Knowledge management has garnered attention due to its role of maintaining competitive advantage. Creating and sharing knowledge is an essential part of managing knowledge. However, the best knowledge is underutilized because employees tend to seek knowledge through their informal networks, not reach out to other sources for obtaining the best knowledge. Prior studies on informal networks pointed out a negative influence of heavy reliance on learning through informal networks but they paid little attention to a structure of informal networks and its impacts on diffusion of knowledge. The aim of our study is to show impacts of informal network on knowledge management by employing a network structure and investigating diffusion of knowledge within it. Our study found out that performance of learning becomes lower in a highly clustered network. Creating random links such as serendipitous learning can improve performance of knowledge management. When employees rely on a knowledge management system, creating random links is not necessary. Costs of adopting knowledge affect performance of knowledge management.

Agent technology has been widely applied in today's electronic business, such as mobile agents, multi-agent information systems, etc. In particular, multi-agent systems have been applied as powerful simulation tools to study complex business networks composed of various self-interested trading firms and/or human beings. In this paper, we build an integrated model that consists of a multi-agent B2C market model and a B2B trade network model, and incorporate more reality than much of prior work. Then with this model, we carry out experimental studies on two different strategies that are common in electronic business - 'loyal' strategy (retailers try to build stable cooperation with suppiers to ensure material supply) and 'cost-saving' strategy (retailers try to reduce cost by choosing suppliers with lower wholesale price).

Cross-border e-commerce has emerged as a crucial force in stabilizing China's foreign trade, driving the transformation and upgrade of China's foreign trade, and contributing to global economic development and stability. As a result, promoting the high-quality development of cross-border e-commerce has become a common challenge within the Chinese industry. However, with the rapid growth of cross-border e-commerce, it faces new phenomena and challenges, such as a mix of quality, fierce competition, and price competition. Brands serve as distinguishing markers for identifying entities, and brand building is a prudent choice for achieving high-quality development in cross-border e-commerce. This article utilizes brand theory, employing a combined qualitative and quantitative approach, with a specific focus on key elements within the operations of cross-border e-commerce enterprises. Through an analysis of the key elements influencing the formation and development of brands within the internal operations of Chinese cross-border e-commerce enterprises, it investigates their internal formation mechanisms and assesses the significance of these critical factors in influencing brand formation. The research process is based on data from overseas consumers, conducting empirical analysis, ultimately providing certain guidance for brand development in cross-border e-commerce enterprises.

This study aims to investigate the overall relationship between the deterring and facilitating factors in export activities of the small and medium export companies. Nine export deterring factors are analyzed by multinational dimensional scaling(MDS) method to identify key dimensions underlying those factors. Perceptual mapping shows that some factors such as brand image, operating capital and e-trade infra are found similar in its degree of difficulties in export activities. Regression analysis shows that government export promotion measures might play an effective export facilitating factors to ease the export deterring factors like market information and manufacturing skill. Whereas difficulties arising from e-trade infra, operating capital, and brand image might be eliminated by internal competency of company, difficulties from distribution channel might be lessened by overseas orientation of chief executive of company.

The purpose of this paper is to study the send and receive of the message in the TEDI System. The TEDI System replaces a series of trade documents with electronic date, and it realizes secure and reliable transactions of data among parties by means of open networks, such as the Internet. The TEDI system is composed of Web browsers, TC Serves, a RSP Server, and Certification Servers. TEDI has development the system and legal frame work. Exporters, importers, carriers, banks insurance and companies those who engage in the trade releated business have tested TEDI system and evaluated the legal frame work from the practical point of view. TEDI is now refining the system and preparing for the service. A fundamental feature of the TEDI System is the attribution to participants of data messages through public key certificates issued by certification authorities that allow for verification of digital signatures. Access to servers maintained by such certification authorities also takes place through the internet. In principle, certificates used by any reputable certification authority may be employed as long as they are compatible with X.509 V3.

In 2003, the Uniform Commercial Code(UCC) which is a kind of model law to unify commercial law between several states in US was amended to use electronic document of title including bill of lading. It is the second following the Australia legislation in 1996. Also, the Korean government amended Commercial Act and made the Presidential Decree for using electronic bill of lading in 2008. In this paper the authors reveal the characteristics of the clause of UCC for electronic bill of lading. The characteristics of the clause are on the technical neutrality of the signature, the possibility of reissuance in alternative medium, and adoption of the concept of "control." It helps to suggest some implications for Korean government authority. The authors suggest the amendment of the Presidential Decree to the Korean government authority to use additionally digital signature authorized by non Korean government such as VeriSign. It will activate the use of electronic bill of lading issued by Korea repositary out of Korea.
