Optimization of the machining economics problem under the failure replacement strategy

This paper presents a model for calculating the optimal cutting feed rate and spindle speed in a stand-alone cutting machine. The optimal cutting conditions are determined for three different objective functions—minimum expected cycle time, minimum expected cost per unit, and maximum expected profit-rate—under the failure replacement strategy, taking into account cutting tool constraints and machine limitations. We also examine the relationships between the optimal solutions, and present the efficiency range of feed rate.     

Sustaining Collusion Via a Fuzzy Trigger

Probability theory is the standard economic representation of uncertainty, although it is not always an accurate one. Fuzzy logic is an alternative representation that does not require individual beliefs regarding the explicit functional form of uncertainty. This paper applies fuzzy logic to an oligopoly trigger pricing game. The fuzzy trigger pricing game reverses the standard cyclical price war prediction; collusion-sustaining price wars are most likely to occur during times of high demand. The fuzzy model also predicts that markets with relatively volatile prices are more likely to undergo collusion-sustaining price wars. The predictions are consistent with available empirical evidence.     

创新驱动产业转型升级研究——基于中国1998-2016年省域面板数据

为了探究创新驱动产业转型升级的作用机制,构建了创新投入与创新产出对产业转型升级内涵质量与外显效应的影响模型,并提出研究假设。基于中国1998-2016年省域面板数据,借助Eviews 9.0计量软件,采用固定效应模型进行实证研究。结果表明,所提出的研究假设均得到验证。创新产出对产业转型升级内涵质量具有积极影响,创新产出的各表征变量(专利授权数、技术市场合同成交金额、新产品销售收入)每增长1%,产业转型升级内涵质量的表征变量人均国内生产总值将提高0.014 8%～0.051 1%。创新投入对产业转型升级外显效应具有积极影响,创新投入的各表征变量(R&D经费内部支出、R&D人员全时当量)每增加1%,产业转型升级外显效应的表征变量产业结构层次系数将提高0.007 1%～0.010 5%。因此,创新能够驱动产业转型升级,但创新投入与创新产出对产业转型升级的影响机制并不相同。研究结果为创新驱动产业转型升级问题的研究提供了一个新的研究范式,对实施创新驱动发展战略、促进产业转型升级有借鉴意义。     

组织文化量表研究综述及评析

越来越多的学者采用实证方法研究组织文化,如何测量组织文化受到前所未有的关注.量表是测量组织文化的重要工具,正确设计或选择量表直接影响着研究成果.虽然使用量表研究组织文化已成为新的趋势,但国内外对组织文化量表进行全面系统综述的文献较少.文章首先分析组织文化研究方法,然后对比各类已开发的组织文化量表,最后提出设计与运用组织文化量表的建议.文章试图通过对组织文化量表进行全面系统地综述,为设计与使用组织文化量表提供参考.     

TOWARD BRIDGING THE GAP BETWEEN THEORY AND EMPIRICAL REALITY

Introductory (i.e. first year) undergraduate learners often perceive economics to be remote from reality and overly theoretical, leading to a lack of motivation and enthusiasm to study economics. A general survey of curriculum practice reveals that lecture materials and the pedagogic approach to teaching introductory economics often do not place the current “mainstream” economic theory into its philosophical context. The result being that the learners are unable to bridge the gap between abstract economic theory and empirical reality. This paper argues that research into effective teaching and learning should focus not only on learner characteristics but also on curriculum content and its philosophical underpinnings, in order to research why students hold these negative perceptions. The paper recommends that introductory undergraduate teaching needs to engage in a critical examination, with the learner, of the philosophical underpinnings of “mainstream” economic theory and to introduce debates about the implications of these into the curriculum. This would create exciting new opportunities for teachers and learners to explore the connections between economic theory and social science in general and should come a long way in changing the negative perceptions of introductory undergraduate economics.     

农村金融体系的制度创新

我国现有农村金融体系的制度性缺陷已成为制约解决“三农”问题的瓶颈,阻碍了金融与经济的良性循环,已不适应农业和农村经济发展的需要。以制度经济学为理论依据,可以发现制度变迁的路径依赖、制度变迁的成本和公共选择的结果影响着我国农村金融体系的制度变迁,所以说制度创新是发展农村金融体系的根本途径。     

Organizational Culture,Leadership Behaviors,and Employee Attitude in Chinese SMEs＂ Empirical Evidence

This study examines the impact of organizational culture on leadership behaviors, as well as the influence of leadership behaviors on employee attitude in Chinese small and medium-sized enterprises （SMEs）. Based on previous researches, this study establishes a conceptual model that indicates the two types of influential relationship. Data are collected from 515 subordinates of 23 SMEs in Chengdu of Sichuan province. By using statistical methods, findings of this study are concluded. Directions for future research are also discussed.     

薪酬分配公平与OCB之间关系的作用研究——价值认同的调节作用

薪酬管理的公平始于对组织分配公平的研究,文章具体考察了薪酬分配公平分别对于指向个体的与指向组织的公民行为的影响作用,并从价值观契合的理论视角解释了员工对组织的价值认同对其组织公民行为所产生的影响,并在此基础上进一步构建了价值认同对薪酬分配公平感与组织公民行为之间关系的调节效应模型。本研究的结果表明,薪酬分配公平与组织公民行为(包括指向个体的与指向组织的)都具有显著的正相关关系,而且员工个体对组织的价值认同能够负向调节这二者之间的关系,降低由于薪酬分配不公平所导致的组织公民行为投入减少的负面效果。依据研究结果,指出未来的薪酬管理实践可以通过改善员工对组织价值观的认同状态,以使组织得到期望的产出。
