图书馆服务质量评价模型研究

图书馆服务质量是不同属性的综合体,它包括许多很难被测量的不可感知属性,这种特性给被测者在接受问卷调查时带来了一些困难.为了避免上述情况出现,在分析了图书馆服务质量综合评价中现存主要问题和影响因素的基础上,建立了基于灰色局势决策的模糊多属性决策模型,将灰色系统和模糊集理论引入定性指标值的测度中,得到了满意的结果.     

The Effects of Competitive Environment on Supply Chain Information Sharing and Performance: An Empirical Study in China

Information sharing in supply chains has become an important topic over the past decade. This study uses data from 617 Chinese manufacturing firms to investigate the relationships among competitive environments, supply chain information sharing (SCIS), and supply chain performance. The results of structural equation modeling analysis show that (i) international competition is positively related to all three types of SCIS whereas local competition is not significantly related to any of the three types, (ii) internal information sharing is positively related to external information sharing with suppliers and customers, and (iii) internal information sharing and information sharing with customers are positively related to superior supply chain performance, whereas supplier information sharing is not significantly related to performance. The findings enhance our understanding of the relationships among competitive environment, SCIS, and supply chain performance in Chinese manufacturing settings.     

考虑公平偏好的低碳化供应链两部定价契约协调

在供应链低碳化背景下,研究了具有公平偏好的制造商向零售商提供两部定价契约的供应链协调问题。分别讨论了零售商是否具有公平偏好的情况,通过模型求解得到实现供应链协调的契约参数及利润分配方案。研究发现,当仅有制造商具有公平偏好时,两部定价契约可以实现供应链协调;当制造商和零售商均具有公平偏好时,在竞争型渠道中,特定参数制约下两部定价契约不能够协调供应链,而在和谐型渠道中仍能协调供应链,制造商占有的渠道利润随零售商公平偏好的程度而不同。     

Linking perceived organizational support with employee work outcomes in a Chinese context: Organizational identification as a mediator

Perceived organizational support (POS) is viewed as an important explanatory framework for understanding the relationship between employees and the workplace, and is regarded by some researchers as central in understanding job-related attitudes and behaviors of employees. However, less research has taken into account the role of organizational identification, which reflects how individuals define the self with respect to their organization, as a potential influence on such relationships. Drawing on a cross-organizational sample of 238 subordinate-supervisor dyads from the People’s Republic of China, we examined whether organizational identification mediates the effect of perceived organizational support (POS) on work outcomes including turnover intentions, work performance, and organizational citizenship behavior (OCB). Results from the current study showed that organizational identification fully mediates the relation of POS to OCB-directed to individuals, and partially mediates relations between POS and other work outcomes (turnover intention, work performance, OCB-directed to organization). Implications for management theory and practice are discussed.

试论中国股票市场失衡及其与宏观经济运行态势的背离

本文建立了考察股市运行失衡与宏观经济运行态势背离的分析框架.作者认为,只有将股市放到宏观经济运行的大背景下,从股市与宏观经济的互动机制角度来考察,才能全面认识和把握股市运行的规律.因此,本文从股票价格波动、通货膨胀、股票市场规模等角度进行了系统分析.通过与美国、韩国股市有关实证分析结果的比较,本文提出,正是由于中国股市的经常性失衡,完善市场经济条件下股票市场与宏观经济运行的正常互动关系才被打乱,表现为股市不能正常反映宏观经济波动状况,二者走势出现明显的异动和背离.     

The Impact of Competitive Strategy and Supply Chain Strategy on Business Performance: The Role of Environmental Uncertainty*

This article investigates the relationships among competitive strategy, supply chain strategy, and business performance while examining the moderating effect of environmental uncertainty. A total of 604 questionnaires were collected from three cities in China, and the statistical results show significant moderating effects of external environment on the relationships among competitive strategy, supply chain strategy, and business performance. Firms that primarily focus on a differentiation strategy emphasize an agile supply chain strategy. Cost leaders are inclined to implement both lean and agile supply chain strategies, but their emphasis on agile strategy is significantly greater in a volatile environment than in a stable environment. The choice of supply chain strategy does not appear to be an “either‐or” decision and firms could adopt either a lean or an agile strategy, or both, depending on the environment. This article provides significant managerial implications for supply chain practitioners to co‐align supply chain strategy and competitive strategy with the environment to improve performance.     

Optimal ordering and pricing decisions for a target oriented newsvendor

This paper is the first to study pricing and target oriented decision making together in the newsvendor model. Specifically, this paper studies a newsvendor who decides on order quantity and selling price to maximize the probability of achieving both profit and revenue targets simultaneously. First, it is shown that the probability of a newsvendor achieving both targets depends critically on the relative magnitudes of the profit margin and the ratio between the profit target and the revenue target. Second, the closed-form expressions of the optimal order quantity, the optimal selling price, and the maximal profit and revenue probability are obtained. It is shown that if the product has greater price elasticity, the best strategy is always to price lower and order more.     

基于Nash均衡约束的竞争性评估方法研究

基于多指标决策模型(MCDM),研究了在Nash均衡约束的基础上,如何根据各决策单元(DMU)本身的特点来获取不同DMU的优势权重从而达到最终决策时自身的优势最大化.从新的角度,引入Nash均衡约束,提出了基于Nash均衡约束的多指标决策竞争性评估模型.在主体自身优势最大化的基础上,增加Nash均衡约束,通过约束参数的不断迭代,达到各决策单元的优势均衡,给出了一种新的基于优势均衡的客观确定权重的方法.
