MANAGING CHANGE IN SUPPLY CHAINS: A PROCESS COMPARISON

The coordination required to successfully implement supply chain initiatives suggest that supply chain management change processes may possess some unique characteristics. Yet, empirical studies are scarce to support this logic. Using an empirical design and data obtained from managers, and drawing largely from Lewin's change process conceptualization, this study compares the process of supply chain management change to non‐supply chain management change. Further investigation into monitoring and control of supply chain management change is advised.

On the evolution of the spatial economy with multi-unit · multi-plant firms: the impact of IT development

This paper examines how the decline of communication costs between management and production facilities within firms and the decrease in trade costs of manufactured goods affect the spatial organization of a two-region economy with multi-unit·multi-plant firms. The development of information technology decreases the costs of communication and trade costs. Thus, the fragmentation of firms is promoted. Our result indicates that, with decreasing communication costs, firms producing low trade-cost goods (such as electronics products) tend to concentrate their manufacturing plants in low wage countries. In contrast, firms producing high trade-cost products (such as automobiles) tend to have multiple plants serving to segmented markets, even in the absence of wage differentials.Received: November 2004, Accepted: March 2005, JEL Classification: F12, L13, R13Masahisa Fujita: Correspondence toWe are very grateful to J.

CUSTOMER SERVICE IN THE INTERNET‐ENABLED LOGISTICS SUPPLY CHAIN: WEBSITE DESIGN ANTECEDENTS AND LOYALTY EFFECTS

This article extends the existing research on logistics customer service‐loyalty relationships to the online logistics supply chain environment by examining potential website determinants of logistics customer service quality. A structural equation analysis of 373 online shopping transactions suggests that perceived quality of all logistics customer service activities (perceived cycle time, in‐stock availability, and customer responsiveness) varies inversely with: (1) perceived ease of use, and (2) content vividness of the website; and positively with product information content. However, only retailer customer responsiveness assessment was found to have any significant influence on consumer intended loyalty behavior in Internet‐enabled supplies chains.     

Agility index in the supply chain

To achieve a competitive edge in the rapidly changing business environment, companies must align with suppliers and customers to streamline operations, as well as working together to achieve a level of agility beyond individual companies. Consequently, agile supply chains are the dominant competitive vehicles. Embracing agile supply chain requires asking some important questions, namely: what exactly is agility and how can it be measured? Moreover, how can agility be effectively achieved and enhanced? Due to the ambiguity of agility assessment, most measures are described subjectively using linguistic terms. Thus, this study develops a fuzzy agility index (FAI) based on agility providers using fuzzy logic. The FAI comprises attribute’ ratings and corresponding weights, and is aggregated by a fuzzy weighted average. To illustrate the efficacy of the method, this study also evaluates the supply chain agility of a Taiwanese company. This evaluation demonstrates that the method can provide analysts with more informative and reliable information for decision.

对知识失业的经济学思考

“知识失业”是指受过高等教育的劳动力处于不得其用的一种状态。在我国经济发展的现阶段,“知识失业”现象也开始浮现。本文从经济学供给和需求的角度对我国的“知识失业”产生的原因进行了分析,并提出了有针对性的对策建议。     

Supply chain cost management and value-based pricing

Continued deflationary trends in many markets around the world are creating greater pressure for cost reduction in order that margins can be maintained. Customers and consumers are increasingly value driven and consequently less brand or supplier loyal. In this challenging world, there is a growing recognition that creative pricing strategies combined with effective supply chain management provide opportunities for significant cost reduction and increased profits. This paper presents evidence to support this viewpoint and suggests an approach to supply chain alignment that can enable cost reduction opportunities to be identified and higher profits to be achieved through collaborative strategies.     

Optimal requirement allocation among quantity-discount quoting suppliers

We consider a problem motivated by a central purchasing organization for a major office products distributor. This purchasing organization must source a quantity of a particular resale item from a set of capacitated suppliers. In our case each supplier offers an incremental quantity discount purchase price structure. The purchaser’s objective is to obtain a quantity of a required item at minimum cost. The resulting problem is one of allocating order quantities among an approved supply base and involves minimizing the sum of separable piecewise linear concave cost functions. We develop a branch and bound algorithm that arrives at an optimal solution by generating linear knapsack subproblems with feasible solutions to the original problem. This research was partially supported by a 2007 Summer Research Grant awarded to Asoo J. Vakharia.     

基于Meta分析的供应链网络嵌入性与协同创新绩效关系研究

供应链企业在合作中相互产生嵌入行为对高效整合链上资源以提高协同创新绩效至关重要,然而,两者之间的关系至今尚未形成一致性研究结论。本文利用Meta分析方法,以60篇相关文献、118个效应值、17911个独立样本作为研究对象,探究了网络嵌入性及各维度与协同创新绩效的整体效应,并运用亚组分析明晰了调节变量在两者关系中的调节作用。研究表明：网络嵌入性及其子维与协同创新绩效具有显著的正相关关系。另外,行业类型、区位因素、绩效类型及实证研究方法的不同均会导致研究结果不一致。本研究结论在一定程度上为网络嵌入性与协同创新绩效的关系研究提供了理论依据,同时也为供应链企业通过网络嵌入性提高创新能力提供了可资借鉴的参考思路。
