供应链治理机制与供应链绩效之间的相互作用关系——基于信息共享的中介效应和信息技术水平的调节效应

本文构建起了供应链治理机制与供应链绩效之间的相互作用关系理论模型，并进而对信息共享在其中所起的中介效应及信息技术水平在其中所起着的调节效应进行剖析。以380份来自于供应链相关岗位的中高层管理人员及技术人员的问卷作为样本，利用结构方程模型对社会控制、正式控制、信息技术水平、信息共享及供应链绩效之间的相关关系进行实证研究。研究结果表明：（1）社会控制对信息共享及供应链绩效均产生正向影响，信息共享对供应链绩效也产生正向影响；而正式控制则对信息共享产生显著的负向作用关系，且其对供应链绩效的作用关系并不显著；（2）信息共享在社会控制和供应链绩效之间的作用关系中起着部分中介的作用，但其在正式控制-供应链绩效间的中介作用则并不显著；（3）信息技术水平对于社会控制-信息共享和正式控制-信息共享间的关系具有调节效应。     

The impact of supply chain management practices on competitive advantage and organizational performance

Effective supply chain management (SCM) has become a potentially valuable way of securing competitive advantage and improving organizational performance since competition is no longer between organizations, but among supply chains. This research conceptualizes and develops five dimensions of SCM practice (strategic supplier partnership, customer relationship, level of information sharing, quality of information sharing, and postponement) and tests the relationships between SCM practices, competitive advantage, and organizational performance. Data for the study were collected from 196 organizations and the relationships proposed in the framework were tested using structural equation modeling. The results indicate that higher levels of SCM practice can lead to enhanced competitive advantage and improved organizational performance. Also, competitive advantage can have a direct, positive impact on organizational performance.     

The impact of information sharing in supply chains on organisational performance: an empirical study

Information sharing has been cited as one of the major means to enhance supply chain performance. It allows companies to better coordinate their activities with their supply chain partners that lead to increased performance. This study conceptualises and assesses several factors that influence the degree of information sharing in supply chains, namely integrated information technologies, internal integration, information quality and costs–benefits sharing. The relationship between the degree of information sharing and organisational performance is then tested. Data from 150 manufacturing companies were collected and proposed relationships are examined using structural equation modelling. The results show that integrated information technologies and information quality have positive influence on the intensity of information sharing. However, internal integration and costs–benefits sharing do not relate to the intensity of information sharing. This study finds that information sharing does not directly relate to organisational performance. Its relationship is mediated by collaboration practices with supply chain partners. This suggests that information sharing is essential but insufficient by itself to bring significant performance improvements.     

供应商机会主义行为对信息共享与运营绩效的影响

在交易成本理论基础上,构建供应商机会主义行为、信息共享与运营绩效之间关系的理论模型。以广东省珠三角地区189家制造企业为研究对象,利用结构方程模型对供应商机会主义行为、信息共享与运营绩效的关系进行实证研究。将信息共享划分为信息共享内容和信息共享质量两个维度,将运营绩效划分为速度、服务和财务3个维度。研究结果表明,在供应商机会主义行为与信息共享的关系层面,供应商机会主义行为对信息共享内容和信息共享质量均有显著的负向影响;在信息共享与运营绩效的关系层面,信息共享内容和信息共享质量均对运营绩效有显著的正向影响;而供应商机会主义行为对运营绩效有显著的负向影响。根据上述实证研究结论给出供应链企业和政府的相关管理启示。     

QoS in the internal supply chain: the next lever of competitive advantage and organisational performance

This article presents a research that examines the relationship of quality of service (QoS) and organisational performance in a manufacturing setting. There are few empirical studies that measure QoS in the manufacturing supply chain. A model linking QoS with organisational performance through intermediate variables of satisfaction, loyalty and competitive advantage is introduced and tested in the internal supply chain of three automotive organisations. The research design for this article includes a combination of literature review, exploratory interviews with scholars and practitioners, and a survey of 156 practitioners in three automotive companies in North India. Structural equation modelling has been used for data analysis. This research comes out with four factor scale for internal service quality and six-factor scale for external service quality. The research revealed that employee-driven QoS is a source of value addition that is positively linked with the organisational performance. This study would be of interest to manufacturing industry practitioners interested in internal and external service quality improvements. Future researchers could validate this scale, and empirically test the proposed model.     

