Effects of Supply Chain Management on Tomato Export in Iran: Application of Structural Equation Modeling

Although Iran is one of the top 10 countries in the world that produce tomatoes, the level that they are exported into the global market is low. This issue may have resulted from a major problem within tomatoes’ supply chain management. This paper aims to develop an empirical model of the supply chain management (SCM) of tomato companies. Throughout the reviewed literature, a SCM construct with different six indicators has been developed, including information sharing, long-term relationship, cooperation, quality, flexibility, and delivery. In this study, the influence of the SCM components on tomato export was identified through the use of empirical data that were collected from 20 different tomato companies in Northeast Iran. Using structural equation modeling, the major elements of SCM were found to have significant impacts on the export of tomatoes. The results also showed that information sharing, cooperation, flexibility, quality, and delivery had significant positive effects on the export of tomatoes.

Responsible supply chain management in the Asian context: the effects on relationship commitment and supplier performance

Responsible supply chain management (SCM) in the era of expanding global sourcing can play a critical role in diffusing corporate responsible practices throughout the emerging Asian economies. Thus, this paper aims to examine how responsible SCM can contribute to supplier performance, including environmental, social and operational performances through the improvement of relationship commitment in the Asian context. The hypotheses of this study were tested with the data from 187 South Korean suppliers and 193 Vietnamese suppliers. The paper finds that responsible SCM enhances relationship commitment as well as improves the sustainability performance of suppliers in Asian countries. Relationship commitment plays a critical and mediating role in the relationships between responsible SCM and environmental, social and operational performances. This study also finds that there is a contextual difference between South Korea and Vietnam. The findings of this paper provide implications for supply chain members to integrate environmental and social issues into their SCM practices so as to foster stronger sustainability performance in the global supply chain.     

Retail supply chain management practices in India: A business intelligence perspective

The study surveyed executives of a major food retailer in India and explored their perspectives on supply chain management practices, competitive advantage and firm performance; to assess the importance accorded to application of business intelligence (BI) in their operations. Nine dimensions for SCM practices and four dimensions for competitive advantage are identified which are found to strongly relate to each other. The dimensions of SCM also strongly relate to firm performance. Though information sharing with suppliers and their inclusion in strategic decision-making emerge as key dimensions of SCM, their impact on competitive advantage is perceived to be insignificant by retailers.     

Exploiting Mobile Technology for Achieving Supply Chain Integration in Indian Retail

For decades supply chain coordination has been subject to research interest, and technology has been seen as an agent that accelerates this process. In developing countries, with far-flung markets and unorganized distribution networks, using technology for improving supply chain performances and accessing information is not an easy task. The research was directed to understand if mobile technology is being used by downstream supply chain partners for information sharing and thus improving supply chain performances. Findings suggest that supply chain integration with suppliers and customers is done through extensive use of mobile networks.     

Lean supply: the design and cost reduction dimensions

The objective of this paper is to determine whether the principles of the lean supply model are currently present between an OEM and its key suppliers in the electronics industry. The research focuses on two key dimensions of lean supply – supplier involvement in customer design activities and joint buyer–supplier cost reduction. Although the findings have indicated the presence of some of the principles associated with lean supply in areas such as higher levels of customer and supplier integration in the new product development process and high levels of information exchange in the supply chain, total ‘leanness’ along these dimensions is not currently present. In fact, the research has revealed that considerable barriers currently exist to meeting the requirement of equality between partners and the mutual sharing of benefits. Evidence found here has shown that the majority of benefits accrued from the relationship were obtained by the customer.     

Ethical Screening and Financial Performance: The Case of Islamic Equity Funds

Poor working conditions remain a serious problem in supplier facilities in developing countries. While previous research has explored this from the developed buyers’ side, we examine this phenomenon from the perspective of developing countries’ suppliers and subcontractors. Utilizing qualitative data from a major knitwear exporting cluster in India and a stakeholder management lens, we develop a framework that shows how the assumptions of conventional, buyer-driven voluntary governance break down in the dilution of buyer power and in the web of factors rooted in suppliers’ traditions, beliefs, local demands and resource dependency. We reveal out how success in governing collaborative global supply chains often falls short within the subcontracting stage, where a stakeholder management mindset is elusive to most participants. We suggest that success in governing collaborative global supply chains is dependent on concepts of stakeholder utility and the presence of shared value that is often at odds with the realities of power, information asymmetry and compliance/reward systems inherent in the non-market coordination of global supply chains. Our findings offer important insights for delineating the concepts of value creation from CSR concepts and practices, and for modifying the basic assumptions of conventional supply chain governance.     

