网络能力、资源获取与新企业绩效关系实证研究

网络能力是在网络导向驱动下,利用关系技巧和合作技巧进行一系列网络构建和网络管理活动,以实现资源获取目标的能力.在中国转型经济时期,网络能力对于新企业克服资源约束,实现生存和成长具有重要作用.拓展了网络能力的理论内涵,将网络能力划分为网络导向、网络构建和网络管理三个维度,建立了网络能力、资源获取与新创企业绩效关系模型,以322家新企业为样本进行实证分析.研究结果表明,网络导向对网络构建和网络管理具有显著正影响,网络构建和网络管理对知识资源获取和运营资源获取具有正影响,知识资源与新企业绩效显著正相关,知识资源获取对运营资源获取具有正影响.研究结论还表明运营资源对新企业绩效无显著影响,但知识资源可以加强两者之间关系,说明新企业只有具备很强的资源管理能力才能将运营资源转化为企业绩效.     

家长式领导、冲突与高管团队战略决策效果的关系研究

本文以四川省78家企业371名高管团队成员为实证研究对象,探讨了CEO的家长式领导行为对高管团队战略决策效果的影响,以及团队冲突在其中的中介作用.同时,构建了包括家长式领导、认知冲突、情绪冲突和决策效果四个变量的概念模型,并提出相应的理论假设.通过结构方程模型的检验,表明CEO的德行领导和威权领导分别从正反两个方向对决策效果产生显著的影响,仁慈领导对决策效果没有显著的直接影响.德行领导主要通过认知冲突作用于决策效果,仁慈、威权领导则通过情绪冲突作用于决策效果.     

承诺型人力资源管理实践、知识分享和组织创新的关系研究

在复杂多变的竞争环境中,知识密集型企业如何提高自身的知识管理能力和组织创新水平是一个重要的研究议题.尽管理论研究者已经认识到人力资源管理实践对知识分享、组织创新的影响作用,但检验这三者之间关系的经验研究迄今还不多见.本研究通过对124家知识密集型企业的实证考察发现,承诺型人力资源管理实践与知识分享之间存在显著的正相关关系;同时发现,知识分享在承诺型人力资源管理实践和组织创新之间起到了部分中介作用.我们的研究丰富了有关知识管理的文献,也为组织创新管理实践提供了有益的启示.     

A Flexible Evaluative Framework for Order Picking Systems

This paper develops a novel framework to evaluate the integral performance of order picking systems with different combinations of storage and order picking policies. The warehousing literature on order picking mostly considers minimizing either elapsed time or distance as the sole objective, whereas warehouse managers in a supply chain have to look beyond single‐dimensional performance and consider trade‐offs among different criteria. Thus managers still need a unified and efficient framework to select a portfolio of appropriate order picking policies from a multi‐criteria and contextual perspective. Our framework—combining data envelopment analysis, ranking and selection, and multiple comparisons—provides an efficient methodology to simultaneously analyze several interrelated problems in order picking systems with multiple performance attributes, such as service levels and operational costs. We demonstrate our approach through comprehensive evaluations of order picking policies in three low‐level, picker‐to‐parts rectangular warehouses facing demand variations.     

Knowledge Life Cycle,Knowledge Inventory,and Knowledge Acquisition Strategies*

For a knowledge‐ and skill‐centric organization, the process of knowledge management encompasses three important and closely related elements: (i) task assignments, (ii) knowledge acquisition through training, and (iii) maintaining a proper level of knowledge inventory among the existing workforce. Trade‐off on choices between profit maximization in the short run and agility and flexibility in the long term is a vexing problem in knowledge management. In this study, we examine the effects of different training strategies on short‐term operational efficiency and long‐term workforce flexibility. We address our research objective by developing a computational model for task and training assignment in a dynamic knowledge environment consisting of multiple distinct knowledge dimensions. Overall, we find that organizational slack is an important variable in determining the effectiveness of training strategies. Training strategies focused on the most recent skills are found to be the preferred option in most of the considered scenarios. Interestingly, increased efficiencies in training can actually create preference conflict between employees and the firm. Our findings indicate that firms facing longer knowledge life cycles, higher slack in workforce capacity, and better training efficiencies actually face more difficult challenges in knowledge management.     

A multiple-item budget-constraint newsboy problem with a reservation policy

In contrast to the classical newsboy-style problem, this paper develops a model for the multiple-item budget-constraint newsboy problem considering a reservation policy to meet marketing needs. A discount rate is provided to those customers who are willing to make a reservation. In addition to the demand from the original customers, extra demand is also included in the model due to the motivation of the discount rate. A solution algorithm, namely the MCR algorithm, is proposed to solve the problem. The proposed algorithm can actually be considered as a generalization of the classical newsboy-style problem. The MCR algorithm not only provides a business unit with the optimal order quantity, but also the discount rate necessary to achieve the maximal total expected profit under a limited budget. From the illustrated example, it is shown that the expected profit from the proposed model is greater than that from the classical model, due to the consideration of reservations, even though the budget constraint is tight. The increase in the expected profit could be treated as an information value from the willingness function. Although the proposed model is developed for multiple-item problems, it also can be applied to single-item ones. From the sensitivity analysis, the application of the single-item problem to the proposed model can still obtain greater expected profit than the classical model under different budgetary levels.     

企业IT能力系统动态演变的分析模型研究

揭示企业IT能力的演变规律,有助于把握影响IT能力系统的关键因素,从而提高企业信息系统的应用效果。本文以系统观为基础,依据协同学理论,讨论了企业IT能力系统的概念及其构成,探讨了企业IT能力系统的协同特征,提出了企业IT能力成熟度作为企业IT能力系统序参量的五种状态特征,并建立了企业IT能力系统的序参量方程,最后构造了该系统动态演化机制理论模型。     

多忠诚顾客与单一忠诚顾客差异比较研究

随着市场竞争和产品同质化的加剧,多忠诚顾客已成为现实中普遍存在的消费群体。过去有关研究都没有清晰分辨多忠诚和单一忠诚顾客,所得结论的普适性值得怀疑。本文分析了多忠诚和单一忠诚顾客在忠诚的前导和结果变量上所存在的差异,研究发现多忠诚顾客的信任、感知价值、承诺低于单一忠诚顾客;感知风险、价格敏感、口碑效应高于单一忠诚顾客;二者的满意水平没有显著差异。结论对营销者进行市场细分和顾客关系管理具有重要意义。     

基于投入产出技术的能源效率新指标——生产能耗综合指数

随着全世界对能源需求的增加,以及全球气候变化之于人类的负面影响逐渐加剧,能源效率的高低已成为衡量一国经济、政治和环境发展的重要标志。但是现有的能源效率指标在国内国际比较中并不能更好的发挥作用,鉴于此,本文在投入产出技术框架下,提出生产能耗综合指数这一比较能源效率的新指标,以此能更加完善我国能源效率的评价体系,更加科学合理的指导经济建设,指明节能工作的主要方向。     

基于EMSR方法的订单接受策略研究

选择性的订单接受策略对于按订单生产的制造型企业具有重要意义。本文在单一资源的情况下,采用收益管理中常用的期望边际座位收益EMSR-a和EMSR-b方法,分别得出了利润最大化的订单接受策略。然后,把这两种策略运用到一个算例,与FCFS策略进行比较。数据结果显示在企业利润方面,这两种策略都明显优于FCFS,利润均提高20%以上。