基于个性化需求的产品竞争供应链结构选择

基于"制销分离"与"定制一体"两种结构选择,构建个性化产品供应链处于非竞争与竞争环境下的博弈模型,在引入一个实际案例的基础上,运用算例仿真比较分析两种运营模式下的供应链运作策略和盈利差异。结果显示：与制销分离结构相比,个性化产品供应链选择定制一体结构,有利于匹配产品个性化制造、提升产品个性化水平和市场需求、增加供应链的期望收益;个性化产品供应链选择制销分离结构时,适度的批发价格激励能够提升产品个性化水平、更好满足消费者个性化需求、改善供应链的运营绩效,分销商适度让利加大批发价格激励力度可显著促进产品个性化制造互动、提升产品个性化水平;竞争将消减个性化产品供应链的运营绩效,但选择定制一体结构可显著提升竞争力。     

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.     

Supply Chain Management: Relationships, Chains and Networks

The term supply chain management is used to represent a variety of different meanings, some related to management processes, others to structural organization of businesses. This paper identifies and discusses various definitions of supply chain management, summarizes the associated bodies of knowledge and connects them using a systems approach. Systems levels of supply chain management are identified as the internal supply chain, the dyadic relationship, the external supply chain and the inter-business network.
Empirical research on behavioural aspects of relationships, chains and networks in the European automotive aftermarket is discussed, identifying gaps in perceptions of requirements and performance held by customers and suppliers in the areas of quality, delivery, service, range and price. A combination of qualitative and quantitative analysis demonstrates substantial differences between approaches to supply chain management, though performance in relationships, chains and networks in the territories examined does not differ significantly.
Customer dissatisfaction in relationships is shown to increase upstream in the supply chains examined, extending the applicability of the industrial dynamics 'Forrester effect' to softer, behavioural aspects of performance. Conclusions are drawn supporting the suggestions of operations strategists that position in the supply chain is an important strategic variable which, to date, have not been comprehensively proven empirically.     

供应链中纵向信息获取和横向信息共享策略研究

研究由一个制造商和两个零售商组成的二级供应链中,零售商之间的横向信息共享策略和制造商的信息获取以及最优定价问题。在模型中,制造商同时为两家零售商提供等价商品,零售商向消费者销售商品且进行价格竞争。以Bertrand博弈为研究手段,求解了零售商的均衡销售价格、订货量决策和信息共享策略,制造商的最大利润和最优批发价格,以及供应链利润。分析比较了在制造商不同的信息获取策略下,零售商、制造商和供应链的利润。研究表明,零售商之间完全信息共享始终为占优策略。但制造商获取下游信息时会使得自身利润增加,零售商利润减少,因此零售商不会主动把信息共享给制造商。考虑到下游的边界均衡解,供应链的利润变化还与市场的不确定性和产品的替代性有关。当产品替代性较高或产品替代率较低且市场的不确定性处于中间水平时,制造商获取信息后供应链利润增加,此时制造商可以用部分增加的利润成功购买零售商信息。该模型为上游制造商提供了最优定价和信息获取策略,也为下游零售商提供了求解自身最优销售价格、订货量和信息共享决策的方法。     

Causal Linkages in Supply Chain Management: An Exploratory Study of North American Manufacturing Firms

In this paper we investigate the key causal linkages in supply chain management. We propose a conceptual framework and test this framework on data from 215 North American manufacturing firms using structural equation modeling techniques. Three major research issues are addressed in this study: Do sourcing decisions affect the degree to which firms achieve manufacturing goals of cost, flexibility, dependability, and quality? Does the degree of manufacturing goal achievement lead to higher customer responsiveness? Does the degree of manufacturing goal achievement lead to higher internal manufacturing performance? The study examines the relationship among sourcing decisions, manufacturing goals, customer responsiveness, and manufacturing performance. The results support the notion that an integrated supply chain involves aligning sourcing decisions to achieve manufacturing goals that are set to respond favorably to the needs of customers.     

