The new paradigm, which is called Electronic Commerce (EC), has greatly influenced not only enterprises but also other part of our society. Many goods have been actively transacted through EC all over the world. But there is a great difference between agricultural products and industrial products in terms of selling and buying behavior. Industrial products are well standardized and time-invariant in quality but agricultural products are not. Even the domestic distribution channels of agricultural products are much complex and are not modernized with internet technology. In this study, we first identify the behaviors of electronically transacting agricultural products and then develop and EC architecture far agricultural products in Korea. We suggest that EC for agricultural products focuses on B2B (Business to Business) model and various agricultural information should be distributed from B2B market over all supply chain and demand chain channels.