Supplier Role Conflict: An Investigation of Its Relational Implications and Impact on Supplier Accommodation

Existing research on supply chain relationships suggests that one of the underlying tensions between supply chain partners is that of opposing perspectives and goals in the customer?supplier relationship. In today's business world with requirements in constant flux, suppliers are often asked to accommodate “special” requests made by their customers, not part of the contractual agreement. Suppliers frequently fill requests to protect the relationship with the customer, even if they fall outside of what they consider their role as a supplier. Issues of supplier role conflict emerge when customers and suppliers have different views of what the supplier's role should entail. There is little research examining the potential for supplier role conflict in supply chains. Specifically, this research draws on literature from multiple disciplines to consider supplier role conflict that may stem from accommodation and the impact of this role conflict and supplier accommodation on the supply chain relationship and future accommodation behavior. Hypotheses are tested using two scenario‐based experiments. Results suggest that supplier adaptation and flexibility both have positive relational effects. If suppliers perceive accommodation requests as outside of their contracted role, supplier role conflict can have detrimental effects on the supplier's relationship perceptions and their willingness for future accommodation.     

VMI模式下信息共享对违约风险的防范和控制

供应商管理库存（Vender Managed Inventory,VMI）是21世纪前沿的供应链管理模式,VMI对供应链的新形式供应的形成和发展都产生了影响。但由于我国信息化起步晚,使得很多企业在实施VMI模式时仍存在不同程度的风险。为了实现对VMI违约风险防范和控制的有效性,供应链上的各个企业越来越注重供应链成员之间的协调关系,而这就需要以供应链上各个节点的成员企业进行高质量的信息传递和及时完整的信息共享为基础来建立和完善整个VMI系统。研究供应商实施VMI的过程中所面临的违约风险,重点分析VMI模式下信息共享对违约风险防范控制作用,可有效地实现信息共享以降低VMI模式下的违约风险。     

A Virtue-Ethics Analysis of Supply Chain Collaboration

Technological advancements in information systems over the past few decades have enabled firms to work with the major suppliers and customers in their supply chain in order to improve the performance of the entire channel. Tremendous benefits for all parties can be realized by sharing information and coordinating operations to reduce inventory requirements, improve quality, and increase customer satisfaction; but the companies must collaborate effectively to bring these gains to fruition. We consider two alternative methods of managing these interfirm supply chain relationships in this article. The first, which we have named “dictatorial collaboration,” occurs when a dominant supply chain entity assumes control of the channel and forces the other firms to follow its edicts. We compare and contrast this method with “sustainable collaboration,” in which the parties share resources and engage in joint problem solving to improve the performance of the system as a whole. We use a virtue ethics lens to describe these methods of relationship management to suggest that sustainable collaboration is preferable to dictatorial collaboration both operationally and ethically in the long run.

The Impact of Key Retail Accounts on Supplier Performance: A Collaborative Perspective of Resource Dependency Theory

Existing literature suggests that the increasing concentration in the retail industry is allowing powerful retailers to exploit their weaker suppliers, which causes the suppliers’ performance to suffer. This study takes a collaborative perspective of resource dependency theory and suggests that when suppliers engage in supply chain relationships with key retail account (KRA) customers, their performance may improve, depending on the varying levels of the supplier's and KRAs’ market shares. The empirical analysis of data from two large retailers, Wal-Mart and Target, and a broad cross-section of their suppliers provides ample support for most of the hypotheses set forth in this paper: Suppliers that depend on KRAs for a significant share of their total revenues relinquish some of their leverage in the marketplace, but as the KRAs gain market share, their suppliers’ performance tends to increase. Cumulatively, these results provide evidence of collaborative supplier–KRA relationships, such that a supplier's dependency on KRAs may positively affect supplier performance. This finding supports a more positive, symbiotic view of dependency, resulting in important implications for key account management, supply chain management, and retail research and practice.     

Understanding the Development of IOS-Based Trading Partner Relationships: A Structural Model with Empirical Validation

This study develops a research model that explains the interorganizational system (IOS) network development process in the buyer-supplier relationship. Particular attention is paid to the antecedents and consequences of two types of influence strategies— exercising power and offering IOS support—that a buyer firm often uses in increasing IOS usage with its suppliers. The research model is empirically tested with data obtained through a field survey from a sample of 233 suppliers, each exchanging electronic data interchange (EDI) documents with a nationally known retailing buyer in the United States. We find that the buyer's decision to offer EDI-related support to a supplier is negatively associated with the transaction volume with the supplier but positively with the supplier's IT capabilities as well as the supplier's transaction-specific investments made toward the relationship with the buyer. On the other hand, the buyer's decision to exercise power to a supplier is found to be negatively associated with the transaction volume between the trading partners. Our findings also indicate that offering EDI support, rather than exercising power, is more effectual in inducing greater EDI usage between the trading partners. Finally, the buyer's EDI support is found to be positively associated with suppliers' perceived benefits of using EDI in the relationship that, in turn contributes to more voluntary use of EDI with the buyer.

The Value of Information Integration in Meeting Delivery Dates

In this article, we consider the value of shared information within a business network. To make the problem concrete, we focus on a specific operational problem: How the final supplier to the customer determines promised delivery dates. In a traditional supply chain, the final supplier has little or no information on the delivery performance of intermediate suppliers and thus, has limited information with which to set delivery dates. On the other hand, in an information-integrated business network, the final supplier's enterprise resource planning (ERP) system can interact with all the intermediate suppliers' ERP systems to determine exactly how far ahead or behind schedule the network is in meeting the needs of a specific customer. This information should improve the final supplier's ability to set realistic delivery dates. We attempt to quantify the value of this information and determine precisely why it is valuable so that management can best exploit information integration.

