金融市场结构与货币政策成本传导渠道效应分析

以我国金融市场特征为变量,通过衡量利率传导程度以确定我国金融市场结构特征,运用三部门DSGE模型,分析成本渠道在货币传导机制中的表现.尽管我国利率传导程度不高,但是利率冲击对产出和价格的作用是显著的.成本渠道在发展中金融市场和发达金融市场中的表现差异较大,反映出我国金融市场体制不够健全,还存在着一定的市场摩擦,这提高了厂商与银行的交易成本;我国的制造业以劳动密集型企业为主,这种生产模式提高了企业对融资成本的敏感程度,增加了成本渠道在我国经济中的影响力.

中国OFDI影响出口的质量效应与成本效应研究——基于异质性产品价格分解模型

基于异质性产品价格分解模型，运用联合国UN Comtrade 2003-2016年产品-目的国层面出口数据，考察中国OFDI影响本国出口的质量效应和成本效应。研究发现：中国OFDI显著提升了出口产品质量，并对出口产品成本产生降低作用。从目的国收入看，金融危机前，中国OFDI对出口质量的提升以及对出口产品成本的降低作用，主要通过对高收入和中高收入国家的投资实现；而金融危机后，则主要通过对中低收入国家的投资实现。从产品类型看，中国OFDI显著提高了差异性产品和中间产品的出口质量，并对两类产品的成本产生降低作用；但对同质性产品和最终产品，只对其出口产品成本存在显著降低作用，对出口质量的提升作用不显著。因此，以投资带动贸易仍然是推动中国外贸高质量发展的有效举措。     

中小证券公司后台业务外包分析

随着证券市场的发展,各中小证券公司后台日益庞大,后台系统投入大幅增长,但业务范围和营销能力并未随之大幅增加,导致后台出现产能过剩,产生大马拉小车和IT黑洞等现象。由于成本原因,目前许多中小证券公司管理层对新系统的投入和团队建设处于彷徨境地。本文提出通过将后台业务外包,来解决中小证券公司后台成本居高不下的问题。     

Animal foods and climate change: shadowing eating practices

Animal farming exceeds all forms of transport in terms of global greenhouse gas (GHG) emissions. Despite the implications of the seriousness of addressing animal farming in relation to mitigating the effects of GHG emissions, to date, the relationship between consumer behaviour and climate change has tended to neglect the role of animal foods. This paper reports on a pilot study in which six UK households were ‘shadowed’ to facilitate the investigation of the relationship between animal food practices and environmental practices, as they emerge in day‐to‐day life. Results indicate that most participants make no connection between the two issues at present, in terms of awareness or practice. However, animal foods do have an ambiguous and complex status in most participants' food practices; for instance, being viewed as problematic for reasons of health or animal welfare. This finding suggests that further research is needed into the potential for raising awareness of the link between animal‐based foods and climate change. This might have a role to play in shifting food practices towards more plant‐based, less GHG intensive, foods.     

水电工程项目施工管理控制探析

结合工作实际,对水电施工企业如何进行施工管理控制进行了探讨。要做好水电工程项目施工管理控制,首先要确定成本目标、流通量目标和时间目标等,其次要实行全面预算管理,再次要强化制度管理。只有落实好以上工作,才能做到科学管理,精心施工,促进企业发展。     

知识经济下中医医疗服务核算问题探讨——以江苏省为例

知识资源成为医院生产要素的主要因素,其消耗也成为医疗服务成本的构成部分。现行的医院财务会计和成本管理将无形资产的价值摊入管理费用,低估创造发明医学技术、掌握和使用医学技术的人力资源的价值,显然不符合知识经济下医疗服务成本管理的内涵。本文对江苏省内不同地区的中医院的中医科室进行医疗服务成本的调研,分析了目前中医医疗服务成本核算方法中存在的问题。     

Weak Disposability in Nonparametric Production Analysis: Reply to Färe and Grosskopf

Färe and Grosskopf (this issue) claim that a single abatement factor suffices for modeling weak disposability in nonparametric production models, and that the Kuosmanen (2005) technology that uses multiple abatement factors is larger than necessary. This article demonstrates by a numerical example that a single abatement factor does not suffice to capture all feasible production plans, and that its use leads to the violation of convexity, one of the maintained assumptions of the model. We also prove that the Kuosmanen technology is the correct minimum extrapolation technology under the stated axioms.     

Competition Effects of Supermarket Services

This article investigates the competition effects of supermarket services using fluid milk as a case study. A simultaneous equation model for services and price competition is estimated with scanner data from fifteen supermarket chains using two alternative measures of services, namely store size and principal components of in-store services. Empirical results show that increasing services results in economies of scope, greater supermarket chain-level demand, lower price elasticity of demand, and enhanced market power, leading to higher milk prices and quantity sold. We conclude that, as result of service competition, supermarkets differentiate themselves from competitors and successfully attract less price-sensitive consumers.     

“交易外部性”:外部性的重新理解及系统整合

基于对外部性和交易本质的理解,当前生产外部性和消费外部性两分的观点有失偏颇。研究提出交易外部性概念,即产权交易过程中,交易一方或交易以外的行为主体的权利(束)或权利部分职能被交易另一方强制利用而未被定价或实现对等补偿的现象。据此,按照发生领域和作用主体的不同,外部性可以划分为生产外部性、消费外部性和交易外部性三类,其中,交易外部性进一步包含一类交易外部性、二类交易外部性和三类交易外部性。此处的二类交易外部性与史普博的内部性具有相同的本质内涵,即内部性实质是交易外部性范畴下的一个子分类。
