Market Model-Based Channel Selection in B2B E-Commerce: Exploring a Buyer's Adoption Decisions

Companies that seek to exploit the cost advantages of business-to-business (B2B) e-Commerce face a variety of strategic options. By analyzing the demand and cost functions for sellers, intermediaries, and buyers, this research develops an economic framework that clarifies the relative advantages of four common B2B e-Commerce channels: private exchange, web-based procurement, public aggregation, and public exchange. This research focuses on addressing two important questions: (1) How does a buyer select a suitable B2B e-Commerce channel (or an e-Marketplace structure) given a variety of market conditions, different levels of product substitution, and a range of purchasing patterns? (2) How does a buyer successfully manage a B2B e-Commerce channel for gaining the highest transaction-level buyer surplus? The analytic and numeric results of our study show that a company's product offerings, the market conditions it faces, and the purchase patterns it implements are all important determinants in the selection of B2B e-Commerce setting. For custom products, private networks (such as the private exchange or web-based procurement models) are more attractive than the public aggregation or exchange models. However, taking market conditions and purchasing behavior into consideration, the web-based procurement model is more suitable for spot purchasing, while the public exchange model is more suitable for systematic purchasing and fragmented markets. On the other hand, the aggregation model is preferable in concentrated markets while the exchange model is more suitable in fragmented markets. These results provide important implications for industrial development of B2B e-Commerce.     

The Survival of Internet-Based B2B Exchanges

Abstract

Researchers have suggested that businesses are undergoing a paradigm shift due to the emergence of the Internet. In the business-to-business arena, fundamental process changes are taking place due to the emergence of Internet-based B2B exchanges. Three types of B2B exchanges have emerged-independent or third party industry specific B2B exchanges, buyer or supplier coalition-based B2B exchanges, and corporate B2B exchanges. While the costs savings associated with Internet-based B2B exchanges are well understood, this paper highlights the critical role that relationships will play in the success or failure of B2B exchanges. Using transactional cost framework, we analyze the various types of Internet-based B2B exchanges and conclude that corporate exchanges have a comparative advantage over open market exchanges, as well as over buyer or supplier coalition-based exchanges. It is our expectation that this paper will serve as a catalyst for future research in this area.     

Drivers of Adoption and Continued Use of E-Procurement Systems: Empirical Evidence from China

ABSTRACT

This article develops and empirically tests a research framework that models the role of technological, organizational, and environmental factors in organizational intention toward using e-procurement systems. The partial least square analysis of survey data from 211 firms in China demonstrates that technological factors including perceived efficiency benefits and perceived ease, organizational factors including business to business commerce expertise, information sharing culture, and top management support, and an environmental factor, business partner pressure, shape in different ways organizational intention to adopt and to continue with e-procurement. The findings of the study not only offer valuable insights for stimulating the diffusion of e-procurement systems but also provide important guidance to systems vendors in strategizing their marketing campaigns and focusing limited resources on relevant strategic components.     

Buyer profiles: an empirical investigation of changing organizational requirements

Many authors have commented that the profile of the industrial buyer must change if purchasing is to adapt the increasingly dynamic and complex contexts in which firms operate. This exploratory, empirical study examined and compared the trait profiles of current top performers and of ‘ideal’ buyers for the future. This approach links buyer traits with perceived managerial satisfaction with role performance. Based on cluster analysis, we present a taxonomy of five ‘ideal’ types of buyer. We propose that future research should seek to match the identified trait clusters with a typology of purchasing contexts.     

Factors affecting the breadth and depth of e-procurement use in small and medium enterprises

Organizations differ in the range of e-procurement functionalities they use (breadth of use) and in how much they rely on e-procurement (depth of use). Nonetheless, factors affecting the breadth and the depth of e-procurement use have never been studied in a single context. Therefore, it is unclear whether the differences between the effects discovered in past studies are due to the difference between the breadth and the depth of use, or to the difference between contexts. We test the effects of factors potentially affecting the breadth and the depth of e-procurement use in a single context, using data from 151 small and medium enterprises (SMEs) in the manufacturing sector in New Zealand. The results indicate that the breadth and the depth of use of e-procurement in business organizations are influenced by different factors. Perceived relative advantage of using e-procurement, plus external pressure from suppliers and competitors to use e-procurement, result in the use of a broader range of e-procurement functionalities – in a greater breadth of e-procurement use. However, the extent of an organization’s reliance on e-procurement in organizational purchasing (i.e., depth of e-procurement use) is driven by compatibility of e-procurement with organizational values, practices, technology infrastructure, and strategy. Arguing that in order to benefit fully from e-procurement, an organization needs to integrate it deeply into its operations, we conclude that managers evaluating new e-procurement technologies should consider their compatibility with organizational norms and practices.     