供应链伙伴间信息共享对运营绩效的间接作用机理研究——以关系资本为中间变量

构建了以关系资本中的信任及关系承诺等维度为中间变量的供应链伙伴间信息共享对企业运营绩效间接作用机理的理论模型。以广东省珠三角地区141家制造企业为调查对象,利用结构方程模型对供应链伙伴间信息共享、关系资本(信任与关系承诺)与运营绩效之间的关系进行实证研究。研究结果发现供应链伙伴间信息共享与运营绩效之间存在两条间接作用路径,即"信息共享→信任→运营绩效"和"信息共享→信任→关系承诺→运营绩效",这表明供应链伙伴间信息共享的确可以以关系资本中的信任与关系承诺等维度为中间变量而间接地作用于企业运营绩效。     

需求不确定下制造商服务投入影响销售的供应链信息共享与激励

针对需求不确定环境下制造商既提供产品也提供相关服务时产品服务供应链中的信息共享与激励问题,考虑零售商拥有需求预测信息且可选择共享任意水平的信息量,通过构建不完全信息下的动态博弈模型,分析了零售商信息共享水平、制造商服务效率以及消费者服务敏感性对服务价值和信息共享价值的影响,并提出了基于两部补偿契约的信息共享激励策略。研究表明：需求信息共享能够有效提升整个供应链的服务价值;当制造商服务效率或者消费者服务敏感性较高时,信息共享的服务改善效应将占优于其双边际效应,零售商会自愿共享全部需求信息并达到供应链"双赢";而当制造商服务效率或者消费者服务敏感性较低时,采用两部补偿激励契约可实现产品服务供应链中的完全信息共享,并且契约实施难度会随着零售商需求预测精度、制造商服务效率以及消费者服务敏感性的提高而降低。     

Leveraging Supply Chain Integration through Planning Comprehensiveness: An Organizational Information Processing Theory Perspective

This study extends prior research on supply chain planning and integration by examining the underlying capabilities by which firms exploit the information they gain from integration activities. We use organizational information processing theory (OIPT) to develop hypotheses that identify the comprehensiveness of an organization's supply chain planning capabilities as an important mediator in the relationship between its supply chain integration activities and its operational performance. Further, our interpretation of OIPT suggests that an organization's usage of technology‐enabled supply chain management systems (SCMS) moderates these effects. Using survey data from 445 global firms, we estimate the corresponding moderated‐mediation structural model. The results indicate that usage of SCMS enables organizations to better utilize the information they gain from external integration efforts (relationships with customers and suppliers), thus improving the comprehensiveness of their supply chain planning capabilities. In contrast, the use of SCMS appears to be a partial substitute for internal integration as a driver of planning comprehensiveness. Most importantly, the results suggest that planning comprehensiveness is a significant generative means by which integration and technology investments produce superior operational performance. These findings provide a richer and more theoretically grounded explanation of relationships between supply chain integration, supply chain planning, and operational performance.     

The Roles of Supply Chain Intelligence and Adaptability in New Product Launch Success

Many new product introductions continue to be unsuccessful, and while researchers have studied product development processes, relatively few studies directly address new product launch. We do so in the present research and posit that supply chain intelligence, defined as technological and competitive knowledge sourced and integrated from suppliers, customers, and competitors, plays an important role in explaining new product launch success. We further employ the knowledge‐based view to theorize that both supply chain adaptability and product innovation capability act as important mediators of the effects of supply chain intelligence on new product launch success and firm financial performance. While the former capability refers to a firm's ability to quickly adjust its supply chain to react to market and product design changes, the latter refers to the firm's proficiency in developing innovative new products. We test hypothesized relationships among these factors utilizing data collected in a survey of 229 U.S. manufacturing firms. Results point to the central role of supply chain adaptability in capturing the benefits of supplier technological intelligence for enhanced product innovation capability, new product launch success, and firm financial performance. In contrast, product innovation capability serves as the generative means by which customer and competitor intelligence is translated into more successful new product launches, which, in turn, produce superior firm financial performance. Overall, these findings contribute to a better understanding of factors that can explain why certain product launches are more successful than others, and offer practical insights for appropriate investments in the development of related knowledge resources.     

基于策略性竞争博弈的供应链信息共享策略

在供应链成员的市场信息以及成本非对称的情形下,讨论两个终端企业（一个自产自销,一个从上游批发产品）,在供应链中信息共享策略的方案,包括：信息优势企业如何根据市场需求情况确定是否信息共享（若是,则如何共享）;信息劣势企业如何根据对方透露出的市场信息来决策订货量;上游供应链如何决策批发价,从而控制整个供应链的博弈态势,使下游销售商在竞争中更为主动。经过研究发现,低市场类型时,自产自销商乐于共享信息,使竞争对手摄于低迷的市场状况从而降低订货量;在高市场类型且市场波动较小时自产自销商依然选择共享,在乐观的市场条件下表明自己的竞争优势,从而一定程度上威摄入侵者;而市场波动较大时,由于信息共享的额外收益不足以抵消信息共享需付出的额外成本,从而选择不共享信息。     