We use a modeling approach in this research, beginning with simple analytic models and progressing to more realistic simulation models. Our analytic model establishes an important principle: Information integration not only significantly improves the average on-time delivery performance of a business network, but also dramatically improves its worst-case performance. Because customer dissatisfaction is generally associated with worst-case performance, information integration may be highly beneficial even if its effect on average on-time delivery is small. Simulation models allow us to compare the performance of more realistic business networks. These models suggest, for example, that the value of information integration is dependent on both the structure of the network itself (whether serial or arborescent) and on the typical customer order date in the production cycle. These insights allow us to begin to identify the types of business networks in which information integration will have the highest value.     

RFID Applications for Integrating and Informationalizing the Supply Chain of Foodservice Operators

Abstract

By enabling easier and real-time information sharing among supply chain partners, Internet applications foster and support new forms of collaborative supply chain management (SCM) practices within the foodservice sector. Advances in Radio Frequency Identification (RFID) technologies extend such collaborative SCM practices by increasingly integrating and synchronizing demand and supply chains. The objective of this paper is to investigate and analyze how RFID technologies can seamlessly tie customer interactions with the food supply chain and revolutionize the accuracy, efficiency, personalization-interaction, and security of foodservice marketing, production, and distribution simultaneously. To achieve this, the paper discusses the RFID implementation issues, practices, and benefits within the foodservice sector. The food industry's perspectives on the adoption and benefits of RFID developments are reported by discussing the results of a reality-check study conducted in the Greek foodservice sector.     

Small and Medium‐Sized Enterprises' Collaborative Buyer–Supplier Relationships: Boundary Spanning Individual Perspectives

Boundary‐spanning individuals (BSIs) play a critical role in supply chain management, especially in small and medium‐sized enterprises (SMEs) where interactions with buyers and suppliers can depend heavily on just a few individuals. This study, utilizing data from Korean manufacturing‐sector SMEs, explores whether cooperative social value orientations of SMEs' BSIs influence the effects of collaborative buyer‐supplier initiatives. The results suggested that the performance implication of decision‐sharing initiative increases when BSIs have a high level of cooperative social value orientation. However, it also negatively moderates the relationship between risk/benefit sharing (involving financial losses or gains) and performance suggesting possible negative side effects. However, we found that such orientation also negatively moderates the relationship between risk/benefit sharing (involving direct financial losses or gains) and relationship performance suggesting possible negative side effects.

Supply chain consortia: the rise of transcendental buyer–supplier relationships

A theoretical, cross-disciplinary model for cooperative buyer–supplier relationships is proposed which integrates information obtained from prior research on organizational culture and transaction cost analysis (TCA). The authors describe key elements of TCA and review the three types of transaction governance structures commonly used to explain relationships within an organization. The authors extend this by applying structure type to buyer–supplier relationships. The researchers propose several types of interorganizational relationships and conclude with an in-depth discussion of a successful supply chain consortium used by Boeing Aircraft Company and several key suppliers.     

Why do buyers share knowledge with suppliers in new product development? current and alternative supplier antecedents

Purpose: Interfirm knowledge sharing has been well recognized to activate the performance and competitiveness improvement of the firms. Previous research has discussed the impacts of current suppliers on buyer–supplier knowledge sharing, but does not explain how this influence occurs. This study aims to disclose the mechanism by which both current and competing suppliers impact buyer–supplier knowledge sharing in buyers’ new product development activities.

Methodology/approach: This study proposed a conceptual model based on relational exchange theory and developed eight hypotheses. Questionnaire survey was used to collect empirical data from R&D staff of Taiwanese electronics firms. This study distributed 1,475 questionnaires and received 246 eligible questionnaires. Structural equation modeling was used to test and verify appropriateness of the proposed model.

Findings: The findings show that current supplier asset specificity positively and directly influences buyer–supplier knowledge sharing in new product development. The current supplier asset specificity also has indirect positive influence on buyer–supplier knowledge sharing in new product development via the mediating effects of buyer trust, satisfaction, and commitment. However, the attractiveness of alternative suppliers only indirectly and negatively affects buyer–supplier knowledge sharing via the mediating effects of buyer trust, satisfaction, and commitment.

Research limitations/implications: This study surveyed the firms in Taiwanese electronics industry. Nevertheless, new product development activities are executed by electronics firms in numerous countries and firms in various industries. For validating the generalization of this study’s results, future research can investigate firms in other industries and countries to verify the proposed model and hypotheses.

Practical implications: Current suppliers’ asset specificity is found to exert more influence on buyer–supplier knowledge sharing than alternative attractiveness. The findings imply that current suppliers should focus on investing specific assets for buyers other than stress the attractiveness and threat of competing suppliers.

Originality/value/contribution: This study initiates to approach the antecedents and influence mechanism of current buyer–supplier knowledge sharing via both perspectives of current and competing suppliers.