Web Services for Negotiation and Bargaining in Electronic Markets: Design Requirements, Proof-of-Concepts, and Potential Applications to e-Procurement

Information Systems researchers continue to develop Web services hoping that, in a near future, these services will be widely offered in the e-marketplace, using a Web-based protocol that is universally adopted for posting, locating and invoking available services. Posting services does not, however, necessarily lead to market transactions, and a number of brokering activities are needed to facilitate trade. These include, but are not limited to, service discovery and ranking, price negotiation and contract preparation. We propose a set of Web services that support the process of negotiation and bargaining to facilitate the matching of supply and demand of Web services. As a market broker, these web services would help (a) discover the supply/demand of web services in e-marketplaces; (b) find the most appropriate available service for a specific request; (c) facilitate services be modified if needed to satisfy user's needs; (d) arbitrate the pricing mechanism with the recourse to bargaining whenever necessary; and (e) generate a contract. As a proof of concept, we illustrate the potential use of Web services for negotiation and bargaining in e-procurement.     

从BCG矩阵看采购项目定位模型

回顾了从BCG矩阵到GE矩阵的发展,GE矩阵由于基本假设和很多局限性都和BCG矩阵相同,最大的改善就在于用了更多的指标来衡量两个维度。也正是由于GE矩阵使用多个因素,可以通过增减某些因素或改变它们的重点所在,很容易地使GE矩阵适应经理的具体意向或某产业特殊性的要求。市场和采购的天然联系,因此回顾了采购项目定位模型的发展,发现原有模型在因素选择和量化、细化方面可以进一步探究,并提出了采购项目在模型内的移动性问题和买卖双方关系问题。进而给出建议的研究方向。     

Modeling e-Negotiation Processes for a Service Oriented Architecture

Most of today's e-marketplaces support a single negotiation protocol. The protocol is usually built into the e-marketplace infrastructure, therefore if a new one is introduced then a time consuming and complex process of implementing it takes place. Moreover, participants in the e-marketplace need to adapt their interfaces to the new protocol, especially if they use automated tools to interact with the e-marketplace. This paper reports on a model-driven approach and a framework for rapid and user-friendly development of configurable service oriented e-negotiation systems. We believe that a formal specification of negotiation protocols and their separation from the market infrastructure that implements them is a step towards configurable e-negotiation systems. The protocols are graphically designed for the e-marketplace then mapped into web service orchestrations. Participants use automated negotiation systems to interact with the e-marketplace. These systems are generated based on the negotiation protocol implemented on the e-marketplace. A declarative language is used to specify negotiation strategies and tactics. We propose an algorithm to map Statechart models of negotiation protocols into web service orchestrations and we report on the current implementation of our framework.     

A Relationship Governance Perspective of Organizational Buyers' Supplier Choice Decisions

Although the transaction cost analysis (TCA) has long been used by marketing and management scholars to study organizational buyers' make-or-buy decisions, it sheds limited light on their choice behavior beyond the make-or-buy trade-off. In the meantime, many organizational purchase decisions are structured around which independent supplier to buy from, rather than a typical make-or-buy decision. This study extends existing research on TCA by applying this theoretical framework to explore why organizational buyers make purchases from among independent suppliers. The article posits that (1) two forms of relationship governance—buyer trust and market (i.e., the relative dependence between the buyer and supplier)—help explain the differences in buyer decision-making uncertainty involving independent suppliers, which further influences the buyers' propensity to purchase; and that (2) trust further influences the buyers' propensity to purchase due to its effect on customer perceived value. The empirical study based on organizational purchasing decisions lends support to the predictions of the relationship governance theory.     

The Impact of Electronic Commerce on Procurement

Internet technology has been increasingly used to enhance the global competitiveness of various business applications through the widespread electronic commerce (EC) functions. Many Internet-based systems have been designed and developed for supply chain management (SCM) in various areas such as computer, garment, and publishing industries, which mainly center on communication infrastructure, coordination between production and distribution, and procurement functions with security mechanisms. However, EC is not a panacea. On many occasions, participants (including buyers, sellers, and enablers) face various risks and overhead during the deployment of a new technology. In this article, we present the impact of EC on procurement processes in supply chains, highlighting the issues of buyers, sellers, and the transaction processes involved. The procurement processes are classified into preprocurement (sourcing), procurement (quotation, negotiation, order placement, and transaction), and postprocurement (delivery). Moreover, a four-phase migration model of procurement onto the Internet is introduced to illustrate the technical, security, and financial requirements in the deployment process of EC. The migration model not only gives a development guideline of procurement functions, but also provides an evaluation framework of e-procurement. An industrial example is used to illustrate the corresponding evolution as a result of EC deployment. The paper concludes with a summary of EC impact and future research directions.     

B2B Negotiation Support: The Need for a Communication Perspective

Negotiation support is an important challenge for business-to-business e-commerce that is still poorly supported in current information systems. One reason is that negotiation processes are much harder to formalize than the business processes in the fulfilment phase. The goal of this paper is to provide the basis for a formal analysis of different types of electronic negotiations which can help developers of future negotiation support systems. The analysis is performed from a communication perspective, in particular, Habermas' theory of communicative action. Using this perspective, a distinction can be made between norm-oriented, goal-oriented and document-based negotiation. Whereas traditional modeling methods take a data-oriented view, the theory of communicative action supports a communication-oriented view that provides more insight in the logic of negotiation processes. The analysis forms the basis for the negotiation support prototype implemented within the ESPRIT project MeMo (Mediating and Monitoring Electronic Commerce) which was aimed at B2B e-commerce for SMEs in Europe.     

