摘要：In recent years, several organizations have implemented nonmandatory information and communication systems that escape the conventional behavioral logic of understanding acceptance and usage from a normative perspective of compliance with the beliefs of others. Because voluntary systems require users' volitional behavior, researchers have traced recent implementation failures to a lack of user commitment. However, gaps in our understanding of volitional usage behavior and user commitment have ...

摘要：Managing electronic trading partner relationships is a key to successful development of an interorganizational systems (IOS) network. Firms often exercise their power and offer reciprocal investments to their trading partners in developing an IOS network. However, limited effort has been made to empirically validate their effects on increasing IOS usage between trading partners. This paper gauges the effects of these two relational factors-power and reciprocal investments-within the context of...

摘要：Data mining techniques provide a popular and powerful tool set to generate various data-driven classification systems. In this paper, we investigate the combined use of self-organizing maps (SOM) and nonsmooth nonconvex optimization techniques in order to produce a working case of a data-driven risk classification system. The optimization approach strengthens the validity of SOM results, and the improved classification system increases both the quality of prediction and the homogeneity within ...

摘要：Knowledge represents a critical resource in the modern enterprise. But it is dynamic and distributed unevenly. Capitalizing on this dynamic resource for enterprise performance depends upon its rapid and reliable flows across people, organizations, locations, and times of application. From a technological perspective, this points immediately to the design of information systems to enhance knowledge flows. The problem is, the design of information systems to enhance knowledge flows requires new ...

摘要：Strategic sourcing, defined as a firm's key business process to identify, evaluate, configure, and negotiate purchases in important spend categories while managing long-term supplier relationships, is playing a significant role in sourcing strategies. The adoption of e-sourcing, defined as the use of business software (for example, using application service providers to conduct online procurement auctions) to automate or augment the aforementioned key business process, has been growing rapidly...

摘要：This research provides empirical evidence of the role of information technology (IT) as an enabler of growth in firms. We postulate that as a firm grows larger, a superior IT infrastructure increases the productivity of other inputs by controlling the complexity-related costs that the firm incurs as it increases in size. In the empirical analysis to support this view, we find that firms with high-growth expectations increase their IT spending as their free cash flow increases, whereas low-grow...

摘要：Despite their potential to significantly reduce transaction costs for both buyers and sellers, e-marketplaces have struggled. Recent literature has examined the value propositions of e-marketplaces and proposed conceptual frameworks for their analysis. In this research, we move beyond conceptual analysis by developing a game theoretic model of return-on-investment (ROI)-driven e-marketplace participation growth. This model provides insights into expected e-marketplace growth and participation,...

摘要：As business-to-consumer online shopping grows, e-commerce channel providers will need to explore ways to anticipate consumers' needs to deliver an efficient shopping experience. Yet the consumers' decision-making process and its relationship to the selection of the online channel are not well understood. Utilizing Simon's decision-making model, we examined support for decision-making phases using 134 online consumers. We also extended the model to include consumers' cost savings and time savin...
