A bootstrap-assisted spectral test of white noise under unknown dependence

To test for the white noise null hypothesis, we study the Cramér-von Mises test statistic that is based on the sample spectral distribution function. Since the critical values of the test statistic are difficult to obtain, we propose a blockwise wild bootstrap procedure to approximate its asymptotic null distribution. Using a Hilbert space approach, we establish the weak convergence of the difference between the sample spectral distribution function and the true spectral distribution function, as well as the consistency of bootstrap approximation under mild assumptions. Finite sample results from a simulation study and an empirical data analysis are also reported.     

一种战略性选择:企业慈善社会责任

西方企业普遍实行战略性慈善捐助,强调企业的慈善捐助行为与企业相关利益者利益的兼容性。迈克尔·波特将其竞争优势理论运用于企业慈善行为的分析,最终形成独树一帜的战略性企业慈善行为理论。企业慈善捐助应该以一种能增加企业资源和利润的方式来进行,这对于我国企业选择承担慈善社会责任的模式有重要启示。中国企业应增强对慈善捐助在企业发展战略中地位的认识,把履行企业慈善社会责任与企业发展战略统一起来,作为一种战略性选择。     

环境规制与企业技术创新研究——基于我国30个省份数据的实证研究

经济发展带来的环境污染问题越来越受到人们的关注,如何处理好环境规制与经济增长方式转变之间的关系成为学界研究的热点。关于企业创新与环境规制的问题,国内外学者一直存在不同见解。基于2001-2009年30个省市的数据,对我国企业技术进步与环境规制之间的关联进行了实证研究。结果表明,环境规制对企业技术进步的影响并不显著,相对而言,经济规模以及政府促进政策对企业技术进步的影响更显著。最后,提出了相应的政策建议。     

生产价格理论的另类思考及李嘉图难题的另解

传统观点认为,生产价格理论解决了李嘉图难题之一——劳动价值论所强调之等价交换原则与等量资本获取等量利润规律之间存在冲突.这个判断是不能成立的,生产价格理论只是绕开李嘉图难题从总量层面证明了劳动价值论,而且其证明的理论结构是存在逻辑缺陷的.这个李嘉图难题的存在源于其方法上的错误——混淆了动态与静态、非均衡与均衡、现象与本质.如果避免了李嘉图的方法性错误,不仅这个难题会消失,还可以将劳动价值论的证明从结构层面向前推进一步.     

萨丕尔-沃尔夫假设之下的汉英亲属称谓研究

汉英亲属称谓之间存在着巨大的差异,本文以萨丕尔-沃尔夫假设为理论基础,认为不同的亲属称谓系统决定语言使用者对亲属关系不同的认知方式,同时,不同的亲属称谓系统也反映出语言使用者对亲属关系独特的认知方式。     

两类人假说——中国经济学的一个理论支柱

经济活动有两类人参与:一是从事生产交换活动的人,是为私家人(经济人);二是为经济活动建立制度规则、维持秩序的人,是为公务人.古代和近代是一种小规模生产,制度规则长期固定,公务人的参与被遮蔽,只显示出私家人活动,由此亚当·斯密提出了经济人假说.工业革命后,生产走向社会化,制度规则的变革加快,公务人与公务活动的作用增大.而在西方国家,资本主义市场经济占统治地位,这种制度凸显私家人,因而在西方经济学各种理论框架中,经济人假说是一大理论支柱.社会主义市场经济以公有制为主体,公务人与公务活动的作用更大,两类人假说更为适用,可为开创21世纪中国经济学提供一个理论支柱.     

中国农村的收入差距与健康

随着收入差距的扩大,收入分配对健康和健康不平等的影响日益受到关注。本文利用中国健康营养调查(CHNS)1997年和2000年农村的面板数据回答两个问题:收入差距对健康的影响以及影响健康的方式;收入差距的扩大是否会导致健康不平等的加剧,尤其是低收入人群的健康是否受到更为不利的影响。研究发现,首先收入差距对健康的影响存在滞后效应;其次,收入差距对健康的影响呈现“倒U”型,在收入差距较高时,收入差距对健康的影响主要为负向的,一个可能的原因是收入差距影响到公共卫生设施的供给。再次,收入差距的扩大会加强收入效应,其含义是如果低收入人群的收入更容易受到负向冲击,那么收入差距对低收入人群的健康更为不利。     

私募股权投资基金公司战略规划

对于传统的金融投资而言,风险投资是一种观念和方法的革新,传统金融投资着眼点是未来的现金流量,而风险投资更为关注被投资企业管理者的能力、技术以及企业的发展前景等,因此受金融市场的总体趋势、政府政策导向、科技发展水平等宏观环境影响较大。正确把握好宏观环境发展趋势,对于私募股权投资公司战略分析和战略选择尤为重要。本文采取了PEST、波特五力模型、SWOT矩阵等多种方法,在详细讨论宏观环境、公司竞争环境、公司现状的基础上,总结了H私募股权投资基金公司的优势与不足,得到了公司战略目标、战略规划以及5大战略重点。本文的研究意义在于为H私募股权投资基金公司制定战略地图以及基于平衡积分卡的绩效管理体系奠定基础。     

Thailand wine tourism: a dream or a reality?

Conventionally, wine tourism is mainly popular in Australia, New Zealand, South Africa and the Europe regions. Interestingly, Thailand, despite being a young wine-producing country, has emerged as a potential wine tourism provider within the Southeast Asia regions. This research aimed to evaluate the competitiveness of Thailand wine tourism’s within its regional growth. Porter’s Four Diamond Model was used as a tool to assess this industry competitiveness. Three wineries in Thailand were visited and qualitative approaches comprising interview and observation were utilized as the means of data collection. Triangulation was used to analyze the reliability of the data gathered. The finding showed that wine tourism in Thailand was still an infant industry as most tourists and tourism operators were still not aware of the product offered. However, the wineries themselves had already owned the competency to serve the market.     

An assessment of delivery changes for UK terminal air navigation services

In order to meet government contestability policy ambitions, the United Kingdom Civil Aviation Authority (CAA) has undertaken a range of initiatives to create a competitive market for terminal air navigation services (TANS). This paper examines the critical dynamics underlying recent TANS service delivery changes at the nine United Kingdom airports that fall within the Single European Sky performance scheme (SES) using industry data and Porter's five forces model. Interviews with CAA, NATS and airport operators, along with publically available material, are used to explore the various elements impacting competition for TANS at these airports. Competition is intense among a very small number of companies. In addition to optimizing service cost, airport operators require greater value for money including alignment to strategic-operational goals, closer integration with other airside functions and payment structures that are performance based. Gatwick and Birmingham airports changed service provisions due to concerns about the value for money proposition offered by NATS Services Ltd (NSL). This paper also illustrates how competition has changed the customer orientation of NSL. It has been forced to evolve quickly from an expensive, perceived as somewhat arrogant, organisation to one that must be capable of aligning to the cost and service requirements of its customers. Importantly for the ATM industry this paper provides evidence that competition drives lower service costs and provides greater value for money for airlines and airport operators.
