This study examined which factors were related to the amount of consumer information and the level of consumer satisfaction in electronic commerce. The sample (n＝ 426) was composed of those who had already engaged in e-commerce. T-test and ANOVA were completed to investigate how the amount of information and the level of satisfaction differ by socioeconomic, internet-related, and purchase-related characteristics of the consumers. The results of this study were as follows: First, consumers who were female and college graduates were more likely to search lots of information in e-commerce. The amount of consumer information was positively related to both the years of internet experiences and the time used on internet per day. Second, consumers who were male, aged on 30s, and who were college graduates with higher incomes were more likely to gather information about product functions, while consumers who were female with less experiences of internet shopping were more likely to consider the brand name. Third, income and education level were positively associated with the level of consumer satisfaction in e-commerce. Those who have experienced lots of purchase in e-commerce were generally satisfied with the shopping in e-commerce. Fourth, the amount of consumer information was positively related to the level of consumer satisfaction, especially satisfaction regarding product qualify and the convenience of shopping in e-commerce.
