A research model was developed to examine the relationship between the anticipated benefits of electronic commerce and competitive strategies. A survey questionnaire was sent to 2000 electronic shopping malls in Korea, and 102 usable responses were obtained. The survey asked about the anticipated benefits from using electronic commerce. The survey also asked about three strategies that they have been following to achieve business competitiveness. The results provide useful guideline to develop appropriate strategies and plans for effectively deploying and managing the use of the electronic commerce. Customer responsiveness was the most important factors among six benefit factors, namely customer responsiveness, market responsiveness, economies of production, internal organizational efficiency, overall performance, and flexibility. Overall performance also predicted a focus strategy whereas flexibility predicted a cost leadership strategy.
