基于技术轨道的制造企业服务化机理研究

基于技术轨道理论与制造企业服务化间的关系，认为技术轨道对制造企业服务化的影响机理包括3类：驱动机理、拉动机理和差异化机理。制造企业服务化转型内在机理是技术轨道驱动下投入服务化、企业边界变化以及用户需求、产出、政策拉动下与技术轨道的协同演化过程，且通过技术轨道形成服务化转型差异。制造企业对自身技术轨道的识别有利于确定发展所需主要技术来源及技术演化轨迹，把握实现服务化的关键机理。     

Operational risk quantified with spectral risk measures: a refined closed-form approximation

The quantification of operational risk has become an important issue as a result of the new capital charges required by the Basel Capital Accord (Basel II) to cover the potential losses of this type of risk. In this paper, we investigate second-order approximation of operational risk quantified with spectral risk measures (OpSRMs) within the theory of second-order regular variation (2RV) and second-order subexponentiality. The result shows that asymptotically two cases (the fast convergence case and the slow convergence) arise depending on the range of the second-order parameter. We also show that the second-order approximation under 2RV is asymptotically equivalent to the slow convergence case. A number of Monte Carlo simulations for a range of empirically relevant frequency and severity distributions are employed to illustrate the performance of our second-order results. The simulation results indicate that our second-order approximations tend to reduce the estimation errors to a great degree, especially for the fast convergence case, and are able to capture the sub-extremal behavior of OpSRMs better than the first-order approximation. Our asymptotic results have implications for the regulation of financial institutions, and may provide further insights into the measurement and management of operational risk.     

金融组织强制性信息披露问题研究

由于规模经济的原因,作为信息劣势方——投资者公共利益代表者的政府必然成为强制性信忠披露的主体。政府按照参与约束原则和激励相容原则进行机制设计甄别金融组织,引导其确定合理的信忠披露边界,形成分离均衡,金融市场上的非对称信息转变为对称信息。但政府强制金融组织进行信息披露时,应尊重其利益追求和考虑金融市场发育程度等。     

The application of Operation and Technology Roadmapping to aid Singaporean SMEs identify and select emerging technologies

In order to aid Singaporean SMEs identify and select emerging technologies for business benefit, a modified process of the Cambridge T-Plan methodology has been introduced and applied to a pilot sample of 30 companies in a variety of manufacturing sectors. This fast and simple process takes the company through five key steps to enable them to create their first Operation and Technology Roadmap (OTR). The paper explains the background to the approach and focuses on the initial benefits identified by a survey of the pilot companies.     

有关台湾"大陆货品特殊防御机制"的法律思考

两岸入世后，台湾当局的大陆经贸政策与世界贸易组织的要求是有一定距离的，特别是台湾当局为大陆度身设置的“大陆货品特殊防御机制”，似乎是为了利用中国大陆在其《入世议定书》中对世贸组织成员的特别的承诺条款，但从法律角度而言，这是有违台湾在世贸组织《保障措施协议》项下的义务的，极易成为两岸之间有限的经贸互动中争端的导火绳。     

人民银行员工激励机制设计的进化博弈分析

博弈理论是当代主流经济学发展最迅速和影响最大的分支学科之一。其中,进化博弈理论由于引入了“进化稳定策略”（ESS）的概念,有效解决了博弈双方有限理性的现实问题,在解释经济管理现象时更具说服力和生命力。本文结合人民银行实际,通过构建进化博弈理论的复制动态模型,试述人民银行员工激励路径的选择及机制设计的有关问题。     

日本循环经济的运作方式及启示

日本是世界上最早探索循环经济发展模式的国家之一,也是循环经济立法最全、资源循环利用率最高的国家。日本发展循环经济是客观资源条件、经济快速增长和实现可持续发展的要求,多年来,在循环经济的实践中取得了很大的成绩,积累了丰富的经验。目前我国已充分认识到发展循环经济的重要性,日本在建立循环型社会方面的运作方式给我们提供了经验和启示。     

Nash implementation with an infinite-dimensional trade space

This paper deals with the problem of implementing the Walras correspondence via Nash equilibria, in exchange economies with infinitely many commodities and finitely many households with possibly non-ordered preferences. We explicitly construct a feasible mechanism enjoying some features, which have natural economic meanings. Under a fairly weak boundary condition, this game fully implements the Walras equilibria. If this condition is not fulfilled, our mechanism nevertheless implements the constrained Walras equilibria.

Operational Research and the environment

The discipline of Operational Research (OR) is primarily concerned with improving the effectiveness and efficiency of decision processes. These processes take place everywhere in society: industry, banking, agriculture, government, politics. Frequent use of mathematical optimization models is typical of OR. Since the early '80s these models are increasingly packaged in a user-friendly way, as Decision Support Systems. In the following we will illustrate how OR can be used to describe and solve a number of environmental problems.     

利率市场化能降低企业营运风险吗?——基于融资约束和企业金融化的双重视角

如何提高金融服务实体经济的结构性调节功能并促进企业有序运营与健康发展是金融供给侧结构性改革的重要目标。利率市场化改革作为金融领域最重要的改革之一,其在微观层面如何影响实体经济运行引起了高度关注。本文首先从理论上诠释了利率市场化通过缓解融资约束、抑制金融化进而降低企业营运风险的逻辑关系。为识别利率市场化与企业营运风险之间的因果效应,本文以中国人民银行2004年10月取消金融机构贷款利率上限和2013年7月取消金融机构贷款利率下限为外生冲击,基于融资约束差异构造准自然实验为上述理论推断提供经验证据。特别地,利率市场化每增加1单位标准差,企业营运风险平均约下降样本标准差的2.39%。异质性分析表明,利率市场化对企业营运风险的抑制效应在融资约束程度较高、行业竞争程度较高、投资机会较多的企业中尤为明显。本文研究对于进一步优化资源配置效率、实现金融与实体经济高质量发展具有一定参考意义。
