冷链物流外包中的质量博弈分析

通过构建并分析冷链物流外包中制造商与第三方物流提供商质量投入的几个博弈模型,得出尽管合作博弈均衡下的渠道总收益最大,但是第三方物流提供商更愿意采取主从博弈结构。     

Seasonality and momentum across national equity markets

This paper examines seasonality and momentum jointly across national equity markets at the index level. We find that seasonality and momentum are almost uncorrelated and appear to arise from different global or local risk factors, rather than from different loadings on the same risk factors. Employing a trading strategy that integrates seasonality and momentum parametrically, we confirm our conclusion about the relationship between seasonality and momentum: while the pure seasonality and momentum strategies individually generate sizable and significant returns, the combination strategy significantly outperforms the pure strategies in a way that is quantitatively consistent with their lack of correlation.

绿色食品的标识资产管理——理论框架与实证分析

绿色食品的标识资产是绿色营销中的一个新课题,借鉴品牌资产的概念,定义了绿色标识资产,并对绿色标识资产的关键驱动因素和对顾客忠诚的影响进行了系统的理论分析和实证研究。通过构建基于偏最小二乘法的结构方程模型发现,标识联想、标识感知质量和消费者介入程度对绿色标识资产起正向影响作用,进而对顾客忠诚产生显著、积极的影响。     

瞪羚企业认定是否提高了企业创新质量

瞪羚企业认定是我国创新驱动发展战略的重要措施,旨在培育高科技、高成长性企业,促进科技进步和经济高质量发展。为研究瞪羚企业认定能否切实提升企业创新质量,利用2005-2018年新三板企业数据和PSM-DID方法研究瞪羚企业认定对企业创新质量的影响及作用机制。结果发现：①瞪羚企业认定对企业创新质量有正向促进效应,且这种效应在地区和企业层面均存在异质性;②人力投入是瞪羚企业认定发挥作用的重要渠道;③制度因素对瞪羚企业认定影响的调节效应有限,意味着我国市场化改革和知识产权保护工作仍需进一步完善。最后,为政府有效开展瞪羚企业认定工作、促进企业提高创新质量提出政策建议。     

“强监督”还是“搭便车”：自然人大股东如何影响企业专利质量

通过构建改进的知识宽度法测算企业专利质量,并以2007—2016年中国沪深A股上市公司为样本,分析自然人大股东对企业专利质量的影响以及在不同类型企业中其作用的差异性。结果表明,作为“强力监督者”,自然人大股东能够促进企业专利质量提高。但因为其角色由“强监督”转变为“搭便车”,故这种促进作用在国有企业和具有政治关联的企业中并不存在。进一步研究表明,促进作用是通过加强对经理人和研发人员的监督,减少其控制权下投机性创新策略,提升其工作努力程度实现的。研究结论为促进国有企业与民营企业创新能力提升提供相应的政策启示。     

Vertical Innovation and Catching-Up: Implications of EU Integration for CEECs-5

We analyze the role of vertical innovation in trade patterns for developing economies trading with technologically advanced countries. A model is presented where the international diffusion of knowledge, promoted by economic integration, is the source of a technological catching up and leads to a convergence in the quality of traded goods, with a positive effect on exports. We then turn our attention on the evolution of trade between the Central and Eastern European countries (CEECs-5) and their European Union partner countries, assessing whether economic integration has increase the quality of the goods produced. For the period 1995–2005, we find evidence of the increasing role of intra-industry trade and vertical differentiation and a process of specialization in higher quality products, especially in the medium- and high-skill sectors.

Complementarity and the Measurement of Individual Risk Tradeoffs: Accounting for Quantity and Quality of Life Effects

This paper considers the factors responsible for differences with age in estimates of the wage compensation an individual requires to accept increased occupational fatality risk. We derive a relationship between the value of a statistical life (VSL) and the degree of complementarity between consumption and labor supplied when health status serves as a potential source of variation in this relationship. Our empirical analysis finds that variations in an individual’s health status or quality of life and anticipated longevity threats lead to significant differences in the estimated wage/risk tradeoffs. We describe how extensions to the specification of hedonic wage models, including measures for quality of life and anticipated longevity threats, help to explain the diversity in past studies examining how the estimated wage–risk tradeoff changes with age.      

亚洲健康相关生命质量工具概况及其发展建议

目的:介绍健康相关生命质量(HR-QOL)的概念,并对在亚洲国家应用HR-QOL工具提供帮助和建议。方法:在回顾国内外相关文献的基础上,总结亚洲国家可获得的HR-QOL测量量表,并举例说明HR-QOL在亚洲应用过程中存在的问题。结果与结论:HR-QOL工具在亚洲国家的应用绝大部分属于翻译和修改现存的工具,翻译的质量、版权等问题影响着翻译后的量表效度,另外量表管理模式以及亚洲各国的文化特点等都影响着HR-QOL工具在亚洲国家的发展。     

中国工业部门要素分配份额决定因素研究

本文讨论我国工业部门要素分配份额的决定因素问题。在标准的新古典要素分配份额模型中,本文引入Dixit-Stiglitz垄断竞争以及企业目标函数的差异,建立了要素分配份额的决定模型。根据这个理论模型,本文建立了中国工业部门要素分配份额的计量模型,并利用系统GMM方法进行估计。回归结果表明,垄断能力越高,资本收入份额越高,国有和非国有企业的资本收入份额存在明显差异,国有企业的资本收入份额明显低于非国有企业,各类经济性质企业的资本收入份额从高到低依次为外商投资企业、港澳台企业、法人投资企业、集体企业、私有企业和国有企业。传统新古典分配模型考虑的技术因素,包括要素投入比的变化和技术进步,对要素分配份额的变化没有显著影响,表明我国工业部门要素替代弹性为1,因而劳动与资本相对价格的变化对要素分配份额没有显著影响。我们的结论是,工业部门要素分配份额变化的主要原因是产品市场垄断增加和国有部门改制引起的劳动力市场环境改变。
