Contagion effects of electronic commerce diffusion: Perspective from network analysis of industrial structure

This study presents a quantitative method for investigating the diffusion of e-commerce adoption using social network analysis methodologies. The contagion effects on innovation diffusion are examined by two different social network models: the cohesion model, which is based on diffusion by direct communication, and the structural equivalence model, which is based on diffusion by similarity of network position. This study then empirically examines a sample of e-commerce diffusion taken from the Taiwan's industrial structure in 2001. The analytical results show that e-commerce diffusion among firms in Taiwan exhibits both contagion effects, but that the mimetic behavior is predicted better by network position than by interactions with others.

The impact of market freedom on the adoption of third-party electronic marketplaces: A fuzzy AHP analysis

Electronic-marketplace (EM) is an innovative model for interfirm transactions that are undertaken via the Internet. However, in view of higher investment costs and other associated risks, many small and medium-sized enterprises (SMEs), instead of establishing their own EMs, turn to adopt third-party-hosted EMs. In literature, most relevant studies to the adoption of the third-party-hosted EM were conducted on the research contexts of free market. Industries under the protection of government policies may have limited degree of market freedom, different from industries without these protection policies. Thus, this study intends to compare the decision choice of EM adoption between industries with various degree of market freedom. The decision choice of EM adoption consisted of many strategic factors that were constructed in terms of a three-layer hierarchical structure proposed in this paper. A fuzzy analytic hierarchical process (Fuzzy AHP) was utilized to estimate the relative importance of these individual strategic factors involved in the decision-making process of adopting third-party EMs. The research findings indicated there were some similarities and differences in the decision choice between the two industries of interest. The variety of market freedom can account for the differences in the decision choice of EM adoption. In addition to enhancing our understanding of the EM adoption decision of participative companies, the research findings also provide insightful information to third-party EM providers so that they may improve the effectiveness and efficiency of resource allocation.

A change in market microstructure: the switch to electronic screen trading on the New Zealand stock exchange

The New Zealand Stock Exchange (NZSE) switched from open outcry trading to an electronic screen trading system on June 24, 1991. The change was made by the members of the exchange to improve the trading system and to reduce costs. This paper investigates empirically whether improvement was achieved through a reduction in transaction costs. The tests and results focus on order-flow migration to the exchange from alternative execution locations and changes in bid-ask spreads. On balance, we conclude that transaction costs have declined.     

电子商务路在何方

目前电子商务专业虽然是一个热门专业,但对于其专业的毕业生却热不起来。电子商务的学生到底能学到什么,高校电子商务专业课程设置是一个重要的课题。就其专业课程设置可以说有两个方向.即一是面向技术(Technology oriented)的电子商务教育,英文可以称为:Technol-ogy-oriented E-Business(缩写为TOEB);一种是面向管理(Managementoriented)的电子商务教育,英文可以称为:Management-oriented E-Business(缩写为 MOEB)。所以对于电子商务专业教育不能大而全,应该选其一而精。
