不同趋势下股指期货价格发现功能研究

本文利用沪深300指数和沪深300股指期货当月主合约的5分钟高频数据,采用线性和非线性Granger因果检验方法,对股指期货价格发现功能进行了研究。研究结果表明,在上涨趋势中股指期货收益变化领先于现货市场收益变化,股指期货具备价格发现功能;而在下跌趋势中,股指期货收益与现货收益互为Granger因果关系,股指期货市场收益与现货市场收益存在相互引导的关系。     

我国股指期货市场与股票现货市场的价格关系——来自中国资本市场的经验证据

本文基于沪深300股指期货自2010年4月推出以来的日收盘价数据,运用协整检验、格兰杰因果检验、脉冲响应函数等方法分析股指期货市场与现货市场价格的领先滞后关系,结果发现:沪深300股指期货和沪深300指数现货价格之间存在长期稳定的协整关系,股指期货的价格引导着现货的价格,股指期货与现货指数之间存在着单向的因果关系,脉冲响应的结果也印证了期货价格对现货价格具有更大的冲击效应的结论。这说明股指期货的上市加强了现货市场的信息传导机制,股指期货市场的推进和健康发展有利于优化我国的资本市场结构。     

H股指数期货对现货市场信息效率影响的实证研究——基于非线性Granger检验

H股指数期货作为与中国内地股市关联度最高的海外股指期货,它对现货市场的影响是观察沪深300指数期货对现货市场影响的重要窗口。本文基于混合分布假说,分别利用线性Granger因果关系检验方法与非线性Granger因果关系检验方法对H股指数期货推出前后现货市场内部交易特征进行研究。研究显示:现货市场交易量与收益率之间不仅存在双向非线性Granger因果关系,并且在股指期货推出后,现货市场交易量推动价格波动的能力更强,由此表明H股指数期货降低了现货市场信息不对称,线性Granger因果关系检验方法则低估了交易量与收益率之间的内在联系。     

股指期货与现货指数之间超前滞后关系研究

利用Granger因果检验和向量自回归协整模型对股指期货与现货指数之间的超前滞后关系进行研究,运用向量自回归协整模型(VAR)画出脉冲图,通过协整分析和脉冲响应分析确定了超前滞后时间。研究结果表明:沪深300股指期货对现货指数具有4~5分钟左右的超前现象;而沪深300现货指数对股指期货不具有超前效应。研究进一步证实了沪深300股指期货的价格发现功能,为机构投资者预测现货市场走势、套期保值和规避风险提供了重要的参考依据,对于进一步促进我国资本市场的发展完善具有现实意义。     

股指期货与股票现货指数间关系研究

本文检验了沪深300股指期货和股票现货指数收益率之间的领先——滞后关系,发现股指期货和股票现货指数间存在单边关系,股指期货领先于现货指数约15分钟。另外,股指期货与现货指数都有显著的时变方差特征和波动持久性,且股指期货的波动性向现货指数单边溢出,表明股指期货对信息的反应早于现货市场。     

我国股指期货市场与股票市场溢出效应研究

运用基于结构向量自回归模型的溢出指数,检验我国沪深300股指期货与沪深300指数收益率间静态和动态的波动溢出效应和信息溢出效应。结果表明,在股指期货市场未限制交易前,我国沪深300股指期货收益率波动对沪深300指数收益率波动具有显著正向净溢出效应,沪深300股指期货成交量对沪深300指数收益率波动也具有显著正向净溢出效应;在股票市场剧烈波动时,波动溢出效应和信息溢出效应均会增加,沪深300股指期货成交量的增加会放大股指期货对现货的波动溢出效应。因此,在我国股票市场持续不稳定波动的背景下,对股指期货成交量和波动进行合理的管制,可降低期货市场对股票市场的波动溢出效应,进而有效防范资本市场风险。

基于DCC-MVGARCH模型的股指期货与股票市场动态相关性研究

沪深300股指期货的推出对中国的资本市场具有重大的历史意义,选取沪深300股指期货连续指数（IFLX）与沪深300指数（HS300）5分钟高频数据,构建DCC-MVGARCH模型来考察股指期货市场与证券市场之间的动态相关关系。研究结果表明在整个样本区间上,中国股指期货连续指数（IFLX）与对应的HS300指数收益率之间表现出一定的正动态相关性,且期现两市之间的动态相关关系除个别期间出现跳跃外,总体上稳定在0.5～0.6之间。     

非同步交易下股指期货与股票市场开收盘收益率间引导关系的实证研究

运用Granger因果检验、脉冲响应函数分析和方差分解,基于819组5分钟高频数据,对沪深300股指期货及其股票指数的开盘价格、收盘价格之间的引导关系进行检验。结果表明:期货市场与股票市场的开盘收益率相互引导;期货市场收盘收益率引导现货市场的收盘收益率和第二天开盘收益率;期货市场受自身和现货市场新息的冲击;现货市场受自身新息的冲击较大;期货市场对现货市场新息的变动更敏感;期货与现货的开盘收益率变化的总方差主要来自于现货市场,期货与现货的收盘收益率变化的总方差主要来自于期货市场。     

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.     

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。
