By analyzing some receivers' behaviors of internet advertising, the paper constructs a behavioral structure model based on the flow structure. Receivers' online flow experience is a function determined by receivers' skill, attentiveness and cyber environmental challenge, restricted to interactive speed and perception of media environment. It studies the relationship among motivation of using internet, online durational time, interactivity, attitudes and purchase intentions. The paper also examines the actual effects of internet advertising.
