Response strategy to environment context factors using a lean and agile approach: Implications for firm performance

Based on the environment-strategy performance perspective and dynamic capabilities framework, we develop a theoretical model and hypotheses specifying how supply chain collaboration as a response to environment context factors – competitive intensity, supply uncertainty, technological turbulence and market turbulence, using a lean and agile strategy may influence firm performance. We test the model using partial least square structural equation modelling on data collected from a field survey with responses from 152 manufacturing firms representing a variety of industries. Empirical findings generally support the relationship between collaboration and firm performance using a lean and agile strategy. Also, for firms in industries that face environments characterised by high supply uncertainty and competitive intensity with, technological turbulence, the study finds evidence of a direct relationship between these environmental factors and supply chain collaboration. The findings provide an initial strategic response framework for appropriately aligning a lean and agile supply chain strategy through collaboration with environment context factors to achieve firm performance improvements.     

Competitive Capabilities among Manufacturing Plants in Developing,Emerging, and Industrialized Countries: A Comparative Analysis

Competitive capabilities have been defined as a plant's actual performance relative to its competitors, with the most commonly investigated capabilities being quality, delivery, flexibility, and cost. However, most research in this realm has investigated capabilities within developed countries, and neglected the context of developing and emerging nations, which are increasingly becoming viable economic entities in global supply chains in their own right. The present study fills this gap and carries out a comparative analysis of competitive capabilities among plants in developing, emerging, and industrialized countries. Basing our arguments on the resource‐based view of the firm, we suggest that the influence of competitive capabilities on each other varies among plants in differentially industrialized regions. Specifically, we suggest that, on average, competitive capabilities tend to influence each other to a greater degree in plants in emerging and developing countries compared to industrialized countries. Along similar lines, we suggest that the influence of the four competitive capabilities on performance improvement is manifested more strongly among plants in emerging and developing countries than among plants in industrialized nations. We investigate these contentions with data from 1,211 plants in 21 countries. The results are particularly important for decision makers as they decide on the increasingly global location of their manufacturing operations or the configuration of their global supply chains.     

Online coupon consumption problem

Nowadays, it is popular that the dealer makes profits by selling a kind of discount coupons, which can be used as money to purchase commodities with total cost less than or equal to the face value of the coupon. We can purchase a coupon at a price of 0<s≤1 times its face value and the number of potential purchasable coupons is a given integer l. The customer has the option to buy the goods by cash completely or by a discount coupon. However, each piece of goods can only use one coupon and the coupon used must have enough balance for the goods. The objective is to minimize the total cost for purchasing all the goods. In this paper, we reduce the problem to a special bin packing model. We consider the online problems for all 0<s≤1 and 1≤l≤∞. We present optimal online algorithms for all 0<s≤1 when l=∞ and l=1. For 2≤l<∞, we give both a lower bound and an algorithm, and show the algorithm is optimal for l=2.

基于企业属性的IT价值多维度研究

目前,业界对于IT为企业所带来的战略价值持有两种观点,一种观点认为,IT已经成为基础设施,是企业的一种纯技术工具,将不再为企业带来竞争优势,企业对于IT只需进行风险管理；另一种观点则认为IT仍然具有战略价值,对于提升企业竞争力仍具有推动作用。本文从组织管理的角度审视IT价值,结合企业特定的内部条件和外部环境探讨了IT带给企业的差异性,从行业、规模、组织结构、管理流程以及企业文化五个企业属性维度分析了IT对企业具有的不同战略价值,认为IT仍然是企业未来发展和提升竞争力的核心动力之一。     

公司战略定位与竞争环境适应性实证分析

WTO环境下,中国企业将与世界一流企业直接交锋。面对激烈的竞争环境,公司如何根据自身的特点,采取相应的竞争战略确定自己的战略性市场定位是急需解决的问题。论文利用我国企业调研的实际数据,对竞争战略定位与市场竞争环境的关系进行了实证分析。研究揭示公司战略的选择受竞争对手、消费者需求等市场环境因素影响;并且,战略类型的积极与否与行业市场环境的复杂性、资源的稀缺性等存在一定的相关性。     

On-line production order scheduling with preemption penalties

This paper studies the on-line production order scheduling problem where each preemption causes a penalty, and the objective is to maximize the net profit, i.e., the total weights of completed orders minus the total penalties caused by preemptions. Two greedy strategies are shown to be at best and -competitive respectively, where Δ is the ratio between the longest and shortest length of order. After that we mainly present an improved strategy, named WAL, which takes advantage of the knowledge of Δ and is proved to be -competitive for Δ > 9. Furthermore, two lower bounds for deterministic strategies, and 6.33, are given for the cases of nonuniform and uniform length respectively.

价格促销对品牌资产的影响:竞争反应的高地作用

在价格促销对品牌资产的影响方面,学者们并没有形成共识,原因之一是学者们忽视了竞争者的反应行为,本文旨在探讨竞争反应对这种影响关系的调节作用。本文通过2(品牌资产梯队)×8(竞争反应)的实验设计研究表明,对不同品牌资产梯队的品牌,价格促销对品牌资产的影响存在差异;竞争反应对这种影响关系具有调节作用;竞争对手的影响主要来自同梯队品牌,相反梯队品牌的影响不显著。本文对深入了解价格促销对品牌资产的影响具有重要意义。     

动态能力如何影响企业绩效——基于中国企业的实证研究

本研究以中国企业为样本对动态能力如何影响企业绩效的问题进行了分析和探讨。数据分析结果表明,战略过程对动态能力与企业绩效的正向作用关系具有明显的中介作用。但是,不同的动态能力维度对绩效的不同方面影响程度也不同,动态外部协调能力对企业绩效各个方面影响的显著程度在所有维度中最为突出,是企业在超竞争环境中树立竞争优势的关键。此外,动态能力构成维度间的路径关系表明,动态信息利用能力在企业动态适应外部环境变化过程中具有非常重要的节点作用,是企业培育动态能力路径的关键。     

Innovation timing advantages: From economic theory to strategic application

First and second mover theory, as developed in industrial organization economics, maintains that firms can gain competitive advantage by using optimal timing in the introduction of innovations. Because the industry is the unit of analysis, the theory does not provide specific guidance for individual firms. We analyze the underlying sources of first and second mover timing advantages and clarify several issues regarding the basic theory. We then identify a variety of factors at the industry, firm and product/service levels and develop propositions showing their relations to individual firms in their efforts to benefit from timing advantages. We discuss the link which these indicator factors provide between economic theory and strategic timing choices. Finally, we suggest directions for research which would assist firms and their managers in selecting and pursuing innovation timing strategies.     

Sorting and Decentralized Price Competition

We investigate the role of search frictions in markets with price competition and how it leads to sorting of heterogeneous agents. There are two aspects of value creation: the match value when two agents actually trade and the probability of trading governed by the search technology. We show that positive assortative matching obtains when complementarities in the former outweigh complementarities in the latter. This happens if and only if the match‐value function is root‐supermodular, that is, its nth root is supermodular, where n reflects the elasticity of substitution of the search technology. This condition is weaker than the condition required for positive assortative matching in markets with random search.
