我们首先看看为消费者提供服务平台的站点,这类站点中最显眼的是雅宝、网猎这样的竞价网站。他们主要是采用 P to P 方式,有时也包括了 B to C,为用户提供场地进行商品的买卖、竞价和信息交流。P to P 的方式好在网站无须负太多责任,仅仅是为用户提供竞价场地和信息,但是赢利较少。B to C 虽然有更多的赢利,网站却要在和商家的合作中担些风险。这两种方式,可以为网站扩大用户群,而用 We first look at the sites that provide service platforms for consumers. The most prominent sites of this type are auction sites such as Albemarle and Webhunting. They mainly use P to P, sometimes including B to C, to provide users with venues for merchandise purchase, bidding, and information exchange. The P to P method is good because the website does not have to bear too much responsibility. It only provides users with bidding venues and information, but it has less profit. Although B to C has more profit, the website has to take some risks in cooperation with the merchants. These two methods can be used to expand the user base for the website.