制造业供应链伙伴间态度性承诺对供应链脆弱性作用机制

构建供应链伙伴间态度性承诺对供应链脆弱性作用的理论框架,以252家中小型制造业企业为研究对象,基于enter层次回归分析法检验供应链动态能力在供应链伙伴间态度性承诺与供应链脆弱性关系间的中介作用以及供应链外部社会资本在供应链伙伴间态度性承诺与供应链脆弱性关系间的调节作用;运用多重中介效应检验模型验证供应链动态能力的3个维度同时作为供应链伙伴间态度性承诺与供应链脆弱性关系间中介变量的合理性。研究结果表明,供应链伙伴间忠诚性承诺显著降低供应链脆弱性,供应链伙伴间计算性承诺与供应链脆弱性呈U形关系,供应链动态能力在供应链伙伴间态度性承诺与供应链脆弱性关系间发挥部分中介作用,内外互动强度和外部网络密度分别显著调节供应链伙伴间态度性承诺与供应链脆弱性的关系,内外信任程度和内外共同语言在供应链伙伴间态度性承诺与供应链脆弱性的关系间发挥不显著的调节作用。     

存在竞争性制造商的集团采购供应链需求预测信息的共享与激励

针对两个竞争性制造商通过集团采购组织(GPO)采购部件时,是否向GPO共享需求预测信息的激励问题,考虑各制造商拥有有限信息、共享部分信息、基于产量竞争的情形,通过建立博弈模型,分析了竞争强度、信息精度和市场波动对信息共享价值的影响,进而提出了信息共享激励策略。研究表明:信息共享能够协调制造商间的竞争,当且仅当竞争强度超过某阈值时,信息共享能够增加供应链的系统预期利润,此时,用两部制补偿协议可激励制造商完全共享信息;当竞争强度和市场波动均较大时,通过信息共享激励,分散式决策能够实现比集中式决策更大的系统预期利润。最后,通过算例对研究结论进行了直观考察和说明。     

Japanese Supply Chain Relationships in Recession

The remarkable nature of Japan’s supply chain relationships has been identified as a significant factor in its industrial success, especially in the automotive and electronics sectors. Yet, Japanese companies do not recognise the term ‘supply chain management’. For four decades Japan’s industrial giants developed sourcing strategies based on highly-pressured, customer-dominated supply relationships in which sub-contractors enjoyed the benefits of the success of their customers at the expense of yielding their autonomy. In 1991, the Japanese economy plunged into deep recession and has yet to recover. Large corporations now appear vulnerable and almost all Japan’s banks are technically insolvent. This article explains the ways in which recession has affected the supply chain relationships in Japan and the domestic and international sourcing strategies that shape them. Japanese industrial customers are now putting increased pressure on their suppliers to provide technical solutions and to develop links with other customers for the first time. The sub-structures of the keiretsu appear to be giving way to open competition with ‘parent’ firms selling equity in subsidiaries. Profound changes appear to be underway in Japanese industrial sourcing strategies—suppliers can no longer rely on retaining business simply by obedience and hard work. Instead, they face an open, fiercely competitive environment—at home and abroad. In this new order, Japanese suppliers are developing new competitive technical and commercial capabilities, enabling their Japanese industrial customers to concentrate on real-time, market-driven configuration of products, without needing to hold stocks in their supply chains and distribution channels. Meanwhile, Japan is seeking to re-establish its position of leading player in East Asia.     

A hybrid solution to collaborative decision-making in a decentralized supply-chain

This paper considers a decentralized supply chain, where multiple independent manufacturing facilities manage some capital-intensive equipments or resources shared among them. In particular, these manufacturing facilities operate somewhat in isolation to serve their own customers, but coordinate closely with each other to ensure the shared resources are effectively utilized. Such cross-facility capacity management problems are common in high-tech industries, they are typical examples of collaborative decision-making in supply chain integration, and are critical to create a competitive edge in a more interconnected business environment. In this paper, a hybrid algorithm that integrates Lagrangian relaxation and immunity-inspired coordination scheme, known as LR-ICI, is proposed and investigated by extensive numerical experiments, and is shown to be competitive compared to similar algorithms.