Exploring the impact of product service quality on buyer commitment and loyalty in B TO B relationships

Purpose: The purpose of this study is to understand and empirically test causal relationships among components of product service quality and commitment and buyer loyalty in business-to-business (B to B) relationships.

Methodology/approach: Data were collected through a web-based survey from 314 buyers of B to B manufacturers in Korea.

Findings: Product quality enhances all three types of commitment in B to B relationships, service quality is positively associated with affective commitment, and support quality has a significantly positive effect on affective and normative commitment. Also, the moderating effects of competitive intensity are significant. If competitive intensity is low in the buyer’s market, product quality and service quality play important roles in deriving buyer commitment; however, if competitive intensity is high, support quality is effective in maintaining long-term committed relationships with buyers.

Research implications: To fully consider product service quality in this study, we established support quality, product quality, and service quality as discrete components of product service quality.

Practical implications: Previous quality-related works have focused on products and services with little research about support activities, and the literature is lacking empirical analyses of support activities. However, this study elucidates the importance of operational and technical support activities in B to B relationships. Specifically, in a fiercely competitive market, a high-quality consumer support strategy is shown to be highly effective in maintaining long-term committed relationships with buyers.

Originality/value/contribution: We analyzed the relationships among components of product service quality and commitment and buyer loyalty in B to B transactions. Our detailed results will help firms develop context-specific quality management strategies at the product service level in order to strengthen customer loyalty.

An Examination of Trust Dimensions across High and Low Dependence Situations

Purpose: Relationship marketing literature has provided support of a multidimensional trust construct; however, there is little consensus on its structure. This article builds on existing theory to propose and empirically test a three-dimensional trust construct including ability, integrity, and benevolence dimensions. Furthermore, the article examines this conceptualization of the construct across different relationship types as established by dependence form.

Methodology: We choose to use a scenario/survey data collection method to replicate specific relationship types for a national purchasing agent sample. This method allows us to obtain adequate sample sizes to compare the relative importance of trust dimensions using structural equation modeling.

Findings: We found empirical evidence to support a three-dimensional trust construct for use in further examination of buyer–seller relationships. In addition, we found differential importance of those dimensions across different relationship forms.

Research Implications: By providing empirical support for a multidimensional trust construct and further specifying the importance of each dimension in various relationship forms, we hope to provide a strong foundation on which to build further trust research.

Practical Implications: In examining trust among purchasing agents, we hope to provide a strong foundation for salespeople to understand how their actions impact their long-term relationships. Understanding that trust in a relationship involves more than simple integrity or completing promises should help boundary spanners develop stronger ties.

Contribution: The main contribution of the article is the concept that trust needs to be researched in ways other than simply asking “Do you trust your supplier?”     

On the Effects of Dispositional and Situational Variables on the Motivation of Industrial Buyers

Using survey data from a sample of fleet purchasing managers, we explore the motivational process of industrial buyers. The results reveal direct and indirect links between self-esteem and both extrinsic and intrinsic motivation. The indirect effects of self-esteem on motivation come through industrial buyer responsiveness to leader behavior and formal authority. We explore the implications of integrating dispositional and situational factors in a single model of industrial buyer motivation, both for marketers who seek to better understand their customers and for purchasing managers.

The impact of buyer dependence on buyer opportunism in buyer–supplier relationships: The moderating role of relational norms

The impact of buyer dependence on opportunism against the supplier is examined in this research. Extant literature provides support for both a positive and an inverse relationship between these constructs. In this research, these competing predictions are subsumed under a more general model where the effect of dependence on opportunism is moderated by the level of relational norms present in the buyer–supplier relationship. Results of an experiment with purchasing managers and one replication provide support for the hypotheses that (a) dependence and opportunism will be positively related under low relational norms, and (b) dependence and opportunism will be inversely related under high relational norms. © 1997 John Wiley & Sons, Inc.     

Business-to-Business Electronic Commerce Success: A Supply Network Perspective

DeLone and McLean (2004) have advanced an electronic commerce (EC) success model and suggest that it can be extended to investigating EC success in different contexts. However, the EC success model has not been empirically validated in the context of business-to-business (B2B) EC. The purpose of this study is to gain a better understanding of EC value and success within the B2B environment. Accordingly, we introduce an extended version of DeLone and McLean’s (2004) EC success model, and test hypotheses regarding the associations between various success dimensions using the data collected from 122 supply chain units. In addition to providing support for most of the hypotheses suggested by DeLone and McLean’s (2004) EC success model, our results indicate that other success dimensions, such as EC readiness, must be considered for successful EC in B2B environments. The research findings provide practitioners with clarity on the levers of B2B e-commerce success within the supply chain unit level of analysis. Overall, the study’s results contribute to theoretical development in the area of business value creation and EC success, and present a basis for further research in these fields.
