B2B transaction was expected to dominate in the global market and thus many e-marketplaces have been built since 1999 in Korea. However, only a few e-marketplaces are thriving and the future of B2B e-marketplaces except MRO area seem to be uncertain. This paper explores why B2B transactions only in MRO area are rapidly increasing and examines the competing structure and business models of MRO e-marketplace. Business models of MRO e-marketplaces are various among different countries. However, they can be classified as three business models:information portal model, purchasing agent model, open market model. It is not easy to answer which business model is most competitive because each models have their own advantages and functions. Information portal model can be easily applied for the e-marketplace which operates off-line enterprises. Purchasing agent model is favorable to the e-marketplaces which has already obtained buyers and sellers. Open market model is desirable to the e-marketplace which has excess to global market.

본 논문에서는 저속 네트워크 사용자를 지원하기 위해 기존의 웹 기반 B2B 시스템을 확장하였다. 클라이언트와 서버 사이에 공유된 데이터의 일관성을 보장하기 위해 타임스탬프 트리를 이용한 데이터 변화 탐지 방법을 제안하고, 시뮬레이션을 통해 제안된 방법의 성능을 분석하였다. 타인스탬프 트리의 단말 노드들이 일양 분포로 변경되는 최악의 조건에서, 시뮬레이션 결과는 데이터 갱신율이 $15\%$ 이하일 때 제안된 방법이 순차 탐지보다 효율적임을 보였다. A사의 웹 기반 건설 MRO B2B 시스템을 2004년 4월부터 2004년 8월까지 관찰한 결과에 따르면, 월 평균 데이터 갱신율은 $7\%$ 이하였다. 따라서 제안된 방법은 실질적으로 데이터 변화 탐지 성능을 향상시켰다. 또한 제안된 방법은 서버가 클라이언트들이 복제한 데이터를 저장할 필요가 없기 때문에 서버의 저장 공간 사용이 줄었다.

The purpose of this research is to investigate economic factors that determine characteristics of B2B e-Marketplaces. From a previous research work, we classify B2B e-Marketplaces into four forms: MRO Hubs, Catalogue Hubs, Yield Managers, and Exchanges. This classification is based upon "What businesses buy" and "How businesses buy." In an attempt to identify economic factors that determine e-Marketplace forms, we employ three economic factors: buyer/seller relationships, features of products traded, and characteristics of industries or markets. Through extensive literature reviews, we have selected six variables which can be used to explain reasons for different e-Marketplace forms: asset specificity and information asymmetry for the buyer/seller relationship, standardization and price variability for the product features, entry barrier and market volatility for the market characteristics. This research conducts six in-depth case studies to explain that "Why different forms of e-Marketplace emerge?" The research framework intends to provide link between e-Marketplace forms and six economic variables. Six case studies are based on interviews with CEO or team managers of e-Marketplace firms. This study has found six economic variables, explaining well reasons for different e-Marketplace forms. Research findings are summarized as propositions so that survey-type research can be conducted with a large number of samples in the future.
