With the open system environment of the Internet and the intensive communication requirement of being a remote shopping channel, consumer-based electronic commerce becomes more complex and dependent on trust development in a business relationship. This paper examines the concept of trust and proposes a trust development life-cycle for EC adoption. Besides, it suggests and analyses a number of antecedent factors toward initial trust formation. These factors include information quality, web interface design and company reputation. This paper contributes to a better understanding of the EC trust concept, which is important for the successful implementation of consumer-based electronic commerce.
