Accompanied with the development of the Internet, people access information through the Internet more frequently. Comparison sites use different kinds of search engines, offer a convenient way for retailers and consumers to interact. We examine the interaction between comparison sites, retailers and consumer behavioral patterns. The retailers advertise and sell homogeneous products and the consumers choose to shop. This is done either through web based stores or physical stores. In this analysis, we find that the level of competition between retailers in a platform play a critical role in the behaviors of all three agents; the consumer, the retailer itself,and the comparison sites. Also our analysis will further explain the role of the social welfare effect. We also find that the competition between platforms may worsen the efficiency of the allocation of markets. However, the collusion between platforms has its positive effects to the whole market because platforms have a stronger incentive to raise level of competitiveness between retailers. Such incentive increases the efficiency of the allocation of markets.
