企业的国际化感知风险对国际化绩效影响研究

以中国国际化企业为研究对象,探讨中国国际化企业的国际化感知风险对企业国际化绩效的影响。从国际化感知风险概念出发,通过引入企业资源能力(调节变量)和国际化市场进入模式(中介变量),剖析国际化感知风险对国际化绩效的影响,并在此基础上构建国际化感知风险与国际化绩效关系整合研究框架。通过对463家中国国际化企业的数据研究发现,国际化感知风险与国际化绩效之间存在显著负相关关系;国际化感知风险不仅直接作用于国际化绩效,而且还经由企业的市场进入模式间接作用于国际化绩效,即市场进入模式的中介作用显著;国际化感知风险对国际化绩效的作用受国际化经验的调节,国际化感知风险对国际化绩效的回归系数是国际化经验的二次函数。     

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.     

投资组合的行业集中度与基金业绩研究

本文探讨了投资组合的行业集中度与基金业绩之间的关系。采用Kacperczyk等的方法测量各基金的投资组合在13个行业中的资产配置情况,我们发现基金投资组合的行业集中度与基金业绩之间存在显著的负向关系,这说明行业集中度更高的基金业绩落后于那些实行分散化投资的基金。最后,不同子样本期间的考察表明结论是稳健的。因此,我们建议基金经理人在执行更为集中的行业投资策略时,应该保持谨慎的态度。     

城市路网运输性能退化成本评估模型

路网的运行受到诸多因素的影响而使得路网运输性能发生退化,分析了路网运输性能退化的影响因素和作用机理,给出了路网运输性能退化及退化的极端情况路段失效的成本分析过程框架.基于BPR路阻函数和用户均衡分配理论分析路网运输性能退化的成本函数,建立了拥堵情况下城市路网路段失效的成本评估模型.最后,通过实例分析了路网运输性能退化对出行成本影响的变化规律,给出了路网运输性能退化的极端情况路段失效成本评估的具体过程,研究表明路网运输性能退化对出行成本具有很大的影响,二者成显著的正相关关系.     

绩效考核对高校教师工作满意度的影响:职业压力的中介作用

在中国高校全面实施校内岗位津贴及配套政策的情境下,探讨绩效考核对教师工 作满意度的影响。大样本调查结果显示,绩效考核对工作满意度的影响有3条路径：绩效考核对工作满意度直接的积极影响;绩效考核通过职业压力的中介作用,间接影响工作满意度;绩效考核通过考核认知的中介作用,影响职业压力,进而影响工作满意度,其中第1条路径的影响最强,第2条路径的影响相对较弱。高校教师这一职业存在高职业满意度、低薪酬满意度并存的现象。     

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.     

A Model for Setting Performance Objectives for Salmonella in the Broiler Supply Chain

A stochastic model for setting performance objectives for Salmonella in the broiler supply chain was developed. The goal of this study was to develop a model by which performance objectives for Salmonella prevalence at various points in the production chain can be determined, based on a preset final performance objective at the end of the processing line. The transmission of Salmonella through the broiler production chain was modeled. The prevalence at flock level was calculated from the measured prevalence at sample level. The transmission model is based on data on the occurrence of Salmonella collected in the Dutch broiler production chain during several years. The developed model can be used by policymakers and industry to determine economically and politically acceptable performance objectives for various points of the production chain and to draw conclusions about which interventions are most appropriate.     

Environmental practices and firm performance in emerging markets: the mediating role of product quality

Environmental practices have not received as much research attention in emerging market contexts as traditional topics like quality. However, the importance of environmental practices for a firm’s production strategy has been increasing at an unprecedented level across the globe. Our research objective is, therefore, to investigate the interplay between environmental practices and quality in the pursuit of firm performance. Relying on 492 responses from Turkish manufacturers to test our hypotheses, we show that environmental practices directly improve the quality of products over and above the effect of quality management practices in emerging markets. Product quality, in turn, is important for increasing firm performance, acting as a mediator for the positive effects of environmental practices on performance. Thus, we reveal that product quality functions as an instrumental conduit between environmental practices and firm performance in emerging markets like Turkey where stakeholder pressures are weak, and regulations are often not properly enforced.     

Measuring operational excellence: an operational excellence profitability (OEP) approach

The pursuit of operational excellence in the manufacturing industry is at rise but its measurement still lacks of appropriate indicators to determine its financial benefits. The ambiguity is due to the impact arisen from manufacturing fluctuations such as price and cost, production mix and direct and indirect parameters variations. Manufacturing fluctuations distort the cost benefit of operational excellence. This paper, therefore, proposes the OEP (Operational Excellence Profitability) indicators to isolate the impact of manufacturing fluctuation and distinctly identify the payback of operational excellence strategies and initiatives through cost benefits of achieving higher efficiency and yield. The paper presents the conceptual and mathematical development of the proposed OEP indicators and the formulas used for their calculation. Hypothetical and industrial-based investigations and applications of the OEP indicators are conducted for their validation. The results obtained from the hypothetical exercise and industrial case suggest that OEP indicators can provide an effective cost-benefit analysis of operational excellence. This would contribute in providing manufacturing organizations with more complete information regarding the performance of their processes, which will allow their directors and managers to take better decisions related to the management and improvement of their processes.
