构建铁路集装箱企业级信息平台的研究

从信息化建设角度提出了建设信息高度共享与集成的铁路集装箱企业级信息平台,该信息平台建立在铁路集装箱运输支撑体系和营销服务支撑体系之上,业务范围覆盖总公司、各级分公司和各中心站、专办站、代办站三个层次,功能包含不同层次的多个业务系统,研究归纳了平台的基本定义、总体建设目标,讨论了平台中各组成部分的功能要求和运营管理模式,并阐述了该信息平台与既有TMIS和DMIS系统的内在关系等问题.     

研发人员激励制度对企业技术创新能力影响程度的实证研究——以科技型中小企业为例

知识经济背景下,研发人员成为企业创新的核心人才之一,在促进企业技术创新能力提升和增强方面起着极为关键的作用。针对企业中的研发人员,如何制定相应的激励制度对其进行激励,尤其是研究不同激励制度在提高企业技术创新能力时的影响程度,是学术界和企业界共同关注的焦点。文章在对研发人员激励制度和企业技术创新能力相关内容整理分析的基础上,建立了研发人员激励制度对企业技术创新能力影响的理论模型,提出了影响程度假设,并以郑州市科技型中小企业为研究对象进行实证研究。研究结果证实了股权激励制度和薪酬福利激励制度对提高企业技术创新能力的影响最明显,培训、发展和环境激励制度的影响次之,成就激励制度的影响最小,最终得出物质激励制度在研发人员心中仍然占据着重要的地位。     

The short of it: Investor sentiment and anomalies

This study explores the role of investor sentiment in a broad set of anomalies in cross-sectional stock returns. We consider a setting in which the presence of market-wide sentiment is combined with the argument that overpricing should be more prevalent than underpricing, due to short-sale impediments. Long-short strategies that exploit the anomalies exhibit profits consistent with this setting. First, each anomaly is stronger (its long-short strategy is more profitable) following high levels of sentiment. Second, the short leg of each strategy is more profitable following high sentiment. Finally, sentiment exhibits no relation to returns on the long legs of the strategies.     

Mapping verbal responses to numerical scales in the analytic hierarchy process

Central to the analytic hierarchy process (AHP) are the pairwise comparisons between decision alternatives that are elicited either verbally or numerically. Since comparisons expressed in numbers are required to compute importance weights in the approach, all verbal judgments must be quantified. We propose new scales, and develop a way to identify which numerical scale is best for a given individual. The approach is based on newly-designed compound operation of decision-makers’ preference judgments. We illustrate this process with two examples.     

企业突破性技术持续采用意愿的驱动机制研究

整合组织动机和期望确认理论,从购买动机视角探讨企业突破性技术持续采用意愿的驱动机制。将购买动机分为效率动机、规范趋同动机和模仿趋同动机,阐述购买动机对突破性技术持续采用意愿影响的微观机理。以198家购买过云计算技术的企业为研究样本,实证检验购买动机与突破性技术持续采用意愿间的关系,并检验满意和认知锁定的中介效应。结果表明：购买动机正向影响突破性技术持续采用意愿,满意和认知锁定在购买动机与突破性技术持续采用意愿之间起中介作用,各购买动机的中介作用路径呈现差异化。其中,效率动机的作用路径被满意和认知锁定部分中介,模仿趋同动机的作用路径被满意部分中介,规范趋同动机的作用路径被认知锁定部分中介。研究结论打开了企业突破性技术持续采用意愿的“黑箱”,对于企业深入理解突破性技术持续采用意愿的驱动机制,促进突破性技术在持续采用过程中发挥真正价值具有重要借鉴意义。     

An empirical evaluation of China’s monetary policies

This paper investigates the responsiveness of the Chinese government’s monetary policies in terms of the money supply and interest rates to economic conditions and the effectiveness of these policies in achieving the goals of stimulating economic growth and controlling inflation. We analyze the responsiveness and effectiveness by estimating the Taylor rule, the McCallum rule, and a vector autoregressive model using quarterly data in the period of 1992-2009. The results show that, overall, the monetary policy variables respond to economic growth and the inflation rate, but the magnitudes of the responses are much weaker than those observed in market economies. Money supply responded actively to both the inflation rate and the real output and had certain effects on the future inflation rates and real output. The official interest rates, on the other hand, responded passively to the inflation rate and did not respond to the real output. They do not have any effect on future inflation rates and real output either.

Collusion and Information Exchange

Antitrust authorities view that exchange of individual firms’ sales data is more anti‐competitive than that of aggregate sales data. In this paper, I survey antitrust implications of such inter‐firm information exchange. I argue that both types of information exchange are anti‐competitive under some circumstances. More precisely, I compare profits when each type of information exchange is allowed to that when firms can only observe their own sales (Stigler’s secret price‐cutting model), and the former is bigger than the latter. I also provide a general method to bound the equilibrium profits without such information exchange.     

试论消费决策与幸福:动机-精神力场-行为假说

精神与物质并非全然等价,漠视心理机制,侈言幸福。本文不仅内生化传统经济学的偏好,引入心理学对人类心智需求的观点,建构一套同时考虑物质与精神需求的幸福模型(动机—精神力场—行为假说),考量情绪与理智并存以及交互运作的本质。模型中理性的代理人透过消费与心理特征取得,达成目标;而掌管情绪系统的委托人除根据本能性、社会性与潜在的我世界三种动机,订定目标外,也对代理人的行为结果进行幸福评价。本模型不仅更完整呈现幸福的形成与演进,也揭示多元的心理哲学意涵,并合理解释若干幸福的疑义。     

论科学与人文的内在统一性

人文从其本质上说是对理想的人、理想的人性和理想的人的存在方式的构建和培育,科学作为人类的一种文化和精神活动,在内在的精神层面和价值观念上,与人文具有统一性,科学在本质上是人文的。
