票市场具有明显的分形特征。     

多层次资本市场与资源配置效率问题分析

一、定义资本市场的资源配置效率国外学者对资本市场效率的研究主要从微观角度出发,如资本市场有效性假说(EMH)和詹姆斯。托宾的金融市场效率观,着重从信息和价格形成方面探讨制约证券市场效率实     

金融市场的分形和混沌研究综述

主流的金融计量理论是以价格的随机游走和收益的正态分布假设为基础的,而时金融市场价格的分形和混沌研究,则从非线性的角度揭示金融价格的波动规律,并对主流金融计量理论提出了争议和挑战.本文对金融市场的分形和混沌研究做了全面综述,并进行了评价和展望.阐述了这些研究的意义,揭示了经济变量和金融市场价格的非线性特征,并对其机制进行了深入分析.不足之处是这些研究还不能很好地应用于实际经济和金融过程,去解决实际的问题.在定价、建模和预测方面还面临很多困难.对金融市场的非线性研究,让我们对现实世界的理解更加深入和精细.但这些研究并不意味着否定传统经济学理论.正是在不同理论的不断争论和互相印证的过程中,推动金融计量理论不断向前发展.     

行为金融学与非理性决策

现代金融理论是建立在资本资产定价模型(CAPM)和有效市场假说(EMH)两大基石上的.由于理性经济人假设与实际的偏差,经典现代金融学遇到了一些被称为未解之谜的现实问题,行为金融学是从人们的实际决策行为出发来研究和解释金融市场的相关问题.     

我国资本市场分形特性研究

任何科学发展,包括社会科学在内,其前沿问题都是非线性问题.但是,由于现行线性模型的简单易行,实际中仍被广泛运用.随着经济行为越来越复杂,只有用动态的非线性模型刻画某些经济现象,才能较好地反映客观现实.近二十年来,作为研究非线性问题科学分支之一的分形理论,也就成了经济学科研究与应用的前沿领域.本文探讨了分形时间序列的基本特点及Hurst指数计算方法,描述了计算时间序列Hurst指数的一般方法,运用R/S分析法分析了我国资本市场的分形特性,通过实例分析,总结了资本市场分形理论的基本内容.

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.     

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 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。
